First Affiliated Hospital, Zhejiang University School of Medicine, China
The First Affiliated Hospital has treated 104 patients who tested positive for CoVID-19 in 50 days. It has achieved zero deaths in patients diagnosed, zero patients misdiagnosed, and zero infections in medical staff. Its experts documented real treatment experience when combating the virus, 24 hours a day, and quickly published this Handbook.
Public Health Emergencies often lead to Stigma, Discrimination and Abuse towards certain communities and social groups, or affected people. Within the context of CoVID-19, this has already happened … with the disease being recklessly and maliciously associated with a specific population or nationality.
Independent Oversight & Advisory Committee for the WHO Health Emergencies Programme
Established to facilitate on-line communication and collaboration internationally, as well as to provide Frontline Medical Teams around the world with the necessary communication channels to share practical experience about fighting, controlling and overcoming the pandemic.
An Agency of the European Union (EU) … ECDC is closely monitoring the CoVID-19 Outbreak, providing Public Health Guidance and advice on Response Activities to EU Member States and the EU Commission.
The European Commission, together with several Partners, launched this Platform on 20 April 2020 … to enable the rapid collection and sharing of available Research Data. The Platform, part of the ERAvsCorona Action Plan (download PDF File, 153 Kb), is a significant effort to support Researchers in Europe and around the World in the fight against the CoronaVirus pandemic.
Vulnerable People, such as Those with Activity Limitations (#PwAL) or Disabilities (#PwD), are more impacted by #CoronaVirus/#CoVID19. These impacts can be mitigated if simple Self-Protection Measures are taken.
As Fire Departments and local Authorities Having Jurisdiction (AHJ’s) continue planning to respond to CoronaVirus/CoVID-19 occurrences in their communities, the IAFC Coronavirus Task Force has developed a guide to identify best practices … and key recommendations which are based largely on guidance from the U.S. Centers for Disease Control and Prevention (CDC – https://www.cdc.gov/) and the World Health Organization (WHO – https://www.who.int/emergencies/diseases/novel-coronavirus-2019). When planning for CoVID-19, Fire Chiefs must also be sure to collaborate with local Stakeholders, both individuals and organizations !
2020-03-23: The Grenfell Fire Inquiry’s Phase 1 Recommendations (Part V in Volume 4 of the Phase 1 Report), were published on 30 October 2019. The initial issues covered in those Recommendations are fragmentary, lack depth and coherence … and in the case of Fire Alarms, with just one indirect reference to them in Paragraph #33.22 … they are in serious error …
.
Colour image showing the Volume 4 Cover Page of the Grenfell Tower Inquiry Phase 1 Report. The Phase 1 Recommendations are contained in Chapter #33, on Pages 771-780. Click to enlarge.
[ Paragraph #33.22 ] There were no plans in place for evacuating Grenfell Tower should the need arise. I therefore recommend:
d. that all high-rise residential buildings (both those already in existence and those built in the future) be equipped with facilities for use by the fire and rescue services enabling them to send an evacuation signal to the whole or a selected part of the building by means of sounders or similar devices ;
.
FUNDAMENTALS OF A SOLUTION
1. A Fire Alarm (more precisely from here on, a Fire Detection & Warning System) is a critical safety feature in all buildings … ALL BUILDINGS … from the smallest and most simple, to the biggest and most complex … no exceptions !!
In order to survive in a fire emergency, Vulnerable Building Users need more time to react, and evacuate, than other occupants/users. The valuable time provided by early, accurate and precise detection is the only way to effectively facilitate this. The ‘Required Time’ to prepare for evacuation depends on many factors, e.g. building complexity, familiarity of users with evacuation routes, range and severity of user activity limitations, etc.
It follows, therefore, that if building occupants/users have to wait 15, or 20, or 30 minutes before firefighters arrive at the fire scene (Full Response Time*) and ‘an evacuation signal to the whole or a selected part of the building’ is only then sent by those firefighters … all of that valuable evacuation time for vulnerable building users has been lost. This is ridiculous, and makes no sense whatsoever. This Recommendation must be rejected out of hand, and ignored !
[ *Full Response Time: The time interval from the receipt of an emergency communication at the primary public safety answering point (#PSAP) to when emergency response units are initiating action or intervening to control a fire incident. ]
.
Colour photograph showing the Single, Narrow Staircase (1.040 metres in width between a handrail on one side of the staircase and a bare wall on the other side) in London’s Grenfell Residential Tower. This staircase, which was inadequately protected from fire, heat and smoke, was not wide enough to facilitate the ‘contraflow’ circulation of firefighters entering, while occupants evacuated at the same time. Without a Fire Alarm in the building, occupants could not have known that a serious Fire Emergency was in progress … especially Vulnerable Building Users accommodated high up in the Tower … and they remained in place (‘stayed put’). Once firefighters arrived at the scene, occupant evacuation using this staircase became impossible or extremely difficult. Click photograph to enlarge.
Important Note: In Chapter #34: ‘Looking Ahead to Phase 2’ of Moore-Bick’s Phase 1 Report, Volume 4 … Paragraph #34.14 states …
A question was raised about the width of the stairs, given that they provided the sole means of access to the upper floors of the tower for firefighters as well as the sole means of escape for the occupants. However, the stairs appear to have complied with requirements of the legislation in force at the time of their construction and the expert evidence supports the conclusion that they had sufficient capacity to enable all the occupants of the building to escape within a reasonable time. This aspect of the building will not, therefore, be the subject of further investigation in Phase 2.’
Astounding ! Absurd !! FUBAR !!!
.
All Fire Emergency Warning Systems must be designed to accommodate People with Hearing Impairments. Audible and visual warning devices must be provided together, as a single combined unit. This is particularly important in noisy and isolated building spaces, e.g. bathrooms, small meeting rooms. Vibrating devices, such as pagers or mobile phones, can be integrated into a building’s fire emergency warning system in order to provide any individual with a tactile emergency alert.

Important Note: Audible sounders, on their own, are never a sufficient Fire Emergency Warning !
.
2. The Purpose of a Fire Emergency Warning System is to provoke calm, efficient and adaptable evacuation movement by ALL building users/occupants at the earliest possible stage in a fire incident, without causing user confusion, disorientation or panic. In all building types, therefore, a reliable, informative and accessible fire emergency warning system must be installed, and such a system must always have a fire protected electrical supply.

The purpose of a Fire Emergency Warning System is to provoke calm, efficient and adaptable evacuation movement by ALL building occupants at the earliest possible stage in a fire incident, without causing user confusion, disorientation or panic. During a Fire Emergency, STANDARD MOVEMENT TIMES DO NOT EXIST. Click image to enlarge.
.
3. To provoke a Calm Response from Building Users … the output from Fire Emergency Warning Devices, e.g. light, sound and messages, must be adapted to the local context of people and building surroundings.
Fire Emergency Audible Warnings … A sufficient number of low-output audible sounders, i.e. between 60-80 dB, must be specified for effectiveness. Small numbers of sounders with high output (in order to reduce costs) should never be specified, as this can lead to confusion, disorientation and panic attacks among some building users/occupants. The output of sounders must be adapted to suit interior surroundings, e.g. in small spaces with hard surfaces a lower sound output will be adequate.
Colour image. The output from Fire Emergency Audible Sounders must be between 60-80 dB. Click image to enlarge.
Important Note: When they are asleep, hearing-able children (around ten years of age and under) … and hearing-able older people (around 65 years of age and over) are more difficult to wake and rouse sufficiently for evacuation when alerted by an audible signal alone.
Fire Emergency Visual Warnings … Light strobes/beacons must be clearly visible. To reinforce #1 above … light strobes/beacons must be placed in wash rooms and in other locations within buildings where people may be alone ; they must also be placed in noisy environments.
A sufficient number of low-output strobes/beacons must be specified for effectiveness. Small numbers of strobes/beacons with high output (in order to reduce costs) should never be specified, as these produce a glare which may cause confusion, disorientation and panic attacks among some building users/occupants. The light output of strobes/beacons must be adapted to suit interior surroundings, e.g. in dark rooms.
For light strobes/beacons, a slow rate of flash is important, i.e. no faster than once every two or three seconds, in order to encourage a calm response from building users/occupants and to avoid photosensitivity seizures. Most importantly, the flash of one strobe/beacon must be synchronized with the flashes of all other light strobes/beacons in view.
.
Colour video clip (.gif). The output from Fire Emergency Visual Strobes / Beacons must be no faster than one flash every two or three seconds. The flash rate shown above is too fast ! Click to run video clip.
Fire Emergency Voice Message Warnings … Are essential to improve Warning Credibility. In other words, building users are far less likely to sit around wondering, waiting to see whether this is a ‘real’ fire emergency, a false alarm, a practice evacuation, or an electrical error. Verbal or voice messages must be short and contain appropriate warning information which is easily assimilated. The speaker should be distinct and easy to understand. Live messaging during a fire emergency is preferred over pre-recorded, standard messages. In today’s multi-cultural social environment, messages must be transmitted in at least two to three different languages, as appropriate.
Fire Emergency Directional Warnings … Combination sounder, visible strobe/beacon, and voice messaging Fire Emergency Warning Devices are now a mainstream technology, are readily available, and are being specified in new and existing buildings.
.
Colour image showing a combination Fire Emergency Directional Audible Sounder, with Voice Messaging capability. Click image to enlarge.
Audible directional signalling must be installed when dealing with difficult building configurations, e.g. in large open office layouts/spaces with minimal signage … where building users/occupants are unfamiliar with their surroundings in modern shopping centres/malls and other complex building types … or visibility of high-level signage may be reduced because of smoke logging.
Directional sounders, which guide building users during a Fire Evacuation towards Exits, Areas of Rescue Assistance and Lift/Elevator Lobbies, must be positioned at carefully chosen, suitable locations. Once reached, a directional sounder must also have a voice messaging capability in order to inform people about the next phase of evacuation.
4. Fire Emergency Warning Systems must be Accessible (for People with Activity Limitations), i.e. capable of transmitting a warning in many formats in order to ensure that all users/occupants perceive and act upon the warning in a calm manner and, thereafter, that effective evacuation movement commences without delay. Warning Credibility improves in direct relation to the type and number of different warning formats.
.
As well as indirectly referring to Fire Detection and Warning Systems, Paragraph #33.22 in Moore-Bick’s Phase 1 Recommendations has some other things to say about Evacuation. So this is an opportune moment to discuss some practical and human issues concerning Fire Emergency Evacuation … and, straight away, to deal with an unexpected consequence arising from the current CoronaVirus/CoVID-19 Emergency …
CoronaVIRUS / CoVID-19 PANDEMIC
There have been widely reported instances, in many countries, of panic buying in shops because of the 2020 CoronaVirus/CoVID-19 Emergency … but the photograph below illustrates an example of a panic reaction by building management. This appears to be a crime scene … the yellow and black tape is so dramatic. In a real Fire Emergency, many building users/occupants will be reluctant to use this final fire exit ; they will not have the time to read the small print on a notice ; they will attempt to re-trace their path of evacuation and find another exit.
Colour photographs showing how, as a panic reaction to the 2020 CoronaVirus/CoVID-19 Emergency, a Final Fire Exit has been blocked off from normal, everyday use. Click to enlarge.
This panic reaction by building management IS a serious impediment to Fire Evacuation !
Whatever the Motives of Building Management …
in countries which have Fire Codes / Regulations, this action is illegal ; and
in these days, when a wide range of ‘smart’ technologies is readily available … this action is inexcusable.
.
SOME PRACTICAL FIRE EVACUATION ISSUES
A Skill is the ability of a person, resulting from competent training and regular practice, to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal. All building occupants/users must be skilled for evacuation to an external ‘place of safety’, which is at a safe and remote distance from the fire building. Practice fire evacuations must be carried out sufficiently often to equip building users, particularly vulnerable users, with this skill, i.e. at least once every six months ; in complex building types, practices should be carried out more often. Prior notification to occupants/users, and regular scheduling of practice evacuations should be avoided.
Familiarity with Fire Evacuation Routes will be fostered and greatly improved by means of normal, everyday use by occupants/users. This is an important task for pro-active Building Management in existing buildings … and an important aspect of new building design for Architects and Fire Engineers.
While the transmission of fire emergency warnings in many formats will increase Warning Credibility, close observation of past tragic ‘real’ fire events, e.g. the WTC 9-11 Attacks in New York City, shows that initiation of evacuation and the actual process of evacuation itself can be problematic. An interesting, easily assimilated and user-targeted skills programme of training should incorporate practical solutions to deal with the following typical problems:
Fire Emergency Preparedness: Irregular attendance of building occupants/users at fire prevention and safety training sessions, and participation in practice fire evacuations. Users not being familiar with a building’s fire emergency management plan and not knowing who is in charge … not using a building’s fire evacuation route(s), particularly staircases, during practices … or having no information about where to assemble after evacuating … or, once at a place of safety, not having any head count or identification process ;
Delaying Activities Inside The Fire Building: Once building occupants/users decide to evacuate, but before moving to evacuate, they gather personal effects … seek out friends/co-workers … search for others … make phone calls/send tweets … finish tasks/turn off computers … wait around for instructions … change shoes … and try to obtain permission to leave ;
Delaying Activities Outside The Fire Building: Once outside the building’s final fire exit, but before moving directly to a place of safety, building occupants/users stop to see what is happening … look for friends/co-workers … look for a phone … do not know where to go … or, within the ‘danger zone’ of the fire building, stop to receive medical attention.
It may seem obvious that Fire Evacuation Routes must also be Accessible (for People with Activity Limitations), which also makes routes much safer for every other building user … and sufficiently wide to accommodate Contraflow (emergency access by firefighters or rescue teams into a building and towards a real fire, while building users are still moving away from the fire and evacuating the building) … a harsh lesson learned from the 2001 WTC 9-11 Attacks and the 2017 Grenfell Tower Fire. Since they are new, strange and unusual for many building designers, and most fire engineers … these aspects of building performance are overlooked in nearly every building.
Practice Evacuations should include exercise of the buddy system ; fire safety fittings, e.g. portable fire extinguishers ; and fire evacuation devices intended for use by people with activity limitations which will require more intensive training.
.

Important Note: During fire emergencies, People with Activity Limitations must be permitted to keep possession of their own personal Facilitation / Mobility Aids.
.
SOME HUMAN FIRE EVACUATION ISSUES
The actual people who use and occupy buildings are individuals. They are different from each other, and they each have a different range of abilities (in relation to self-protection, independent evacuation to an external place of safety remote from a fire building, and active participation in a building’s fire emergency management plan), behaviour and manner of perceiving their surroundings. Two apparently similar people will also show variations in how they react to and behave in any specific situation, particularly a fire emergency.
Ability / Disability is a Continuum – a gentle gradient on which every person functions and acts at different levels due to personal and environmental, i.e. external, factors.
In situations of severe stress, e.g. during a fire emergency in a building, where there is a lack of preparedness for such an event, a lack of familiarity with evacuation routes, lack of reliable evacuation information, lack of competent leadership and clear direction, and the presence of smoke, user/occupant confusion, disorientation and panic will occur. Standard evacuation movement times will also be non-existent. In addition, people with activity limitations must then deal with many physical barriers which routinely impede their evacuation from buildings, e.g. fire resisting doorsets which are difficult to open, steps along evacuation routes and at final fire exits.
In the case of people with a mental or cognitive impairment, there is a particular need to encourage, foster and regularly practice the adaptive thinking which will be necessary during evacuation a real fire incident.
People with respiratory health conditions will not be able to enter or pass through smoke. People with visual impairments will require continuous, linked tactile and/or voice information during the whole process of fire evacuation. People with psychological impairments, i.e. vertigo and agoraphobia, will be unable to use fire evacuation staircases with glass walls in high-rise buildings. Because of the stigma still associated with disability in many countries, some users/occupants who will need assistance during a fire emergency will be reluctant to self-identify beforehand. Other people may not even be able to recognize that they have an activity limitation or a health condition.
Meaningful Consultation with a person known to occupy or use a building, for the purposes of receiving his/her active co-operation and informed consent (involving a personal representative, if necessary), is an essential component of adequate pre-planning and preparation for a fire emergency.
Building Designers, Fire Engineers and Firefighters should be aware of the following human conditions:
Agoraphobia: A fear of open spaces.
Commentary: Agoraphobia is one of the most commonly cited phobic disorders of people seeking psychiatric or psychological treatment. It has a variety of manifestations, e.g. a deep fear of leaving a building, or of being caught alone in some public place. When placed in threatening situations, agoraphobics may experience a panic attack.
Anosognosia: A neurological disorder marked by the inability of a person to recognize that he/she has an activity limitation or a health condition.
Dementia: Any degenerative loss of intellectual capacity, to the extent that normal and occupational activities can no longer be carried out.
Panic: A sudden overwhelming feeling of anxiety, which may be of momentary or prolonged duration.
Panic Attack: A momentary period of intense fear or discomfort, accompanied by various symptoms which may include shortness of breath, dizziness, palpitations, trembling, sweating, nausea, and often a fear by a person that he/she is going mad.

I was very pleased to make a Presentation at both events, adapted to suit an Irish context, on … ‘Sustainable Fire Engineering – Necessary Professional Transformation For The 21st Century’ … which continues to evolve.
Sustainable Fire Engineering: The creative, person-centred and ethical Fire Engineering response, in resilient built form and smart systems, to the concept of Sustainable Human and Social Development … the many aspects of which must receive synchronous and balanced consideration !
Sustainable Fire Engineering Internet: www.sfe-fire.eu Twitter: @sfe2016dublin
Presentation Abstract
Annual Fire Losses, both direct and indirect, amount to a very significant percentage of Gross Domestic Product (#GDP) in all economies, whether they are rich or poor … and result in enormous environmental devastation and social disruption. Some losses have not yet been fully identified, e.g. environmental impact … while others are not yet capable of being fully quantified, e.g. business interruption, brand and reputation damage. Globally, fire statistics still remain unreliable. In all cases, however, the waste of valuable human and natural resources caused by preventable fires is unsustainable and no longer acceptable.
From an entirely different perspective … Sustainable Buildings are presenting every society with an innovative and exciting re-interpretation of how a building functions in response to critical energy, environmental, climate change and planetary capacity pressures … an approach which has left the International Fire Engineering and Firefighting Communities far behind in its wake, struggling to develop the necessary ‘creative’ and ‘sustainable’ fire safety strategies.
The Aim of Sustainable Fire Engineering (#SFE) is to dramatically reduce direct and indirect fire losses in the Human Environment (including the social, built, economic, virtual, and institutional environments) … to protect the Natural Environment … and, within buildings, to ensure that there is an effective level of Fire Safety for All Occupants, not just for Some, over the full building life cycle.
The following Priority Themes for SFE lie outside, or beyond, the constrained and limited fire safety objectives of current fire regulations, codes and standards – objectives which do not properly protect society, a fire engineer’s clients, or the facility manager’s organization:
Fire Safety for ALL, not just for Some. Nobody left behind !
Firefighter Safety. Everyone goes home ! It is easy to dramatically improve firefighter safety with building design. So, why haven’t NIST’s 2005 and 2008 WTC 9-11 Critical Recommendations been properly implemented anywhere ?
Property Protection. Fire damage and post-fire reconstruction/refurbishment are a huge waste of resources. On the other hand, protection of an organization’s image/brand/reputation is important … and business continuity is essential. Heritage fire losses can never be replaced.
Environmental Impact. Prevention of a fire is far better than any cure ! But prevention must also begin by specifying ‘clean’ technologies and products. Low Pressure Water Mist Systems are not only person/environment-friendly and resource efficient … they are absolutely essential in airtight and hyper energy-efficient building types (e.g. LEED, PassivHaus, BREEAM) in order to achieve an effective level of fire safety for all occupants, and firefighters. [ Note: Environmental Impact Assessment (#EIA) has been superseded by Sustainability Impact Assessment (#SIA).]
Building Innovation, People and Their Interaction. Fire engineers and firefighters must begin to understand today’s new design strategies.
Sustainable Design and Engineering. Wake up and smell the coffee ! Legislation can only achieve so much. Spatial planners, building designers and fire engineers must subscribe to a robust Code of Ethics * which is fit for purpose in the Human Environment of the 21st Century.
Sustainable Fire Engineering Solutions are …
Adapted to a local context, i.e. climate change/variability/extremes, social need, geography, economy, and culture, etc ;
Reliability-based – lessons from real extreme and hybrid events, e.g. 2001 WTC 9-11 Attack, 2008 Mumbai/2015 Paris/2016 Brussels Hive Attacks and the 2011 Fukushima Nuclear Incident, are applied to frontline practice ;
Person-centred – real people are placed at the centre of creative endeavours and due consideration is given to their responsible needs, and their health, safety, welfare and security in the Human Environment ;
Resilient – functioning must be reliable during normal conditions, and include the ability to withstand, adapt to and absorb unusual disturbance, disruption or damage, and thereafter to quickly return to an enhanced state of function.
As we approach the First Anniversary of the Grenfell Tower Fire Tragedy, in England, on 14 June … a few days ago, on 4 June 2018, the first batch of Grenfell Expert Witness Reports were uploaded (https://www.bbc.com/news/uk-44356660) to the Grenfell Tower Inquiry Website (https://www.grenfelltowerinquiry.org.uk/) for public view.
At this time, in London … multiple, fragmented investigations are taking place into the actual fire incident … the role of the Local Authority, and building management … those involved in the refurbishment (‘tarting up’) design and construction … the fire services, particularly their ‘Stay Put’ Policy and how it adversely impacted on vulnerable Tower occupants during the emergency … and the highly flawed regulatory model of Building and Fire Codes with light-touch Control, which is still operating in England. One of Murphy’s Laws immediately springs to mind with regard to the intended ineffectiveness of this overly-complex process !
Colour photograph showing Grenfell Tower in the background … undergoing an almost complete ‘cover-up’ … with, in the foreground, mementos of the Fire Tragedy fixed to railings by local residents. Click to enlarge. Photograph taken by CJ Walsh. 2018-04-29.
Many other countries have adopted some or all of this modern English regulatory model which, after the repeal of an older Bye-Law format, has been shaped by political expediency, cost-effectiveness and general ineptitude … with little or no adaptation to local conditions in the adopting jurisdictions. Ireland adopted this model with some, but not a lot, of adaptation.
Fire Safety In Ireland ?
On 6 June 2018 … while that investigative activity was hitting the headlines in England … Minister Eoghan Murphy, T.D., Ireland’s Minister for Housing, Planning and Local Government, quietly published the Report: ‘Fire Safety in Ireland’ … http://www.housing.gov.ie/local-government/fire-and-emergency-management/fire-safety/eoghan-murphy-publishes-report-fire … by a High-Level Task Force within his Department’s National Directorate for Fire and Emergency Management, after serious concerns and fears had been expressed in the public media that a similar fire tragedy might also occur in this jurisdiction.
To be crystal clear … this Report is a Bureaucratic Whitewash … an insult to the Public ! Nice sounding technical ‘blarney’ camouflages a failure to deal directly with critical issues, and answer concerns … while other important issues are avoided altogether.
May 2018 – Ireland’s Department of Housing, Planning & Local Government Report
Expanding on my comments in the Interview with Barry Lenihan, on RTE Radio 1’s Drive Time early evening news programme on Friday (2018-06-08) …
A. Initially, Irish Local Authorities were requested to carry out a preliminary survey to identify all buildings of more than six storeys, or 18m in height. Specifically, they were asked to identify those buildings which had an external cladding system which might be a cause for concern.
This height threshold of six storeys/18m is arbitrary … an external cladding system can be just as much a cause for concern in a building which is lower. Imagine discarded cigarette butts or a rubbish fire at the base of such a system … and the resulting speed of fire spread and development across a building façade !
B. The highly flawed regulatory model of Building and Fire Codes, with light-touch Control, which resulted in the Grenfell Tower Fire Tragedy … we also have. Wake up and smell the coffee Ireland !
At the beginning of the 1990’s, when Ireland had been persuaded by the European Commission to finally introduce legal, national building regulations having a functional format … our National Authority Having Jurisdiction, in desperation, grabbed the then Approved Documents for England & Wales … brought them back to Ireland, put Irish covers on them, and originally called them ‘Technical Documents’ … but, after seeing a tiny ray of inspiring light, later changed their title to the more accurate ‘Technical Guidance Documents’ ! This hunger for adopting all things English which are fire safety related continues to this day … with a similar, ongoing division of Technical Guidance Document B: ‘Fire Safety’ into 2 Separate Volumes.
This may have been a convenient response under pressure … but it has been very short-sighted. It has impeded the growth of a comprehensive and coherent philosophy on Safe, Inclusive, Age-Friendly, Resilient, Sustainable Planning, Design and Construction Codes/Controls which is suited to an Irish context and responsible local needs (not desires!).
C. Everywhere … this Report has a lot – too much – to say about Fire Risk Assessment ! After the Grenfell Tower Fire, however, Fire Risk Assessments must only be carried out by competent persons … and the process of Fire Risk Assessment, itself, must be radically improved ! And of course, prior to any Risk Assessment … a proper Fire Hazard Appraisal must be carried out.
D. To accurately present Fire Safety Trends in Ireland … it is not enough to furnish reliable fire fatality statistics. It is also necessary to produce reliable fire injury statistics … and reliable information on direct/indirect socio-economic losses.
E. The quality of fire safety related construction on Irish Building Sites continues to be very poor and problematic. Fire Compartmentation is nowhere near being adequately – never mind acceptably – reliable ! And during the last few years we have had quite a number of close-calls concerning fire incidents in medium-rise residential buildings.
F.Fire Evacuation for people with activity limitations is still handled atrociously in our current building regulations. This is ironic because, on 20 March 2018 last, Ireland had to be dragged screaming to ratify the U.N. 2006 Convention on the Rights of Persons with Disabilities (CRPD) !
.
Positive Progress By Another Path !
1. Abandon the outdated English functional requirements in THEIR building regulations … and adopt a far better, more up-to-date body of functional requirements which is already on the Irish Statute Books … Annex I of the European Union’s Construction Products Regulation 305/2011. And because there are important horizontal linkages between requirements … immediately finish the ridiculous current separation between Fire Safety requirements and all of the other requirements. And yes … new Technical Guidance Documents will have to be drafted.
.Regulation (EU) No 305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down harmonized conditions for the marketing of construction products and repealing Council Directive 89/106/EEC
2. Yes … ‘Persons Having Control’ of buildings have responsibilities with regard to fire safety. But that is only one side of the coin ! National and Local Authorities Having Jurisdiction have greater responsibilities.
If we are at all serious about Consumer Protection … bad, inadequate, faulty construction must be prevented beforehand … it is too late, too costly and, in many cases, too impractical to correct afterwards. Self Regulation by building design professions and construction organizations is NO Regulation ! Stringent, independent technical control inspections must be carried out on all projects by Building Control personnel … which used to happen in Dublin City/County and Cork City/County prior to the introduction of legal building regulations in the early 1990’s … and, depending on complexity, must also be carried out at critical stages during the construction process.
Building Control Sections in all Local Authorities must be properly resourced with competent personnel, equipment, training and support infrastructure.
Inspections concerning compliance with all functional requirements in the building regulations, including fire safety, must be carried out only by Building Control Personnel. Chief Fire Officers must not be allowed to manage or be involved in any aspect of Building Control. On the same project … a Disability Access Certificate Application and a Fire Safety Certificate Application must be inter-linked and overlap sufficiently, showing no gaps in compliance. Inspections must be carried out in connection with all Certificate Applications. Building Control personnel must satisfy themselves that actual construction at least matches, if not improves upon, what is shown in design documentation.
Building Control Inspection Reports must be made available for public view.
3.Firefighters are NOT a disposable Social Asset ! National and Local Authorities Having Jurisdiction … and some Chief Fire Officers … must begin to understand this fundamental truth !
Fire Services in all Local Authorities must each be properly resourced according to local needs … with competent personnel, equipment, training and support infrastructure. Shared provision of resources looks very neat on paper but, in practice, works very badly. Refer to the Grenfell Tower Fire and London Fire Brigade having to borrow firefighting equipment from other Fire Services.
After the 2015 Tianjin Regional Fire Devastation, in China, and the 2001 WTC Attacks on 9-11, in New York City … front line firefighters must be supported by Specialist Hazard Appraisal and Structural Engineering Units.
For Firefighter Safety in buildings and to quickly find people with activity limitations waiting in Areas of Rescue Assistance and/or other survivors in different locations … a portable and reliable Thermal Imaging Camera is an essential piece of every firefighter’s equipment.
And Firefighter Safety begins with good building design. In all but the most simple building types, Circulation Routes must be designed for Contraflow … people moving away from a fire in a building and towards safety while, at the same time, heavily equipped firefighters are entering the building and moving towards the fire.

There is no place for ‘Stay Put’ Policies in Irish Residential Buildings of any height.

After The Grenfell Tower Fire !
Further to my last Blog, dated 2017-10-10 …
The 2017 Fire in England was not an extraordinary fire. Since the beginning of this decade, we continue to see a series of such fires: South Korea (2010) – UAE & France (2012) – Chechnya (2013) -Australia (2014) – UAE, Azerbaijan & UAE again (2015) – UAE (2016) – UAE & Russia (2017) – Turkey (2018).
With regard to Command & Control of Large Scale Emergencies … English AHJ’s should have paid attention to the 2005 & 2008 U.S. National Institute of Science & Technology (NIST) Recommendations following the 9-11 WTC Buildings 1, 2 & 7 Collapses.
The Fire Safety Objectives in current Building & Fire Codes/Regulations are very limited. In Ireland, this is clearly stated in Technical Guidance Document B …
‘ Building Regulations are made for specific purposes. Part B of the Second Schedule to the Building Regulations is therefore primarily concerned with the health, safety and welfare of persons. The fire safety measures outlined in this guidance document are intended for the protection of life from fire.’
Only insofar as it is necessary to protect the lives of able-bodied building users/occupants … is there a concern for property protection.
There is only inadequate, token concern for the protection of people with disabilities.
Client organizations, facility managers, building designers, construction organizations … and journalists … must fully comprehend these limits.
In the photograph below … look closely at the External Firefighting Operations at the bottom of the Tower. There are limits to what can be achieved from outside a building !

.
A Fire Suppression System (Water Sprinklers/Mist/Hybrid) is an essential Fire Protection Measure in ALL Medium and High-Rise Residential Buildings … which include Apartment Blocks, Hotels, Hostels, Student Accommodation & Social Housing, i.e. ANYWHERE there is a Sleeping Hazard.
A Reliable and Credible Fire Detection & Warning System is an essential Fire Protection Measure in ALL Buildings … and must be capable, under the control of Building Management, of transmitting warnings in many formats, i.e. Audible + Visual + Multi-Lingual Voice + Tactile.
Fire Evacuation Routes in Buildings must be designed for CONTRAFLOW … people moving away from a fire and towards safety while, at the same time, heavily equipped firefighters are entering the building and moving towards the fire.
Good Fire Evacuation Route Design is INTUITIVE and OBVIOUS. In many buildings, however, this is not always the reality. Effective Fire Evacuation Signage … comprising high-level signage, low-level signage, with both supplemented by photoluminescence … must be installed in ALL Buildings.
For the purpose of protecting Vulnerable Building Users in Fire Emergencies, ALL Lifts/Elevators in Buildings must be capable of being used for Evacuation.
Fire Risk Assessments must NO LONGER be carried out by people WITHOUT COMPETENCE in Fire Engineering AND Building Design & Construction … and the Fire Risk Assessment Process itself must be thoroughly re-examined and upgraded.
The creative, person-centred and ethical fire engineering response – in resilient built or wrought form, and using smart systems – to the intricate, open, dynamic and continually evolving concept of Sustainable Human & Social Development … the many aspects of which must receive balanced and synchronous consideration.
SFE PRIORITY THEMES
1. Fire Safety for ALL – Not Just for SOME People. Nobody Left Behind !
Do Building Designers and Fire Engineers have any understanding of what it feels like to be left behind in a fire emergency … perhaps to die ?
Do Building Designers and Fire Engineers have any understanding of the ‘real’ people who use their buildings … or their ‘real’ needs ?
2. Firefighter Safety – It’s So Easy to Dramatically Improve Their Safety At A Fire Scene ! A Firefighter’s Protective Clothing and Equipment are not enough !
Conscious awareness of this issue by Building Designers and Fire Engineers is required … and appropriate education/training.
3. Property Protection – A Minor Code Fire Safety Objective, Insofar As It Is Necessary to Protect the Safety of Building Users … Only !
Fire damage and post-fire reconstruction/refurbishment are a huge waste of resources. On the other hand, protection of an organization’s image/brand is important … and business continuity is essential.
Heritage Fire Losses cannot be replaced !
To properly protect Society and the interests of a Client/Client Organization … Building Designers and Fire Engineers are ethically bound to clearly explain the limitations of Code and Standard Fire Safety Objectives to their Client/Client Organization.
4. Environmental Impact – Prevention Is Far, Far Better Than Cure. Instead of resisting, and erecting ‘professional’ barriers … Spatial Planners, Building Designers and Fire Engineers must begin to properly understand this concept … and act ethically to defend and protect the environment !
Environmental Impact: Any effect caused by a given activity on the environment, including human health, safety and welfare, flora, fauna, soil, air, water, and especially representative samples of natural ecosystems, climate, landscape and historical monuments or other physical structures, or the interactions among these factors ; it also includes effects on accessibility, cultural heritage or socio-economic conditions resulting from alterations to those factors.
This Planet – Our Common Home – can no longer suffer the scale and extent of total devastation seen after the 2015 Tianjin (China) Regional Fire Disaster !
5. Building Innovation, People and Their Interaction – Fire Engineers and Firefighters must understand current approaches to more sustainable building design, the ‘real’ people who use the built environment, and the complex interactions between both.
People with Activity Limitations (E) / Personnes à Performances Réduites (F): Those people, of all ages, who are unable to perform, independently and without aid, basic human activities or tasks – because of a health condition or physical/mental/cognitive/psychological impairment of a permanent or temporary nature.
The above Term, in English and French, includes …
people who experience difficulty in walking, with or without a facilitation aid, e.g. stick, crutch, calliper or walking frame ;
wheelchair users ;
the very young (people under 5 years of age), frail older people, and women in the later stages of pregnancy ;
people who are visually and/or hearing impaired ;
people who suffer from arthritis, asthma, or a heart condition … or any partial or complete loss of language related abilities, i.e. aphasia … or who have a cognitive impairment disorder, including dementia, amnesia, brain injury, or delirium ;
people impaired after the use of alcohol, other ‘social’ drugs e.g. cocaine and heroin, and some medicines … or following exposure to environmental pollution and/or other irresponsible human activity, e.g. war or terrorism ;
people who experience a panic attack in a real fire situation or other emergency ;
people, including firefighters, who suffer incapacitation as a result of exposure, during a real fire, to smoke and poisonous/toxic substances and/or elevated temperatures.
6. Sustainable Design & Engineering – Get With The Programme ! The extensive United Nations 2030 Sustainable Development Framework Agenda was overwhelmingly agreed and adopted in 2015.
Sustainability Impact Assessment (SIA): A continual evaluation and optimization process – informing initial decision-making, design, shaping activity/product/service realization, useful life, and termination or final disposal – of the interrelated positive and negative social, environmental, economic, institutional, political and legal impacts on balanced and equitable implementation of Sustainable Human & Social Development.
‘Carrots and Sticks’ can only achieve so much. Spatial Planners, Building Designers and Fire Engineers must – individually and as a group – subscribe to a robust Code of Ethics which is fit for purpose in today’s Human Environment.
New CIB W14: ‘Fire Safety’ Research Working Group VI Reflection Document: ‘Sustainable Fire Engineering Design, Construction & Operation’, which will establish a framework for the future development of Sustainable Fire Engineering.
Preparation of this Document will soon begin, and the following issues will be explored:
Conceptual Framework for Sustainable Fire Engineering (SFE), with a necessary accompanying Generic SFE Terminology ;
Strategy for Future SFE Development ;
Implementation of 2005 & 2008 NIST WTC 9-11 Recommendations ;
Fresh, New SFE Research Agenda ;
Resilient Implementation of SFE Research Agenda.

PRIORITY THEME 1 – FIRE SAFETY FOR ALL (2017)
The Fire Safety Task Group, chaired by CJ Walsh, of ISO Technical Committee 59, Sub-Committee 16, Working Group 1, has already commenced the revision and further development of the fire safety texts in International Standard ISO 21542 (2011): ‘Building Construction – Accessibility & Usability of the Built Environment’.
The main effort, initially, has been focused on developing a coherent Fire Safety for All approach … token consideration, or a post-design graft-on, of the fire safety needs of people with activity limitations do not work, and are unacceptable.
‘ The creative, person-centred and ethical Fire Engineering response, in resilient built form and smart systems, to the concept of Sustainable Human and Social Development – the many aspects of which must receive balanced and synchronous consideration.’
.
Organized by FireOx International (Ireland, Italy & Turkey), in joint collaboration with Glasgow Caledonian University’s School of Engineering & Built Environment (Scotland) … and having a widely multi-disciplinary attendance from the U.S.A., Hong Kong SAR (China), Spain, Finland, Scotland, Norway, Germany, England, The Netherlands and Ireland … SFE 2016 DUBLIN was a unique, and very successful, two-day gathering within the International Fire Engineering and Fire Service Communities.
SUSTAINABLE FIRE ENGINEERING fulfils a Critical Role in the realization of a Safe, Resilient and Sustainable Built Environment 4 ALL !
SUSTAINABLE FIRE ENGINEERING facilitates Positive Progress in implementing the United Nation’s 2030 Sustainable Development Agenda, which incorporates 17 Sustainable Development Goals and 169 Performance Targets !
SUSTAINABLE FIRE ENGINEERING fast-tracks Proper Compliance with the 7 Basic Performance Requirements – functional, fully integrated and indivisible – in Annex I of European Union Construction Products Regulation 305/2011 !
.
A NECESSARY & LONG OVERDUE TRANSFORMATION !
A Building is a permanent construction, complying with basic performance requirements and capable of being easily adapted … comprising structure, essential electronic, information and communication technologies (EICT’s), and fabric (non-structure) … having a minimum life cycle of 100 years … and providing habitable, functional and flexible interior spaces for people to use.
Building Users have a wide and varied range of abilities and behaviours … some having discernible health conditions and/or physical, mental, cognitive, psychological impairments … while others, e.g. young children, women in the later stages of pregnancy and frail older people, are also particularly vulnerable in user-hostile, inaccessible environments. Not everyone will self-identify as having an activity limitation because of the high level of social stigma associated with ‘disability’. Building designers and fire engineers must accept that building users have rights and responsible needs ; the real individual and group fire safety requirements of vulnerable building users must be given proper consideration by both design disciplines, working collaboratively together.
Real Building Users have a wide and varied range of abilities … and during a Fire Evacuation, they will NOT behave like ‘marbles or liquid in a computer model’ ! People with Disabilities, on their own, account for approximately 20% of populations in developed countries … more in developing and the least developed countries.
Following the savage 2008 Mumbai Hive Attack in India, and the more recent 2015 and 2016 Attacks in Europe, i.e. Paris, Brussels, Istanbul and Berlin … it is entirely wrong to assume that the main and/or only targets will be specific high-risk buildings types, i.e. Tall/High-Rise, Iconic, Innovative and Critical Function Buildings (refer to 2005 & 2008 NIST WTC 9-11 Recommendations). All buildings and adjoining/adjacent public spaces must be carefully assessed for the risk of direct or collateral involvement in an Extreme Man-Made Event.
It is a fundamental principle of reliable and resilient structural engineering that horizontal and vertical structural members/elements of construction are robustly connected together. All buildings must, therefore, be capable of resisting Disproportionate Damage. The restriction of this requirement, within some jurisdictions, to buildings of more than five storeys in height is purely arbitrary, cannot be substantiated technically … and ethically, must be disregarded.
Fire-Induced Progressive Damage is distinguished from Disproportionate Damage – a related but different structural concept – by the mode of damage initiation, not the final condition of building failure. This phenomenon is poorly understood. But, unless it is impeded, or resisted, by building design … Fire-Induced Progressive Damage will result in Disproportionate Damage … and may lead to a Collapse Level Event (CLE), which is entirely unacceptable to the general population of any community or society. All buildings must, therefore, be capable of resisting Fire-Induced Progressive Damage.
All buildings must also be carefully assessed for the risk of involvement in a Severe Natural Event, e.g. earthquakes, floods, landslides, typhoons and tsunamis.
In all of the above Risk Assessments … the minimum Return Period (also known as Recurrence Interval or Repeat Interval) must never be less than 100 years.
Reacting to surging energy, environmental and planetary capacity pressures … with accelerating climate change … Sustainable Buildings are now presenting society with an innovative and exciting re-interpretation of how a building is designed, constructed and functions … an approach which is leaving the International Fire Engineering and Fire Service Communities far behind in its wake, struggling to keep up.
Colour ‘infographic’ showing the design features of 1 Bligh Street, Sydney CBD, Australia … ‘tall’/skyscraper commercial office building, completed in 2011 … designed by Ingenhoven Architects (Germany) and Architectus (Australia). Can Fire Engineers understand this new design approach … and then collaborate, actively and creatively, within the Project Design Team ?Black and white plan drawing of 1 Bligh Street (Level 26), Sydney CBD, Australia … a ‘sustainable’ office building … BUT … Effective ‘Fire Safety for All’ in this building ? Has Firefighter Safety been considered ?? Property Protection ??? Business Continuity ???? The very harmful Environmental Impacts of Fire ?????
Passive and Active Fire Protection Measures, together with Building Management Systems (whether human and/or intelligent), are never 100% reliable. Society must depend, therefore, on firefighters to fill this reliability ‘gap’ … and to enter buildings on fire in order to search for remaining or trapped building users. This is in addition to their regular firefighting function. Therefore, there is a strong ethical obligation on building designers, including fire engineers, to properly consider Firefighter Safety … should a fire incident occur at any time during the life cycle of a building.
Structural Serviceability, Fire Resistance Performance and ‘Fire Safety for All’ in a building must, therefore, be related directly to the local Fire Service Support Infrastructure … particularly in developing and the least developed countries. AND … Fire Codes and Standards must always be adapted to a local context !
Colour photograph showing knotted sheets hanging from high-level windows which were used for ‘escape’ by guests … clearly indicating a catastrophic failure of fire protection measures and management within the building. Fire and smoke spread quickly throughout the multi-storey hotel, resulting in 12 dead, and over 100 injured (approximately 1/3 critically).Colour photograph showing a guest rescue by ladder. Notice the condition of the ladder and firefighter protection. Fire safety in a building must be related directly to local Fire Service Support Infrastructure … particularly in developing and the least developed countries.
The fire safety objectives of current Fire Codes and Standards are limited, usually flawed … and will rarely satisfy the real needs of clients/client organizations, or properly protect society. Fire code compliance, in isolation from other aspects of building performance, will involve a consideration of only a fraction of the issues discussed above. There is once again, therefore, a strong ethical obligation on building designers, including fire engineers, to clearly differentiate between the limited fire safety objectives in Fire Codes and Standards … and Project-Specific Fire Engineering Design Objectives … and to explain these differences to a Client/Client Organization. Facility Managers must also explain these differences directly to an Organization’s Senior Management … and directly inform the Organization’s Board of Directors … as appropriate.SFE Mission: To ensure that there is an effective level of Fire Safety for ALL – not just for SOME – in the Built Environment … to dramatically reduce all direct and indirect fire losses in the Human Environment … and to protect the Natural Environment.
To transform Conventional Fire Engineering, as practiced today, into an ethical and fully professional Sustainable Design Discipline which is fit for purpose in the 21st Century … meaning … that fire engineers can participate actively and collaboratively in the sustainable design process, and can respond creatively with sustainable fire engineering design solutions which result in Effective Fire Safety for All in a Safe, Resilient and Sustainable Built Environment.
To bring together today’s disparate sectors within the International Fire Engineering (and Science) Community … to encourage better communication between each, and trans-disciplinary collaboration between all.
To initiate discussion and foster mutual understanding between the International Sustainable Development, Climate Change and Urban Resilience Communities … and the International Fire Engineering and Fire Service Communities.
The realization of a Safe, Inclusive, Resilient & Sustainable Built Environment demands a concerted, collaborative, very creative and widely trans-disciplinary effort at national, local, regional and international levels across the whole planet – Our Common Home. The informed operation of appropriate legislation, administrative procedures, performance monitoring and targeting, and incentives/disincentives, at all of these levels, will facilitate initial progress towards this objective … but not the quantity, quality or speed of progress necessary. Our time is running out !
This Code of Ethics applies … for those who subscribe to its values … to policy and decision makers, and the many different individuals and organizations directly and indirectly involved in the design, engineering, construction, and operation (management and maintenance) of a Safe, Resilient & Sustainable Built Environment for All.
The Purpose of this Code of Ethics is to guide the work of competent individuals and organizations in a context where incomplete or inadequate legislation, administrative procedures and incentives/disincentives exist … but, more importantly, where they do not exist at all … and, amid much confusion and obfuscation of the terms, to ensure that implementation is authentically ‘sustainable’, and reliably ‘safe’ and ‘resilient’ for every person in the receiving community, society or culture … before it is too late !

Preparation of this Document will soon begin, and the following issues will be explored:
Conceptual Framework for Sustainable Fire Engineering (SFE), with a necessary accompanying Generic SFE Terminology ;
Strategy for Future SFE Development ;
Implementation of 2005 & 2008 NIST WTC 9-11 Recommendations ;
And Maybe … if it hadn’t been that particular night, during all the festivities of New Year’s Eve 2015, we would never have heard about the Address Supertall Hotel Fire, in Dubayy (UAE). A long search on the Internet afterwards led to the detailed, post fire analysis report on the 2014 Lacrosse Docklands Fire, in Melbourne (Australia) … followed by some more searching, and a very large can of worms opened up … similar nasty façade (external fabric) fires in many, many countries … involving large chunks of flaming debris falling from terrific heights, carried by the wind to a significant distance away from the building of fire origin.

Some people have tried to suggest that the only reason for these fires is inadequate building codes/regulations. No … the reason for these fires is much more than that … it’s the ‘SYSTEM’ ! In other words, how the International Construction Sector is organized and goes about its ordinary, everyday activities and tasks. We must also talk about poor quality design and construction … and a lack of stringent, independent enforcement of effective building codes/regulations and standards. I have written this down many times before … Self-Regulation is NO Regulation !!
It is very clear that Conventional Fire Engineering … as currently practiced, internationally … is no longer ‘fit for purpose’. For discussion at SFE 2016 DUBLIN. Check out the Fire Conference Website: www.sfe-fire.eu … and on Twitter: @sfe2016dublin

IN IRELAND … A 2015 TERRACED HOUSING FIRE …
The general public was shocked and stunned, to put it mildly, by a very rapid and extensive 2015 Terraced Housing Fire on the outskirts of Dublin …
Click to enlarge.
[ See my Blog, dated 2011-04-06 … about a different, but related, 2011 Terraced Housing Fire in Terenure, a suburb of Dublin City.]
Click to enlarge.
[ Fast forward from 2011 … overtaking Priory Hall (see my series of Blogs) … to Longboat Quay, a large residential development on the south bank of the River Liffey, which flows through the middle of Dublin. A recent visual/surface inspection of one of the units there revealed not just a poor quality of construction … but a lack of care and attention, with a mixture of incompetence and ignorance thrown in for good measure.]
Click to enlarge.
The 2015 Terraced Housing Fire, shown above, should not have been a surprise to the ‘System’ in Ireland. Research carried out in the U.S.A., Belgium and The Netherlands since 2012, and a serious PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013 … have all shown that the modern home (highly insulated, airtight, packed with electronic equipment and wiring, and fast-burning synthetic furnishings, etc.) is the ‘perfect storm’ of fire conditions and outcomes. More open residential design + increased fuel loads + new construction systems and materials = faster development of fires, much reduced times to flashover, far less time for occupant evacuation, particularly people with activity limitations … and shorter building collapse times.
The time to flashover in modern high-performance housing, i.e. Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART … can be 7 times faster than in conventional/legacy housing … or less than 5 minutes, compared with just over 29 minutes !
All of this research can be found on the Links & Docs Page of the SFE 2016 DUBLIN Website.
Let us be crystal clear … there is nothing Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART about the post-fire scenes of destruction shown above. And only for the physical separation between terraces, which can be clearly seen in the last photograph … the fire would have kept spreading.
.
URGENT FIRE SAFETY RECOMMENDATIONS …
Without a balanced, proper approach to the issue of Fire Safety in this type of modern, high-performance housing … occupant safety is seriously threatened. And if, in the event of a fire incident, the occupants are asleep … or people with activity limitations are living in the house … that threat will be extremely grave indeed.
Reality – Reliability – Redundancy – Resilience !
So … what needs to change ? In Ireland, our immediate problem is Timber-Framed Housing (as shown above) … and the following is an outline of what must change … NOW !
Party Walls, i.e. the walls separating one house from another, must be constructed of solid masonry, with a uniform and uncompromised thickness of at least 200mm … plastered on both sides, not dry-lined, for adequate smoke resistance … and be continued above the roof covering for at least 300mm.
An effective Fire Detection System must be installed. The conventional ‘package’ of one smoke detector per floor in the hallway and staircase of a standard 2 storey semi-detached house is nowhere near being adequate.
An effective Residential / Domestic Fire Suppression System must be installed, e.g. low pressure water mist. See later post, dated 2016-06-13, for a costed notional installation.
If there is a Controlled Ventilation System, either mechanical or natural, in the house (for the purposes of air quality, heat exchange and energy conservation), it must be linked to the fire detection system. In the event of a fire incident, the Ventilation System must immediately cease operation, and remain ‘fully open’. This is in order to mitigate the build-up of high positive pressure, within a confined airtight space, caused by a developing fire … and to provide an exhaust route for smoke and toxic gases … during the short period of time prior to activation of the fire suppression system.
Intermediate Timber Floors and Evacuation Routes, including fire resisting doorsets, must be reliably protected from fire and smoke. The minimum period of fire and smoke resistance must be linked to local fire service support infrastructure. In other words, the local fire services must be allowed sufficient time to arrive at the scene of a fire in strength … to search for any occupants still remaining in the fire building … and to bring the fire under control.
Uppermost Ceilings under a trussed timber roof structure, including any trap doorsets into the roof space, must be similarly and reliably protected from fire and smoke. Once fire enters a roof space, the light trussed timber structure will collapse within a few minutes.
Front and Back Entrance/Egress Doors must be outward opening. In the 2013 German PassivHaus Apartment Fire, the occupant found it extremely difficult to open inward opening doors and windows because of the high positive pressure caused by the developing fire. This unusual phenomenon was confirmed in the 2015 Finnish Apartment Fire Tests, when much higher positive pressures were observed.
Internal Linings of External Walls must comprise 2 layers of plasterboard, with all joints staggered … steel fixed, at not more than 150mm centres. Once fire breaches the internal lining of an external wall, the whole building will become involved in the fire. Horizontal and vertical fire sealing behind these linings, even if properly installed (!), are too little and too late.
Frontline Firefighters must be supported by specialist structural engineering and hazard appraisal units … and light/portable/reliable Thermal Imaging Cameras must be recognized as a standard tool of firefighting.
.
SUSTAINABLE HOUSING & RESIDENTIAL BUILDINGS …
These building types are more popularly known as Green, PassivHaus / Passive House, LEED, Eco, Bio, BREEAM, +Energy, Zero / Low / Nearly Zero Carbon, or SMART, etc., etc, etc. In ALL of these cases, however, an Effective Residential Fire Suppression System MUST BE INSTALLED, e.g. low pressure water mist !
In everyday practice … Authorities Having Jurisdiction (AHJ’s), and the Organizations and Individuals responsible for the far-too-rapid construction of these innovative building types are either completely and blissfully ignorant, or callously and negligently in denial, about the seriously negative impacts on Occupant & Firefighter Fire Safety and Building Fire Protection.
BUT … slowly … more and more reliable evidence is being gathered ! Please visit the Links & Docs Page on: www.sfe-fire.eu … and also view this Presentation on some very interesting 2015 Apartment Fire Tests in Finland: www.youtube.com/watch?v=0Ss_ONolzLY
.
ENERGY CONSERVATION & EFFICIENCY UPGRADING OF EXISTING BUILDINGS …
In refurbishment projects where insulation is fixed to the internal surfaces of external walls … similar fire safety problems exist, and they must be solved by reviewing the full checklist above. Refer again to the PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013 … and to the 2015 Apartment Fire Tests in Finland
2012-03-02: Please bear with me while I update you at the start of this post … rather than at the end, which would be more usual here … and logical.
[ In Ireland … a related problem, which continues to fester and cause a great nuisance in an everyday work environment … concerns the lack of proper, i.e. formal, recognition of electronic communications, and information in an electronic format, by public and private organizations … in spite of the following very clear legal text …
2000 Electronic Commerce Act (No. 27 of 2000)
Section 9 – Electronic Form not to Affect Legal Validity or Enforceability
Information (including information incorporated by reference) shall not be denied legal effect, validity or enforceability solely on the grounds that it is wholly or partly in electronic form, whether as an electronic communication or otherwise. ]

Yesterday afternoon (1 March 2012), we received the following e-mail communication from the Department of Environment, Community & Local Government (DECLG) …
Folks,
Could you please send me your submissions in either Microsoft Word or Excel as it it easier to copy and paste into the format that is required , it is proving rather difficult to copy from a PDF document.
Thank You
Claire Darragh, Architecture / Building Standards, DECLG.
.
I immediately replied …
Dear Claire,
Further to your informal e-mail message, which we received just a short while ago …
Please note that this is not an acknowledgement that the FireOx International Submission was received by the Department … and we certainly do not wish that you copy and paste anything relating to its contents anywhere else.
IF this is a Proper Public Consultation Process … you must adapt internal DECLG systems to suit the Submissions ! We will be communicating with the Minister’s Office concerning this issue.
Once again, I would ask you to properly acknowledge receipt of our Submission, dated 2012-02-14.
.
In connection with the original FireOx International Submission … I would also like to take this opportunity to advise you that:
Due to an error in ISO (International Standards Organization) … the publication of ISO 21542: ‘Building Construction – Accessibility and Usability of the Built Environment’, on 12 December 2011, was not notified to people directly involved in its development and drafting, or to the participating national standards organizations ;
and
In order to avoid the wide confusion which the term ‘Fire-Induced Progressive Collapse’ is continuing to cause at international level … the preferred term is now Fire-Induced Progressive Damage.
.
I have amended our Submission accordingly.
Kind regards.
C. J. Walsh, FireOx International – Ireland, Italy & Turkey.

2012-02-18: The following is the text of FireOx International’s Submission, dated 14 February 2012, to the Department of the Environment, Community & Local Government (DECLG) in Dublin … concerning the current review of the Irish Building Regulations Part B & TGD B … including, for good measure, some initial and very pertinent comments on the Irish Building Control Regulations.
None of these comments will come as any surprise to regular visitors here.
It should also be noted that the same comments are just as relevant in the case of the British (England & Wales) Building Regulations, Part B and Approved Document (AD) B !
.
Ms. Claire Darragh, Architecture & Building Standards Section, DECLG.
Dear Claire,
Thank you for this opportunity to advise the Department on some urgent and necessary improvements to Part B: ‘Fire Safety’ of the 2nd Schedule to the Building Regulations in Ireland … and its supporting Technical Guidance Document (TGD) B.
1. Some Initial Comments
The continuing debacle of the Priory Hall Apartment Complex, in Donaghmede Dublin 13, is just the tip of a very large iceberg in Ireland. Yet, when we now hear that there will be a ‘risk-based’ approach to Septic Tank Inspections, instead of an approach which involves inspecting all septic tanks … independently, competently and thoroughly … it is clear that the Minister, and senior officials in his Department, have failed to learn any lessons from ‘Priory Hall’.
What was happening on Irish construction sites during the Celtic Tiger boom years … has been happening for twenty years all over the country … more precisely, since the introduction of legal national building regulations in 1991, with NO effective building control … and, before that again, in those parts of the country outside of the major urban areas having legal building bye-laws AND effective building control, i.e. mandatory inspections by competent local authority personnel at the foundation level and drainage level of ALL projects … and, depending on the type of project, occasional or frequent inspections above ground level.
Over the years, local authority officials who carried out building bye-law inspections accumulated a considerable wealth of knowledge and understanding about local construction conditions and practices. This valuable resource, widely used by the construction industry at the time, has now been diluted and discarded.
PLEASE LEARN THE LESSONS FROM ‘PRIORY HALL’ !!
In connection with ALL Applications for Fire Safety Certificates (Part B) and Disability Access Certificates (Part M) … competent and thorough inspections must, from now on, be carried out by local authority personnel to confirm proper implementation of Part B & M, respectively, of the 2nd Schedule to the Building Regulations.
Furthermore … while on site, local authority personnel must not be discouraged, or restricted, from dealing with any other Parts of the 2nd Schedule to the Building Regulations. Under the present dysfunctional system, important horizontal linkages between different Parts of the 2nd Schedule are being widely disregarded and ignored, e.g. between Parts B & D, between Parts B & M, and between Parts B & A … or between Parts M & D, etc., etc !
European Union (EU) Council Directive 89/106/EEC has been repealed … and, instead, we now have EU Regulation No 305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down Harmonised Conditions for the Marketing of Construction Products.
Unlike the earlier EU Directive … this Regulation, applicable in all EU Member States, is binding in its entirety.
And although Annex I of EU Regulation 305/2011 will enter into force from 1 July 2013 … the Department should now prepare for, and slowly begin the process of, incorporating all of the Annex I Basic Requirements for Construction Works into the 2nd Schedule of the Irish Building Regulations.
SEE BELOW …
.
2. Firefighter Safety
Fully consistent with Basic Requirement for Construction Works 2(e), in Annex I of EU Regulation No. 305/2011 … Revise Part B Requirement 5 to read as follows …
B5 Firefighter Safety, and Access and Facilities for the Fire Service
A building shall be so designed and constructed that the safety of firefighters is adequately considered and, in the event of an outbreak of fire, that there is adequate provision for access for fire appliances and such other facilities as may be required to assist the fire service in the protection of life and property.
Two examples of issues which should be highlighted in a relevant revision/addition to TGD B’s Guidance Text:
The incorporation, in building designs, of alternative safe means of approach towards the scene of a fire by firefighters ;
The provision of wider staircases in buildings in order to facilitate the recovery of an injured/impaired firefighter during the course of firefighting operations.
.
3. Protection of Vulnerable Building Users from Fire
The European Union ratified the United Nations Convention on the Rights of Persons with Disabilities (CRPD) on 23 December 2010. Ireland has not yet ratified the Convention.
However … fully consistent with Ireland’s legal obligation, under Article 4.3 of the Treaty on European Union (TEU), to co-operate fully with EU Institutions in their implementation of this UN Convention … Revise Part B Requirement 1 to read as follows …
B1 Means of Evacuation in the Event of an Outbreak of Fire
A building shall be so designed and constructed that the protection of vulnerable building users is adequately considered and, in the event of an outbreak of fire, that there are adequate and accessible means of evacuation from the building to a place of safety remote from the building, capable of being safely and effectively used.
[ Use of the word ‘escape’, in the context of emergencies, should be strongly discouraged at all times. ]
Concerning TGD B’s Guidance Text … reference to ISO 21542: ‘Building Construction – Accessibility and Usability of the Built Environment’ will be more than sufficient.

4. TGD B’s Appendix A – Performance of Materials and Structures
2 Important Notes should be added to Paragraph A21 – Structural Fire Design …
In complying with Part B, reference should also be made to Part A of the 2nd Schedule of the Building Regulations, particularly Requirement A3 – Disproportionate Collapse ;
and
In order to show that a Fire Protection Material/Product/System for Structural Elements properly complies with Part D … it is also necessary, besides showing that it has been adequately fire tested, to show that the material/product/system is durable over a specified, reasonably long life cycle … and that it can adequately resist mechanical damage during construction of the building and, in the event of an outbreak of fire, during the course of that fire incident.
.
Specifically relating to Steel Structural Performance in Fire …
You should be aware that Table A1 and Table A2 are only appropriate for use by designers in the case of single, isolated steel structural elements.
In steel structural frame systems, no consideration is given in the Tables to adequate fire protection of connections … or limiting the thermal expansion (and other types of distortion) in fire of steel structural elements … in order to reduce the adverse effects of one steel element’s behaviour on the rest of the frame and/or adjoining non-loadbearing fire resisting elements of construction.
In the case of steel structural frame systems, therefore, the minimum fire protection to be afforded to ALL steel structural elements, including connections, should be 2 Hours. Connections should also be designed and constructed to be sufficiently robust during the course of a fire incident. This one small revision will contribute greatly towards preventing Fire-Induced Progressive Damage in buildings … a related, but different, structural concept to Disproportionate Damage …
Disproportionate Damage
The failure of a building’s structural system (i) remote from the scene of an isolated overloading action; and (ii) to an extent which is not in reasonable proportion to that action.
Fire-Induced Progressive Damage
The sequential growth and intensification of structural distortion and displacement, beyond fire engineering design parameters, and the eventual failure of elements of construction in a building – during a fire and the ‘cooling phase’ afterwards – which, if unchecked, will result in disproportionate damage, and may lead to total building collapse.

–rescuing people who are trapped in buildings, or for some reason, cannot independently evacuate a building which is on fire.
Compare for a moment, therefore, Part B5 in the Irish Building Regulations …
B5Access & Facilities for the Fire Service
A building shall be so designed and constructed that there is adequate provision for access for fire appliances and such other facilities as may be reasonably required to assist the fire service in the protection of life and property.
… with Essential Requirement 2 of the European Union (EU) Construction Products Directive 89/106/EEC …
2.Safety in Case of Fire
The construction works must be designed and built in such a way that in the event of an outbreak of fire:
– the load-bearing capacity of the construction can be assumed for a specific period of time ;
– the generation and spread of fire and smoke within the works are limited ;
– the spread of the fire to neighbouring construction works is limited ;
– occupants can leave the works or be rescued by other means ;
– the safety of rescue teams is taken into consideration.
Can you spot the difference ?Go to the last indent in Essential Requirement 2.
There is a complete and careless disregard for Firefighter Safety in the Irish Building Regulations … it isn’t even mentioned.And forget about any references to ‘firefighter safety’ in the guidance text of Technical Guidance Document B … there are none.
In July 2003 … the results of a U.S. Firefighter Disorientation Study, examining firefighter fatalities in the years 1979-2001, were released.This important Study was prepared by Captain William R. Mora of the San Antonio Fire Department in Texas.
Firefighter Disorientation – loss of direction due to the lack of vision in a building fire – is one of the oldest, least understood and deadliest hazards of firefighting inside a building.And according to the U.S. National Institute of Occupational Safety & Health (NIOSH) … disorientation usually precedes firefighter fatality.
Capt. Mora’s Study focused on 17 building fires in which disorientation played a major part in 23 firefighter fatalities.
In the cases studied, the typical Disorientation Sequence was as follows:
A fire in an enclosed building with smoke showing occurs. The arriving fire services immediately initiate an aggressive interior attack to search for the source of the fire. During the search, the source cannot be located and conditions deteriorate with the production of heat, smoke and prolonged zero visibility. As firefighters perform an emergency evacuation due to deteriorating conditions, hoseline separation occurs or tangled hoselines are encountered. Disorientation then occurs as firefighters exceed their air supply, are caught in flashovers or backdrafts, or are trapped by a collapsing floor or roof. When a firefighter is not located quickly enough, the outcome is a fatality or serious injury. The disorientation sequence usually unfolds in a building that does not have a sprinkler system or one that is inoperable.
The 17 Buildings displayed a wide range of architectural features … including differences in size, height and type of construction.In 100% of the fire incidents, however, the buildings had an ‘enclosed’ design with very few windows or doors (necessary for prompt ventilation and emergency evacuation by firefighters) in relation to the size of the building.They also included basements.
This ‘enclosed’ form was the result of Architectural Design or alteration after construction was completed.When owners altered a building, pre-existing windows or doors were closed up using materials such as plywood sheeting or brickwork.
Another Issue … a Fundamental Principle of Fire Engineering Design … after the WTC 9-11 Incident in New York … is to always ensure the provision of Alternative, Safe & ‘Intuitive’ Evacuation Routes for ALL building users.
Fully understanding the different functions of firefighters … and giving proper consideration to their safety … why aren’t Alternative, Safe and ‘Intuitive’ Fire Attack Routes for Firefighters provided, as the norm, in buildings ?
What is ‘Intuitive and Obvious’ Design for Fire Evacuation, anyway ?
Are Architects and Fire Engineers given any education or training about …
