2019-12-21:  Grenfell Inquiry Recommendations (2) – Fire Emergency Plans !

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 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, accurate and accessible fire emergency warning system must be installed, and such a system must always have a fire protected electrical supply.

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.

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 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 EMERGENCY

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:

  1. 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 ;
  2. 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 ;
  3. 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.

Colour image showing a range of personal Facilitation / Mobility Aids.  People with Activity Limitations must be allowed, and positively encouraged, to keep these Aids during practice and real fire evacuations.  Prior meaningful consultation (see below) is essential.  Click to enlarge.

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.

Fire Safety for All – Regional Implementation Model (Asia Pacific)

2019-10-21:  Following the very successful Rehabilitation International Asia-Pacific (AP) Conference in Macau, at the end of June 2019 … https://www.rimacau2019.org/ … I was invited by the United Nations Economic & Social Commission for Asia and the Pacific (UNESCAP – https://www.unescap.org/) to submit an Article on ‘Fire Safety for All’ to one of their upcoming publications.

Fire Safety for All … for vulnerable building users, including people with disabilities, young children, frail older people, people with health conditions, and women in late-stage pregnancy … is a critical component of Accessibility & Usability for All … the key factor in facilitating full social participation and inclusion.

Consistent with the philosophy and principles of Sustainable Human & Social Development, a concept which continues to evolve with robust resilience (despite many challenges) … and the 2015-2030 Sustainable Development Framework Agenda … implementation is most effective if carried out at Regional Level … adapted to a Local Context.

Full and effective implementation, in each separate jurisdiction, then requires:

  • a robust legal base ;
  • determined political will to implement ‘fire safety for all’ ;
  • sufficient public financial resources for implementation – ‘fire safety for all’ is a social*, as distinct from a human, right ;
  • a compassionate and understanding bureaucracy, at all institutional levels ;
  • competent spatial planners, architects, structural engineers, fire engineers, quantity surveyors, technical controllers, industrial designers, building/facility managers, and crafts/trades people at all levels in construction organizations ;
  • independent monitoring of ‘fire safety for all’ performance – self-regulation is NO regulation ;
  • innovative, well-designed fire safety related products, systems and fittings which can be shown to be ‘fit for their intended use’.

[ *Social Rights:  Rights to which an individual person is legally entitled, e.g. the right to free elementary education [Art.26(1), UDHR], but which are only exercised in a social context with other people, and with the active support of a competent legal authority, e.g. a nation state.

Commentary:  In contrast to human rights, it is not protection from the state which is desired or achieved, but freedom with the state’s help.]

If Policy and Decision Makers are serious, therefore, about meeting the Safety Needs of Vulnerable People in Fire Emergencies … This Is An Absolutely Minimum Threshold Of Practical Action To Bring About Urgent Change …

Article for UNESCAP

Fire Safety for AllNobody Left Behind !

The rising 21st Century Cities of the Asia-Pacific Region each encompass:

  1. a) an interwoven, densely constructed core ;
  2. b) a very large and widely diverse resident population ;
  3. c) a supporting hinterland of lands, waters and other natural resources ;

together functioning, under the freedoms and protection of law, as …

  • a complex living system ; and
  • a synergetic community capable of providing a high level of social wellbeing* for all of its inhabitants.

[ *Social Wellbeing for All:  A general condition – for every person in a community, society or culture – of health, happiness, creativity, responsible fulfilment, and sustainable development. ]

Colour photograph showing one of the oldest districts in Hong Kong … Sheung Wan … very high-rise development, with mixed commercial and residential activity.  Click to enlarge.  Photograph taken by CJ Walsh.  2019-06-24.

In all areas of life and living in this City Community, every person is equal before the law and is entitled, without any discrimination, to equal protection of the law*.  When they are in a building, for example, all of its occupants and users have an equal right to feel ‘fire safe’ as required by law.  This must also include vulnerable building users, particularly people with disabilities.

[ *Refer to Article 12 in the 2006 United Nations Convention on the Rights of Persons with Disabilities, which has been ratified by nearly every country in the world, including the European Union … and Article 7 in the 1948 Universal Declaration of Human Rights.]

Current national building codes – where they exist – do not protect vulnerable people in fire emergencies: many countries have no legal provisions answering this crucial need, while a small group of countries offer only token, i.e. inadequate, protection.  An ethical*, technical response is urgently required, therefore, at regional level in Asia-Pacific.  The social, political and institutional challenges blocking effective implementation are immense.

[ *Refer to the 2016 Dublin Code of Ethics: Design, Engineering, Construction & Operation of a Safe, Resilient & Sustainable Built Environment for All.  Download from: www.sfe-fire.eu ]

Note:  A Regional Implementation Strategy is already in the course of being developed for Asia-Pacific (AP).

Colour image illustrating the two concepts of social ‘equality’ and ‘equity’ … and, most importantly, the difference between the two.  Mainstream society must fully accept these concepts … and understand how, in order to achieve equality, the process of implementation must be equitable.  Click to enlarge.

Fire Safety for All … for vulnerable building users, including people with disabilities, young children, frail older people, people with health conditions, and women in late-stage pregnancy … is a critical component of Accessibility & Usability for All … the key factor in facilitating full social participation and inclusion.  This design objective is achieved by equitable fire prevention and fire protection measures, essential occupant/user practices, independent fire evacuation procedures, proactive management and, as a last but necessary resort, reliable assisted evacuation and/or firefighter rescue.

In the Smart City, nobody must be left behind !

During the first critical 10-15 minutes in a fire emergency – the time between when a fire is first accurately detected, warnings are transmitted, and firefighters arrive at the building – many people with disabilities are more than capable of independent evacuation using reliably functioning lift/elevator fire evacuation assemblies.  Independent use of lifts/elevators by people with disabilities is essential during a fire emergency … and must be facilitated.

The enormous benefit for those vulnerable individuals who are capable of negotiating horizontal and vertical circulation routes by themselves is being able to evacuate a building and reach a ‘place of safety’ in the company of other building occupants/users.  They remain independent, in control of their own evacuation, and able to leave without waiting for someone else to rescue them or render assistance.

Buildings must remain structurally ‘serviceable’ until all building occupants/users and firefighters have reached a remote ‘place of safety’.

Management systems and fire protection measures in buildings are never 100% reliable.  People with disabilities must, therefore, be trained to be self-aware in situations of risk, particularly in fire emergencies, and actively encouraged to develop the skills of self-protection and adaptive self-evacuation.

Essential Features At Building Design Stage

Fire Safety for All must be carefully considered at the initial stages of building design.  To be effective, however, the following essential passive and active fire protection measures must be incorporated in buildings …

A.  A smart ‘whole building’ fire emergency detection and multi-format warning system is an essential fire safety feature in all building types, new and existing. Vulnerable building occupants/users need much more time to react, and evacuate, than other users during a fire incident.

B.  All building occupants/users must be provided with alternative, intuitive and obvious evacuation routes away from a fire outbreak in a building. A significant number of building users will never pass through the smoke generated by fire.

C.  All fire evacuation routes in a building must be accessible for building occupants/users, and be sufficiently wide to accommodate contraflow, i.e. building users evacuating while firefighters enter the building at the same time. Under no circumstances must ‘stay put’ policies be normalized, or practiced.

D.  Phased horizontal evacuation must be facilitated, in design, by providing ‘buffer zones’ around fire compartments, and adjacent ‘places of relative safety’.

E.  All lifts/elevators in a building must be capable of being used during a fire emergency. This is already the case, in most countries, with firefighter lifts.

F.  Fire protected evacuation staircases must be sufficiently wide (1.5m between leading handrail edges) to facilitate contraflow and the assisted evacuation of manual wheelchair users; they must open into fire protected lift/elevator lobbies at every floor/storey level, and open directly to the exterior at ground level.

Colour photograph showing the ‘contraflow’ circulation which must be facilitated during a fire emergency … as building occupants/users evacuate away from the fire towards a place of safety located a remote distance from the building … while heavily equipped firefighters are able to enter the building, unhindered, at the same time.  This ensures that firefighters can quickly locate people waiting in areas of rescue assistance and lift/elevator lobbies.  Click to enlarge.

G.  Sufficiently large, fire protected ‘areas of rescue assistance’, where people can safely wait during a fire emergency, must adjoin each evacuation staircase on every floor/storey above ground level. When calculating space provision for evacuation and waiting areas in buildings, the minimum reasonable provision for people with disabilities must be 10% of the design building occupant/user population; for people with activity limitations, minimum space provision must rise to 15% of the design occupant/user population.

Colour illustration of a sufficiently wide fire evacuation staircase, which will accommodate contraflow and the assisted evacuation of people in wheelchairs … with a sufficiently large, directly adjoining ‘area of rescue assistance’ … which will accommodate people unable to independently evacuate during a fire emergency.  The space provided in an area of rescue assistance, on each floor/storey, is calculated in relation to the design occupant/user population of a building.  Even if a building is fully sprinklered, an area of rescue assistance must adjoin every fire evacuation staircase.  Click to enlarge.  Staircase design by CJ Walsh.

Image of text showing the definition for ‘people with activity limitations’, with its equivalent French translation … also showing from where this term is derived … and who this term includes.  During a fire emergency, confused and/or confusing disability-related language costs lives !  Click to enlarge.

H.  Such is the universal level of fire compartment unreliability, that lift/elevator lobbies and ‘areas of rescue assistance’ must be fitted with an active fire suppression system, i.e. water mist … an environmentally clean suppression medium which is person-friendly, and will not greatly interfere with visibility.

I.  In tall, super-tall and mega-tall buildings, every 20th floor/storey must be an accessible ‘floor of temporary refuge’ … and the roofs of those buildings must be capable of being used for aerial evacuation.

J.  In health care facilities, e.g. hospitals, the fire safety strategy must always be to ‘protect in place’. Patient evacuation is highly hazardous, and unacceptable.

K.  Fire defence plans* must demonstrate a proper consideration for the fire safety, protection and evacuation of all building users/occupants, with a particular and integrated focus on people with activity limitations.

[ *Fire Defence Plan:  A pre-determined and co-ordinated use of available human and material means in order to maintain an adequate level of fire safety and protection within a building and, in the event of an outbreak of fire, to ensure that it is brought speedily under control and extinguished … with the aim of minimizing any adverse or harmful environmental impacts caused by the fire.

Commentary 1:  A Fire Defence Plan is developed for a specific building at design stage.  It later becomes the basis for an occupied building’s Fire Emergency Management Plan.

Commentary 2:  A Fire Defence Plan is usually in electronic format and/or hard copy and comprises fire engineering drawings, descriptive text, fire safety related product/system information, with supporting calculations, and the fire test/approval data to demonstrate ‘fitness for intended use’.]

SFE Work Programme 2017 – Want To Get Involved & Help ??

2017-01-05:  Happy New Year to All and One !

SUSTAINABLE FIRE ENGINEERING (SFE)

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 ;

  • people who are visually and/or hearing impaired ;

  • 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.

SUSTAINABLE FIRE ENGINEERING (2017)

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.

Would you like to get involved, and help with this work ?

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.

Progress with this work can be followed here: http://www.fire-safety-for-all.sustainable-design.ie/iso-21542/

The next ISO Meeting will take place in Madrid, Spain … towards the end of March 2017.

‘Sustainable Accessibility for All’ – An SDI Professional Service

2012-11-30:  Related specifically to my 2 Previous Posts on 27 November 2012 & 28 November 2012 … this is how we would like to help you … whether you are an individual, or an organization … whether you are located in Ireland, Italy or Turkey … some other part of Europe, the Arab Gulf Region, India, Japan, China … or wherever !

And … we can, if requested or necessary, work in collaboration with local partners in those different geographical regions.

Introduction

For many Weak and Vulnerable People, today’s Complex Human Environment is inaccessible and unsafe … a hostile ‘reality’ which prevents independent functioning and participation in a local community;  it is a blatant denial of their human rights.

Restrictions on Social Participation, e.g. physical barriers, sloppy user-unfriendly management procedures, discrimination, stigma, etc … also limit the Use Potential of buildings, transportation systems, public spaces and other facilities … shortening product life cycles.

These factors impose a large, negative cost burden on society generally … and on you, as an individual … or as an organization, whether private or public.  It is bad business !

‘Sustainable Fire Engineering’ – Important Indian Presentation !

2009-09-08:  It is really enjoyable to be back behind my desk, here in Dublin.  Apologies for the prolonged absence.

Since the middle of June last, my travels have taken me to Turkey, France, Italy, the south-west of Ireland to attend my cousin’s wedding in Cork … and back again to Bengaluru (Bangalore) in Southern India to make an important Keynote Presentation at the 2009 Fire & Safety Association of India (FSAI) National Fire Seminar: ‘Engineering a Safe & Secure India’, which was held on Friday, 28th August, at the Leela Palace Hotel.

My Presentation Title & Abstract

Sustainable Fire Engineering: Fire Safety, Protection & Evacuation for All

India, like other economically advanced developing countries, is at an important crossroads.  Difficult, resource-dependent decisions must be made in the next few short years concerning the rapid implementation of a Sustainable Built Environment across a vast country, i.e. one which must serve local needs and meet regional performance requirements during a long life cycle … one which will be adaptable to climate change, variability and extremes … will be in harmony and dynamic balance with the Natural Environment … and, not least, will be super energy-efficient.

Citizens of Developed Nations also have legitimate expectations.  They will express anger when they witness recently constructed buildings in seismic zones collapse, in an earthquake, like a deck of cards (China 2008, Italy 2009) … or they discover that federal/state authorities having jurisdiction, which are funded by their taxes, are ill-prepared to respond effectively to intentional traumatic disruptions to the Social Environment (New York 2001, Mumbai 2008).  Retaining the public’s confidence in national institutions is a fundamental political priority.

In the case of all new High-Rise Buildings, Iconic Buildings, and Buildings of Innovative Design or having a Critical Function … Trans-Disciplinary Building Design Teams must, at a minimum, properly respond to the Recommendations of the 2005 & 2008 NIST(USA) Final Reports on the 9-11 WTC 1, 2, and 7 Collapses.  In practice, the majority of these Recommendations should be applied to the design of all new buildings !

Fire Engineers, competent concerning the processes of ‘real’ building design and construction, must begin to understand the ‘real’ people who occupy or use buildings, every day of every week, in all parts of India … and that they each have widely differing ranges of human abilities and activity limitations.  Just as they are different from each other, they will react differently than expected in a ‘real’ building fire emergency.

Based on a Keynote Presentation before International Council for Building Research (CIB) Working Commission 14 : Fire and Sub-Committee 3 & 4 Members of ISO Technical Committee 92 : Fire Safety, at Lund University in Sweden … and his fire safety texts which have been fully incorporated into International Standard ISO DIS 21542 on Accessibility-for-All, currently under development and due for publication before the end of 2010 … CJ Walsh’s Presentation, at the FSAI National Fire Seminar in Bengaluru, will focus on ‘Fire Safety, Protection & Evacuation for All’.
