2016 Dublin Code of Ethics – Design, Engineering, Construction & Operation of a Safe, Resilient & Sustainable Built Environment for ALL

2020-09-22:  Adopted at SFE 2016 DUBLIN (www.sfe-fire.eu) …

Many years have passed since the 1972 UN Stockholm Declaration on the Human Environment and the 1992 Rio Declaration on Environment and Development.  In 2016, Sustainable Development remains an intricate, open, dynamic and continually evolving concept.  The guide and driver for frontline practitioners, policy and decision makers must be a personal Code of Ethics … an integrated and inter-related whole which cannot be reduced to fixed rules inviting game playing and ‘trade-offs’.  After working with this Code, it may be necessary to expand on and discuss its principles and/or some of the issues raised … not to narrow its focus, but to broaden interpretation.

.

CODE APPLICATION & PURPOSE

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 !

SDI’s 2020 Unified Terminology – Concepts, Terms & Definitions

Update 2020-09-01:  Although the term ‘Vulnerable People’ remains unaltered, I considered it wise, and very necessary bearing in mind the obvious myopia in the mainstream health, safety and design worlds … clearly demonstrated by the 2017 Grenfell Tower Fire in England, and this current CoronaVirus / CoVID-19 Global Pandemic … to include references to specific social groups …

Vulnerable People:  Those people – in a community, society or culture – who are most at risk of being physically, psychologically or sociologically wounded, hurt, damaged, injured, or killed … and include, for example, people with disabilities, young children, people with health conditions, frail older people, women in late pregnancy, refugees, migrants, prisoners, the poor, and homeless.

.

2020-07-20:  So many diverse design disciplines and interested groups are involved in the realization, operation and maintenance of a Safe, Inclusive, Resilient and Sustainable Human Environment (built, social, economic, virtual, and institutional) … that the use of simple, easily assimilated language and precise, harmonized technical terminology must be widely exercised.  For the effective application of Building Information Modelling (BIM), this is particularly important.

And concerning Fire Engineering, it is not clear when the practice began, but defining a concept simply in terms of performance in a ‘standard test fire’ is entirely inadequate, and fails to explain the actual meaning of the concept.

..

SDI’s 2020 Unified Terminology – Concepts, Terms & Definitions   (Download PDF File, 156 Kb)

.

This Terminology … a body of particular terms, each explaining and defining a single concept, covering inter-related building requirements, e.g. human health, accessibility and fire safety for all, firefighting, social rights, design, performance monitoring, and facility management … takes account of:

  1. Sustainability Impact Assessment (SIA)
  2. WHO International Classification of Functioning, Disability and Health (ICF)
  3. Universal Declaration of Human Rights (UDHR)
  4. U.N. Convention on the Rights of Persons with Disabilities (CRPD)
  5. Environmental Impact.

Fire Engineering Terms … take account of the ‘realistic’ end condition, i.e. a real fire in a real building which is occupied or used by real people with varying behaviour and 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.

General Terms … are also included in order to facilitate a better understanding of:

  • the complexity of human behaviour and perception (visual, auditory, olfactory, gustatory, tactile and proprioceptive) ;
  • the wide range of health conditions ;   and, more specifically
  • mental, cognitive and psychological impairments.

2015 Dublin Declaration on ‘Fire Safety for All’ in Buildings – A Call to Action and Successful Implementation !

2015 Dublin Declaration on ‘Fire Safety for All’ in BuildingsA Call to Action and Successful Implementation !   (Download PDF File, 106 Kb)

.

Within the professional discipline of Fire Engineering … either a building is Fire Safe, or it is not ;  the design philosophy of the Fire Engineer is irrelevant.  Similarly, building designers must now begin to think and act in the simple terms of a building being either Accessible, or not.  Too many pointless discussions, and too much petty squabbling, about constrained and constraining accessibility philosophies have wasted valuable time, energy and resources.

Reality Check: A Universal, Dismally Inaccessible Built Environment !

.

Building Accessibility encompasses the complete cycle of Independent Use, in a dignified manner and on an equal basis with others … and includes the approach, entry and use of a building, its facilities and information systems … Egress during normal / ambient conditions and removal from the vicinity of the building … and most importantly, safe Evacuation during a fire emergency to a Place of Safety which is remote from the building and reached by way of an accessible route.

.

Human Ability and Behaviour is a continuum … a gentle gradient on which every person functions and acts at different levels due to Environmental and Personal Factors.
.

.

To be Accessible, a building must meet a long and complex list of inter-related Accessibility & Usability Design Criteria sufficiently well, i.e. the building must work properly for building occupants and users.  The design target is Effective Accessibility … not half-baked accessibility, partial accessibility, the minimal accessibility required by building codes, or token accessibility.

On the other hand, and taking additional account of the current CoronaVirus / CoVID-19 Pandemic … the construction and operation target must be Successful Implementation, i.e. the finished building design, as constructed and operated, must provide a consistently high degree of safety, convenience and comfort for potential occupants and users during the lifetime of the building.

.

People with Activity Limitations … those people, of all ages, who are unable to perform, independently and without assistance, basic human activities or tasks – because of a health condition or physical / mental / cognitive / psychological impairment of a permanent or temporary nature … are a significant vulnerable group in every community, in every society, and include people with disabilities, children under the age of 5 years, frail older people, women in the later stages of pregnancy, and people with health conditions, etc.

Fire Safety Codes and Standards for healthy, able-bodied, agile adults using buildings exist in almost every country ;  these people can take for granted that buildings are fire safe for them !

However, guidelines concerning Fire Safety for People with Activity Limitations / Fire Safety for ALL (if those guidelines exist at all) are usually technically inadequate, entirely tokenistic and/or blatantly discriminatory ;  these people must assume that there is a serious risk to their safety every time they enter a building.  For them, this is a very significant barrier to their personal development, participation and social inclusion ;  it is a clear and present violation of their human rights !

Forcefully mandated in the United Nations Convention on the Rights of Persons with Disabilities, adopted on 13 December 2006 … the UN CRPD’s Principal Aim is to ensure that the Human Environment (social, built, economic, virtual, and institutional) is sufficiently accessible to facilitate the safe exercise and enjoyment of those rights, protections and freedoms set down in the 1948 Universal Declaration of Human Rights (UDHR), and subsequent International Rights Instruments, by a vulnerable and major section of the population in all of our communities.

.
A serious design flaw in this building (among many, many others), i.e. a lack of Effective Accessibility … only one narrow, atrociously detailed staircase serving the entire building, lifts/elevators which were useless in a fire emergency, and no areas of rescue assistance adjoining the staircase … had a profoundly negative impact on Firefighter Operations and Safety on the night of 14 June and the following day.

It is time to Entirely Eradicate current obsolete, professionally negligent, incompetent and ridiculous approaches to Building Design which result in …

Fire Safety for SOME but not for ALL

Accessibility for SOME but not for ALL

Intricately inter-related … ‘Fire Safety for All’ is a vital component of ‘Accessibility for All’.

2004 Rio de Janeiro Declaration on Sustainable Social Development, Disability & Ageing

2020-04-28:  A look back at a Benchmark Document, and an Introduction written nearly 16 years ago.  So many years, so much valuable time has been wasted …

..

2004 Rio de Janeiro Declaration on Sustainable Social Development, Disability & Ageing  (Download PDF File, 306 Kb)

The words ‘green’, ‘environmental’, ‘ecological’ and ‘sustainable’ are becoming part of everyday language in the Developed World, but are frequently interchanged without understanding.  To date, however, the concept of Sustainable Development has been hijacked by Environmentalists.  For example, no connection at all may be seen between a ‘sustainable’ building and ensuring that it can be safely and conveniently entered and used by ordinary people.

In other parts of the World, the ambiguous WCED / Brundtland Definition of Sustainable Development is being systematically rejected ;  the concept is viewed as an unaffordable luxury and/or as a means of continued domination and control by the ‘North’.  Yet, sustainability must be a global compact.

In this intolerant and more fundamentalist 21st Century, the United Nations System, International Law, and Social Justice continue to come under sustained attack.  And the Beslan School Tragedy* demonstrates that it is far more hazardous for disadvantaged, vulnerable and indigenous peoples in every society.

[ * The 2004 Beslan School Massacre … https://en.wikipedia.org/wiki/Beslan_school_siege … and its commemoration 10 years later … https://www.rt.com/news/183964-beslan-school-hostage-crisis/ ]

Some specific objectives for the 2004 Rio Declaration were as follows …

  • To present a 2nd Generation Definition of Sustainable Development which is more acceptable to the Developing World ;
  • To restore primacy to the Social Aspects of Sustainable Development … and particularly the ethical values of Social Justice, Solidarity and Inclusion-for-All ;
  • To embed the concept of the ‘Person’ in Sustainable Development … rather than the fleeting reference to ‘People’ which too often results in Disadvantaged, Vulnerable and Indigenous Groups being left behind ;
  • To signal one of the main challenges of Sustainable Development ahead – which will be to establish a framework of horizontal co-ordination at the many institutional levels … and between the many actors and end users … in the human environment.

Adopted in December 2004, at the Brazil Designing for the 21st Century III Conference, the Rio Declaration consists of a Preamble, 10 Principles and 5 Appendices ;  its central concern involves People with Activity Limitations (2001 WHO ICF).

This Declaration extols implementation, and the targeting and monitoring of ‘real’ performance – as opposed to ‘imagined’ or ‘paper’ performance.

Grenfell Inquiry Recommendations (3) – Fire Alarms !!

Previous Posts In This New Series …

2019-10-31:  Grenfell Tower Fire Inquiry’s Phase 1 Report – Information

2019-11-11:  Grenfell Inquiry Recommendations (1) – Vulnerable People ?

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 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.

Colour photograph showing a single combined visual-audible Fire Emergency Warning Device.  Click to enlarge.

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.

Colour image showing the movement of building occupants and users.  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:

  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.

.

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.

After Grenfell: Reliable Design, Supply & Construction Essential !

2017-10-10:  After the Grenfell Tower Fire Tragedy in London, on 14 June 2017, the integrity of the English Regulatory and Technical/Building Control Systems is now so compromised that a complete Systems Transformation is immediately required !   Closer to home, here in Ireland … what nobody is daring to say, even our tame media, is that Our Regulatory System is based very closely on the English System.  And Our Technical/Building Control System is purposefully under-resourced … so it is weak and ineffective.

Let there be no confusion … Priory Hall and Longboat Quay, both in Dublin, are just the tip of an enormous iceberg …

So where do we start again ?

Reality – Reliability – Redundancy – Resilience !

With regard to Reliable Fire Engineering Related Design, Supply and Construction … this is how we must proceed …

  1. Design of the works is exercised by an independent, appropriately qualified and experienced architect/engineer/fire engineer, with design competence relating to the fire protection of buildings ;
  1. Supply of fire safety related construction products/systems to the works is undertaken by reputable organizations with construction competence, particularly in relation to the fire protection of buildings ;
  1. Installation/fitting of fire safety related construction products/systems is exercised by appropriately qualified and experienced personnel, with construction competence relating to the fire protection of buildings ;
  1. Supervision of the works is exercised by appropriately qualified and experienced personnel from the principal construction organization ;
  1. Regular inspections, by appropriately qualified and experienced personnel familiar with the design, and independent of both the design and construction organizations, are carried out to verify that the works are being executed in accordance with the design.

Firefighter Safety & Solar Photovoltaic Panels On Buildings ??

2016-09-14:  Only now are we really catching up with the extremely serious matter of Fire Safety in Sustainable Buildings … serious for building occupants … and firefighters !

‘ In order to achieve sustainable development, environmental protection and energy efficiency/conservation shall constitute integral parts of the development process, and shall not be considered in isolation.’

2016 Dublin Code of Ethics: Design, Engineering, Construction & Operation of a Safe, Resilient & Sustainable Built Environment for All   ( www.sfe-fire.eu )

The Performance Target for New Construction must be Positive Energy Buildings.

So … we will see more and more Solar Photovoltaic Panels installed on more and more buildings … in every country.  Certainly not less !   And, let’s face it, many will not be properly approved, i.e. shown to be ‘fit for their intended use’ …

At the beginning of this decade, a Fire Research Project was carried out by the Underwriters Laboratories Firefighter Research Institute in the USA … and it addressed the issue of firefighter vulnerability to electrical hazards, and serious injury, when fighting a fire involving Solar Photovoltaic (PV) Modules and Support Systems installed on buildings.

The Total Global Solar Energy Capacity averaged 40 % annual growth from 2000 to 2010 (source: International Energy Agency).  In the USA, Grid-Connected Solar Photovoltaic Capacity grew 50 % per year for much of that time (source: US Federal Energy Regulatory Commission).  These trends increase the potential of a Fire Service Response to a building having a Photovoltaic Installation, irrespective of the PV being involved with the initiation of the fire event.  As a result, conventional firefighter tactics for suppression, ventilation and overhaul have been complicated, leaving firefighters vulnerable to potentially unrecognized exposure.  Though the electrical and fire hazards associated with electrical generation and distribution systems are well known, PV Systems present unique safety concerns.  A limited body of knowledge and insufficient data exist to understand these risks … to the extent that Fire Services have been unable to develop safety solutions and respond in a safe manner.

This Fire Research Project developed the empirical data needed to quantify the hazards associated with PV Installations … and provided the foundation to modify current or develop new firefighting practices to reduce firefighter deaths and injury.

The Tactical Considerations addressed during the Project include:

  • Shock hazard due to the presence of water and PV power during fire suppression activities ;
  • Shock hazard due to the direct contact with energized components during firefighting operations ;
  • Emergency disconnect and disruption techniques ;
  • Severing of conductors ;
  • Assessment of PV power during low ambient light, artificial light and light from a fire ;
  • Assessment of potential shock hazard from damaged PV Modules and Systems.

UL Report (2011):  The Following Summarizes the Findings of This Fire Research Project:

  1. The electric shock hazard due to the application of water is dependent on voltage, water conductivity, distance and spray pattern.  A slight adjustment from a solid fire hose stream towards a fog pattern (10 degree cone angle) reduced measured current below perception level.  Salt water should not be used on live electrical equipment.  A distance of 6 m has been determined to reduce potential shock hazard from a 1000 VDC source to a level below 2 mA, considered as safe.  It should be noted that pooled water or foam may become energized due to damage in the PV System.
  1. Outdoor weather exposure-rated electrical enclosures are not resistant to water penetration by fire hose streams.  A typical enclosure will collect water and present an electrical hazard.
  1. Firefighters’ gloves and boots afford limited protection against electrical shock provided the insulating surface is intact and dry.  They should not be considered equivalent to Electrical Personal Protective Equipment (PPE).
  1. Turning off an array is not as simple as opening a disconnect switch.  Depending on the individual system, there may be multiple circuits wired together to a common point such as a combiner box.  All circuits supplying power to this point must be interrupted to partially de-energize the system.  As long as the array is illuminated, parts of the system will remain energized.  Unlike a typical electrical or gas utility … on a PV Array, there is no single point of disconnect.
  1. Tarps offer varying degrees of effectiveness to interrupt the generation of power from a PV Array, independent of cost.  Heavy, densely woven fabric and dark plastic films reduce the power from PV to nearly zero.  As a general guide, if light can be seen through a tarp, it should not be used.  Caution should be exercised during the deployment of tarps on damaged equipment, as a wet tarp may become energized and conduct hazardous current if it contacts live equipment.  Also, firefighting foam should not be relied upon to block light.
  1. When illuminated by artificial light sources, such as Fire Department light trucks or an exposure fire, PV Systems are capable of producing electrical power sufficient to cause a lock-on hazard.
  1. Severely damaged PV Arrays are capable of producing hazardous conditions ranging from perception to electrocution.  Damage to the array may result in the creation of new and unexpected circuit paths.  These paths may include both array components (module frame, mounting racks, conduits, etc) and building components (metal roofs, flashings and gutters).  Care must be exercised during all operations, both interior and exterior.  Contacting a local professional PV Installation Company should be considered to mitigate potential hazards.
  1. Damage to modules from tools may result in both electrical and fire hazards.  The hazard may occur at the point of damage or at other locations depending on the electrical path. Metal roofs present unique challenges in that the surface is conductive unlike other types such as shingle, ballasted or single ply.
  1. Severing of conductors in both metal and plastic conduit results in electrical and fire hazards.  Care must be exercised during ventilation and overhaul.
  1. Responding personnel must stay away from the roofline in the event of modules or sections of an array sliding off the roof.
  1. Fires under an array but above the roof may breach roofing materials and decking … allowing fire to propagate into the attic space of the building.
