2024-10-06: After reading the Grenfell Tower Inquiry Phase 1 Recommendations (Chapter 33) … I was naturally curious about what would be happening during the next phase. Paragraph 34.14 in Chapter 34, however, struck me as strange, even unbelievable … the single narrow #Stairs in the Tower would NOT be the subject of further investigation in Phase 2..
This is the Ridiculous Single Narrow Fire Evacuation Staircase in the High-Rise Residential Grenfell Tower …
Although the Grenfell Tower Inquiry Phase 2 Recommendations (Chapter 113) concluded by looking back to Phase 1, and specifically mentioning Personal Emergency Evacuation Plans (#PEEP) … nothing was said about the Fire Evacuation Staircase. Case closed. And there is only one word to describe this outcome: ‘FUBAR’ !
Struggling to understand that highly questionable decision … a deep dive into the Phase 1 ‘Expert’ Technical Evidence led me to this Page from Report BLAS0000019, dated 2018-10-24 …

Three Important Documents Relevant To Competent Fire Evacuation Staircase Design :
Orientation Manual for First Responders on the Evacuation of People with Disabilities, Document FA-235 / August 2002, published by the Federal Emergency Management Agency (#FEMA) in the #USA. Yes indeed, this document was published way back in 2002, and is still freely available on the Internet.
A vital piece of information with regard to the Firefighter’s Lift, and the serious harm which can be inflicted on People with Disabilities by its use …
In the absence of an operable Lift/Elevator Fire Evacuation Assembly in a building … which is still usually the norm … this photograph provides vital information with regard to the Correct, Best and Least Hazardous Method of assisting the evacuation of a person using a Manual Wheelchair. Electric wheelchairs are too heavy, and too awkward in shape, to be lifted down/up a Fire Evacuation Staircase, even with three sturdy individuals assisting. Note that some elaborate, highly-adapted and very expensive manual wheelchairs cannot facilitate being lifted. In all cases, however, Vulnerable People requiring Mobility Aids will be most reluctant to leave them behind in an emergency … and they MUST be allowed to keep their personal aid.

Final Report on the Collapse of the World Trade Centre Towers 1 & 2 (on 2001-09-11), Document NIST NCSTAR 1 / September 2005, published by the National Institute of Standards & Technology (#NIST) in the USA. Refer to Recommendation 17 on pages 215 and 216.
[ Contraflow Circulation, in a Fire Building: 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. ]
Contraflow Circulation during a Fire Emergency is essential. This facilitates rapid and safe movement of firefighters towards Fire Protected Lift/Elevator Lobbies and Areas of Rescue Assistance in order to check on the presence, or otherwise, of Vulnerable People who may be waiting for rescue.
Once Firefighters enter a Fire Building … and without provision for #Contraflow Circulation … the ordering of a ‘Stay Put’ Policy for building occupants is the only difficult option … but this is NO LONGER ACCEPTABLE.
Carefully examine the photograph below. Firefighters wearing heavy protective clothing and also carrying firefighting equipment require far, far more circulation width than 510 mm !! However, this staircase is still not wide enough to facilitate unhampered building user evacuation. Notice how people have to twist sideways in order to allow firefighters to pass … and this inevitability slows down evacuation progress in the ‘real’ world.
.
International Standard ISO 21542: Building Construction – Accessibility & Usability of the Built Environment, published in 2011 and revised in 2021. Standardizes good design for accessibility and the safe usability of buildings, which has been common practice for many decades.
Basics Of Staircase Design … Going, Rise, and Height of Handrails … ON BOTH SIDES of every flight of stairs …
Basics Of Staircase Design … Clear Unobstructed Width – Between 2 Continuous Handrails. ALL Fire Services MUST adopt this single understanding of ‘clear unobstructed width’ of a staircase !
Basics Of Staircase Design … Staircases pose a serious hazard, especially during the stressful process of Emergency Evacuation … HAZARD Tactile Walking Surface Indicators (stippled, for hazard) at the TOP and BOTTOM of every flight of stairs. Concerning this particular design issue, British Standards and English Building Regulations MUST be ignored !
Basics Of Staircase Design … Handrail Tactile Plates, essential for the evacuation information to be used by people with a visual impairment in an emergency. Refer to Figure 38 in ISO 21542. However, this is a much more informative photograph … from one of my previous visits to Japan. Notice the high colour contrasting …
Basics Of Fire Evacuation Staircase Design … The Clear Unobstructed Width of 1.50 metres between Continuous Handrails on a Fire Evacuation Staircase facilitates Contraflow Circulation, the Safe Assisted Evacuation of People in Manual Wheelchairs, and Stretcher Evacuation of Building User and/or Firefighter Victims during an emergency.
.
CONCLUSIONS
Having been directly involved in the drafting of national and international Accessibility Standards and Technical Guidance since the 1980’s … I am really, really annoyed by the inept and incompetent misuse of raw anthropometric data to try to justify the width of this sorry excuse for a Fire Evacuation Staircase in the Grenfell Tower … and inflicting the Firefighter’s Lift/Carry on People with Disabilities is NOT ACCEPTABLE. This shoddy ‘expert’ evidence clearly demonstrates a profound ignorance of Building Design, and about how ‘real’ people use ‘real’ buildings.
My great fear is that the technical justification for this shambolic fire evacuation staircase will become a benchmark for similar shambolic staircases in other buildings … not just in England, but in other jurisdictions who are dim-witted enough to copy England’s bad example … whatever it does.
Professional building design, construction and technical control disciplines, who practice in England, MUST carefully read … and keep re-reading, as necessary … Paragraph 113.12 in the Grenfell Tower Inquiry Phase 2 Report … which is expressed in too mild a form for my liking …
Our investigations have shown that levels of competence in the construction industry are generally low and that by the time of the Grenfell Tower fire many contractors, designers and building control officers treated the Statutory Guidance as containing a definitive statement of the legal requirements. It is understandable that those who turn to the Guidance for advice about how to comply with the Building Regulations should be tempted to treat it as if it were definitive … We therefore recommend that a revised version of the guidance contain a clear warning in each section that the legal requirements are contained in the Building Regulations and that compliance with the Guidance will not necessarily result in compliance with them.
I must go further … where the Technical Guidance in any of the English Approved Documents is known to be inadequate, or even suspect, it is the ethical duty and responsibility of a true professional to find a better way of complying with the relevant Functional Requirements in Building/Fire Regulations.
In addition, and specifically in relation to Building Fire Safety … it is necessary, at the same time, to comply with ALL of the relevant Functional Requirements in England’s Building Regulations … that means NOT ONLY WITH REQUIREMENT B … BUT ALSO WITH REQUIREMENTS A, K & M (for a start) ! The recent publication of a single document which merges ALL of the Approved Documents is a small step in the right direction of improving a deeply flawed body of building legislation.

Competent Building Design / Ethical Building Design … Lies Beyond Codes !!
2024-09-14: Inclusive Accessibility of the Built Environment – ‘Accessibility for All’ – is a dynamic, continuously evolving concept … the effective implementation of which is essential if we are to realize a Safe, Resilient and Sustainable Built Environment … for ALL, i.e. including everybody, every ‘Person’ in society … particularly ‘Vulnerable People’.
Whether it’s People with Activity Limitations (2001 WHO ICF), or #Refugees, or #Migrants … how does ‘Inclusion’ differ from ‘Integration’ ?
.
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.
People with Activity Limitations (2001 WHO ICF) :
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.
Accessibility of a Building :
Encompasses the complete cycle of independent use of a building – in a dignified manner and on an equal basis with others – including the approach, entry and usability of the building and its facilities, services and information/communication systems, egress from the building during normal conditions and removal from its vicinity and, most importantly, evacuation during an emergency to a place of safety remote from the building and reached by way of an accessible route … by all of the building’s potential users, with an assurance of their health, safety, welfare and security during the course of those activities.
Successful Accessibility Implementation : [ Principle 2 – 2015 Dublin Declaration on ‘Fire Safety for All’ in Buildings ]
Successful Accessibility Implementation … meaning high quality accessibility performance in the built environment … is reliant upon:
A robust Legal Base mandating accessibility for all and fire safety for all ;
Determined Political Will ;
Sufficient public Financial Resources ;
A compassionate and understanding Bureaucracy at all levels ;
Competence … meaning duly educated, trained and experienced in accessibility and fire safety design … spatial planners, architects, structural engineers, fire engineers, quantity surveyors, technical controllers, industrial designers, building managers, and people at all levels in construction organizations ;
Independent Monitoring of accessibility and fire safety performance ;
Innovative, well-designed accessibility and fire safety related Products and Systems which can be shown to be ‘fit for their intended use’.
.
Accessible Train Toilet Room in Japan :

Principle 9 – 2004 Rio Declaration on Sustainable Social Development, Disability & Ageing :
Concerted and properly resourced programmes of #Disability and #Age Related education and training should be provided in every U.N. Member State … at all levels … to politicians, educationalists, bureaucrats, administrators, and technical personnel connected, directly or indirectly, with the spatial planning, design, construction/de-construction, operation, management and maintenance of the Human Environment – in order to ensure that the implementation and monitoring of disability and age related Sustainable Social Policies, and the requirements of International Law, are competent and effective.
The #Dignity, #Privacy, #Autonomy and #Independence of every #Person should be respected.
Every U.N. Member State should adopt measures for the production and management of national disability and age related #Statistics – within an agreed and harmonized international framework – which are impartial, reliable, objective, scientifically independent, and accessible to the Public.
For #Survival and #Liberation, the priority targets for a comprehensive range of disability and age related sustainable social policies should be …
– Residential Buildings ;
– Public Transport … including buses, coaches, taxis, trams, trains, ferries, ships and planes ;
– Educational Buildings ;
– Places of Work.
Good #Education, within a context of Lifelong Learning for All, and Good #Employment are important keys to Social Inclusion.
For #Health and #SocialWellbeing, the priority targets for a comprehensive range of disability and age related sustainable social policies should be …
– Health Facilities ;
– Electronic, Information & Communication Technologies (#EICT’s) ;
– Civic Buildings ;
– Existing Buildings & Infrastructure … of Historical, Cultural or Architectural Importance.
In the short term, properly resourced programmes of work should be carried out and monitored in all U.N. Member States – in order to ensure that the Human Environment (social, built, institutional and virtual) is effectively Accessible for All.
2020-09-22: Adopted at the International Fire Conference: 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.
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 !
2020-09-08: Ignoring Britain’s silly sabre-rattling, toothless threats and boorish blackmail attempts reported in the Media during this past weekend, yesterday and today … the actual state of play in the tortuous Brexit Negotiations can best be judged from the following sources …
Michel Barnier’s Presentation to the Institute for International and European Affairs (IIEA), on 2 September 2020 … View it Here on YouTube
This is the European Union (EU), a Single Market of approximately 450 Million consumers. The EU operates under the freedoms and protections of Codified / Written Law, i.e. EU Treaties ratified by all of the EU Member States, EU Secondary Legislation (Regulations and Directives), and EU Administrative Provisions.
.
A suite of EU Regulations and Directives covers Industrial Products. While there is some flexibility with regard to how Directives are implemented at national level in the Member States, no such flexibility exists with Regulations. Construction Products can only be placed on the EU Single Market if they can be shown to comply with the requirements of the EU’s Construction Products Regulation (CPR) Framework, or in other words, be shown to be ‘fit for their intended use’ in the European Union …
BREXIT ~ IMPLICATIONS FOR THE BRITISH FIRE INDUSTRY
Trade ‘No Deal’ or ‘Minimal Deal’ … from 1 January 2021, Great Britain will be completely outside the European Single Market, and the EU’s Construction Products Regulation Framework. The designation ‘Notified Body’ under that Framework will fall away from British Organizations. Construction Products/Systems manufactured in, or supplied from, Britain will then have to undergo an entirely new EU Testing and Approvals Programme in order to access the European Single Market. Fire Safety related Construction Products will have to be tested, and assessed or appraised, against all 7 Basic Requirements for Buildings together, during the same period of time (see Annex I, EU Regulation 305/2011) …
Mechanical Resistance and Stability
Safety in Case of Fire
Hygiene, Health and the Environment
Safety and Accessibility in Use
Protection against Noise
Energy Economy and Heat Retention
Sustainable Use of Natural Resources
… a process which will be very interesting to observe, since the Fire Industry (particularly England’s Fire Establishment, AHJ’s, etc) dislikes, with intensity, the whole idea of ‘environmental impact’ … the concept of ‘sustainable development’ is hardly understood … and no consideration is given to the reasonable fire safety and accessibility needs of ‘vulnerable building users’ (including people with activity limitations, refugees, migrants, etc).
The tragic 2017 Grenfell Tower Fire, and its sad aftermath, have demonstrated how dysfunctional, and rotten to the core, is the whole national system of Building Fire Safety in England. More than 3 years later … on the evidence to date of an ongoing, incompetent Inquiry and a series of shoddy responses from Government … will survivors and the victims’ families ever receive Justice, and find Peace ? cf. The 1981 Stardust Discotheque Fire in Dublin. Survivors and victims’ families are still waiting for the truth to be revealed.
In parallel, mutual recognition of British Professional Building Designers, e.g. Architects, Structural Engineers, Fire Engineers, etc., within the European Union will cease.
In parallel, British Fire Research involvement in EU Research Networks will also cease … unless a heavy price is paid to be involved as a 3rd Country. British Institutions should forget any notions they might have about Network Leadership.
In parallel, Information and Data Flows between Britain and the EU will be disrupted or cease altogether … unless Britain complies fully with the requirements of EU General Data Protection Regulation (GDPR) 2016/679. As a vassal state of the USA, this compliance may prove difficult for Britain !
.
EU Fire Safety Related Product/System Manufacturers ~ A Word of Caution !
Many EU Construction Product/System Manufacturers continue to use the services provided by British Fire Test Laboratories and/or Fire Consultancy Organizations located in Great Britain … some of which have already established EU-based dummy companies and letterheads. These British organizations must be avoided altogether. For example, the practice of fire testing in England and later adding a title page of a Full Test Report with an EU location address is entirely unacceptable !
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.
.
.
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.
.
.
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.
.
.
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’.
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 …
.
[ 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. ]
.
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.
.
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.
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.
.
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.
.
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.
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.
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 …

Fire Safety for All – Nobody Left Behind !
The rising 21st Century Cities of the Asia-Pacific Region each encompass:
a) an interwoven, densely constructed core ;
b) a very large and widely diverse resident population ;
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. ]
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).
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.
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.
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’.]
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 !
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.
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.

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.
