Sorry Excuse For A Fire Evacuation Staircase In The Grenfell Tower – Supported By Shoddy ‘Expert’ Evidence !

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 :

  1. 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.

  1. 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.

  1. 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 …

Click to enlarge.

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 !

Click to enlarge.

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 !

Click to enlarge.

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 !!

Sustainable Fire Engineering Design & Process – Using No Way, As Way

2023-10-11:  Theory is one thing, but the practical working out and implementation of Sustainable Fire Engineering Design is something else …

The (Sustainable) Fire Engineer will already be an active, contributing member of a collaborative Project Design Team.  So, very early on in the Design Process for a Simple Building / Complex Building / Innovative Building / High-Rise Building / Tall Building or Group of Buildings (whatever) … he or she has a relatively mature sketch design on which to work, and major elements of the design can still be modified, without cost implications, based on her or his Creative Solutions which positively support and aid – not hinder, weaken or dilute – the Project Team’s Design Intent.

The Sustainable Fire Engineer should always / must, therefore, have a minimum competence with regard to Building Design and Construction in order to effectively communicate and creatively collaborate in these Design Teams.

[ Recommendation:  Instead of looking down on, or discriminating against, Architects … they should be warmly welcomed into the International Community of Fire Engineering … where their particular expertise is badly needed.]

A blank sheet of paper, pencil in hand … or, if you prefer, an empty monitor screen, with mouse poised to move … and how to proceed … should it be this fire safety strategy (?) … or a different, more appropriate fire safety strategy (?)

.

Sustainable Fire Engineering Design Objectives …

[ Reality – Reliability – Redundancy – Resilience ]

Achieve a Reliable Level of ‘Fire Safety for All’ ;

Facilitate Resilience: Protect Property & Assure Firefighter Safety ;

Minimize Environmental Impact & Mitigate Climate Disruption ;

Adapt to Climate Disruption ;

Nurture Sustainability ;

Incorporate Ease & Reasonable Cost of Post-Fire Reconstruction.

At this early stage in the Design Process … treat Conventional Fire Codes as an irrelevancy in the context of the above Design Objectives … question the adequacy of out-dated, simple prescriptive solutions … and forget about European and North American biases with regard to Passive and Active Fire Protection Measures.  Investigate new Sustainable Building Materials & Smart Technologies.  Incorporate Factors of Safety throughout the Fire Engineering Design Process.  Always remember Defence in Depth and Redundancy.  Prioritize Construction Reliability.

.

Sustainable Design: Green Walls & Fire ?

‘Green Walls’ (also known as Planted Facades, Living Walls, Vertical Gardens, and Vertical Landscapes) is a general term which covers the architectural use of natural vegetation as a vertical element in buildings, both externally and/or internally ; intrinsically, each ‘Wall’ is different.  To be absolutely clear from a fire engineering viewpoint, there is no such thing as a ‘standard’ green wall which can be fire tested in a laboratory.  There are many benefits and advantages to these Walls … but, in future, they will play an important role in dealing with Climate Disruption, particularly the Urban Heat Island Effect in cities and large towns.

If properly installed and maintained … properly nourished and watered depending on local environmental conditions … Green Walls will not pose a fire hazard.  But those are a lot of ‘ifs’ !

Remembering Defence in Depth … the installed ‘sub-soil’ watering system for a Green Wall may be interrupted or break down, so a Smart Water Mist System will help with hydration of the vegetation, and cooling for building occupants/users, as Climate Disruption intensifies.  Some of the trees, shrubs or plants may wither and die, so a Water Sprinkler/Deluge (as appropriate) Fire Suppression System will deal with any accidental or intentional outbreaks of fire.

Sustainable Buildings – An Immediate & Unprecedented Challenge Demanding Genuine Collaboration !

2023-09-26:  At the time of writing, the 78th Session of the United Nations General Assembly is taking place in New York City.  Midway through the U.N. Sustainable Development Framework Agenda 2015-2030News about its failing progress is very discouraging

>  Amid growing geo-political crises and war, Multi-Lateralism has little chance to operate successfully and there is a growing stalemate within the Security Council ;

>  Extreme Weather Events (e.g. heatwaves, droughts, severe storms and rainfall, flooding) are becoming a regular occurrence across the Globe, and their impacts are already devastating ;

>  Only 15% of the Sustainable Development Goals are barely on track, while development gains in other SDG’s have reversed ;

>  Not only are Climate Disruption Targets not being met, but global greenhouse gas emissions are actually increasing.

Earlier this month (September 2023), the #UN published a Report: United in Science 2023 – Sustainable Development Editionhttps://library.wmo.int/idurl/4/68235

Compiled by the World Meteorological Organization (#WMO) under the direction of the U.N. Secretary-General, it brings together the latest updates from key U.N. Partner Organizations with a focus on weather-, climate-, and water-related sciences, research and services in support of realizing Sustainable Human & Social Development:

Climate Disruption …

  1. Total Carbon Dioxide (CO2) Emissions from fossil fuels and land use change remained high in 2022 and the first half of 2023.  Fossil fuel CO2 emissions increased 1% globally in 2022 compared to 2021, and global average concentrations continued rising through 2022 and the first half of 2023.
  2. The years from 2015 to 2022 were the eight warmest on record, and the chance of at least one year exceeding the warmest year on record in the next five years is 98%.
  3. It is estimated that current mitigation policies will lead to global warming of around 2.8 °C over the course of this century compared to pre-industrial levels.  Immediate and unprecedented reductions in Greenhouse Gas Emissions are needed to achieve the goals of the 2015 Paris Agreement, i.e. 1.5 °C.

.

.

Sustainable Cities & Communities …

  1. Cities are responsible for a high proportion of global GHG Emissions and are highly vulnerable to the impacts of climate disruption and extreme weather events, which threaten the achievement of Sustainable Development Goal 11.
  2. Integrated urban weather, climate, water and environmental services, grounded in best-available science and research, are helping Cities to achieve SDG 11.
  3. Observations, high-resolution forecasting models and multi-hazard early warning systems are the fundamental basis for integrated urban services.

Good Human Health & Social Wellbeing …

  1. Trans-Disciplinary Research is fundamental to analysing, monitoring and addressing climate-sensitive health risks and climate impacts on the health sector.
  2. Climate disruption and extreme events are projected to significantly increase ill-health and premature deaths, as well as population exposure to heatwaves and heat-related morbidity and mortality.
  3. Scaling up investments in climate-resilient and low-carbon health systems, and progress towards universal health coverage (#UHC) are critical for the achievement of Sustainable Development Goal 3.

Deep & Genuine Construction Sector Collaboration …

[ Institutional Transformation ]

It is inevitable, therefore, that enormous pressures – social, economic, political, legal, and institutional – are being brought to bear on Building Design Professions, Engineers (all disciplines) and Construction Organizations to rapidly, reliably and creatively transform our existing Built Environment ; new buildings, which constitute just a small part of that workload, will be required to carry the heaviest burden.  To properly realize a Safe, Resilient and Sustainable Built Environment for ALL, however, Genuine Collaboration must be fostered … between each actor in the construction sector … between practitioners and scientists/researchers … and between different industrial sectors … silos broken apart and traditional barriers transcended.

.

Sustainable Buildings – Reality vs. Superficial Impressions …

The minimum Life Cycle for a Sustainable Building is 100 years.

To be capable of later #Adaptation, a Sustainable Building must possess a sufficient/appropriate, level of #Redundancy.  Lean construction ignores this issue.

Far too many people appear to be still ‘wrestling’ with an obsolete understanding of #Sustainability.  It has many more than just 3 Aspects (social, environmental, economic).  Time for everyone to cop on and catch up !

[ Legal Aspects of Sustainable Human & Social Development: If the World is Serious about Sustainability, it must Embark on a New Era of Global Lawhttps://www.weforum.org/agenda/2021/11/global-governance-sustainability ]

.

The International Fire Engineering Community, in particular, has a fixation with low-hanging fruit … ‘PV Panels’, ‘Timber Buildings’ … and ‘Performance-Based Fire Codes’, which are a hybrid of prescription (rather than Functional Fire Codes, which offer a more free, more open, and flexible option for designers).

So … before moving on in my next Post to look at the potential for Green Walls being a fire hazard, and comparing a top-down Sustainable Fire Engineering Design Approach with a bottom-up Conventional Fire Safety Approach … here is an interesting graphic image, developed by an architectural colleague in Berlin, Ar.Stefanie Blank, showing the difference between all-too-common superficial impressions and the reality of Sustainable Buildings …

.

As I have written many times before, the concept of Sustainable Human & Social Development is intricate, open, and dynamic … and it is also continuously evolving.  So too, the #SFE #RoadMap must continuously evolve.

Fully reflecting the content and views expressed above, it is necessary to further expand the Sustainable Fire Engineering Design Objectives on Page 10 of the Road Map … in order to clearly and directly integrate the issue of Climate Disruption

.

Urgent Need For Harmonized European Fire Statistics & The ‘FIRESTAT’ White Elephant !

2023-08-21:  In an earlier Post here, dated 2022-12-19, I presented a Road Map for Sustainable Fire Engineering (#SFE) … which finished on an Urgent Call to Action targeting three specific, fundamental aspects of a Creative Fire Engineering which is capable of answering the challenges of our Complex Built Environment in the 21st Century … under severe threats from Global Climate Disruption, Climate Synergies leading to near-term Climate Tipping Points … and a startling lack of Global Resilience, refer to the CoVID-19 Pandemic, and Supply Chain Chaos initiated by an old-fashioned Cold War I Warrior in Washington’s White House.

      2. Ethical Practice of Fire Research and Science
      3. Reliability of Fire Statistics …

.

From Any Point Of View … the Final Report of ‘EU FIRESTAT’, a project financed by the European Parliament and commissioned by European Commission Directorate-General DG GROW, is a white elephant … a plodding hippopotamus … a retrograde step … a bitter disappointment !!!  Completed in July 2022, it comes nowhere near outlining a viable system for the development of urgently needed Harmonized European Fire Statistics … which must be managed and co-ordinated by #Eurostat, in Luxembourg.

The #FIRESTAT Objectives were extremely limited …

‘ The review proceeds from the assumption that fire incident data can serve a number of important purposes – helping to reduce fires and losses, identifying opportunities for safety interventions and education programs, guiding the allocation of public resources to areas of greatest need and impact, and monitoring progress of safety initiatives.’

Nowhere, in this Report, is there any reference to Sustainable Human and Social Development.  Where there are references to ‘sustainability’, these are specifically concerning the long-term financial resourcing of statistical systems.

And nowhere is there even the faintest understanding that Fire Engineering has an essential and critical role in the realization of a Safe, Resilient & Sustainable Built Environment For ALLFire Engineering Performance Indicators, Targets and Benchmarks must be developed to facilitate that realization ; and Reliable Fire Statistics are their starting point and basic ingredient.

[ The European Standards Organization (#CEN) has a Webpage dedicated to its part in reaching the Sustainable Development Goals (#SDG’s) at … https://www.cencenelec.eu/european-standardization/sustainable-development-goals-sdgs/ ]

The Report’s Executive Summary (in English, French, and German) covers the limited range of the Project pretty well … and it is almost easy to read.  The ‘great and the good’ of Conventional Fire Engineering, both organizations and individuals, were involved in this Project …

.

The Final Report’s Boxed Recommendation 3, on Page 8, lists 8 Variables / Statistics to be collected as a Tier 1 / 1st Priority across Europe, from Ireland all the way down to Türkiye :

  •  Number of Fatalities ;
  •  Number of Injuries ;
  •  Age of Fatalities ;
  •  Primary Causal Factor ;
  •  Type of Building ;
  •  Incident Location ;
  •  Incident Date ;
  •  Incident Time.

So, for instance … the only Fire Statistic related to the Human Condition of Fatalities and Injured which would have been gathered after the 2017 Grenfell Tower Fire in #London was … Age of Fatalities … which, in the context of what actually happened on that tragic night and knowing the very large numbers of People with Activity Limitations (2001 WHO ICF) and other Vulnerable Building Users who died, or were injured, in the fire … is a very serious error, and entirely ridiculous !!??!!   FUBAR !!

Essential Variable / Statistic Correction: Age, Gender and Vulnerability of Victims (whether Fatality or Injured).  This is critical information and, whatever the resource implications, must be collected.

And if that wasn’t bad enough … this cack-handed approach to the development of Harmonized European Fire Statistics opens up the probability of another Morán with a computer, after a similar fire incident, again showing that a similar High-Rise Residential Tower could be evacuated down a single, narrow, badly designed staircase in 7 minutes.  Say no more !!!

.

J’Accuse / I Accuse the International Fire Engineering Community of being intentionally and maliciously Deaf, Dumb and Blind to the desperate Fire Safety Needs of People with Activity Limitations, including People with Disabilities, and other Vulnerable Building Users !

.

Concerning Incident Date … the Consortium appears to be completely unaware that the European Standard Short Format Date is … Year-Month-Day (YYYY-MM-DD) !!   See 4.2.2. in the Final Report.  Sloppy, Sloppy, Sloppy.

Generally concerning Tier 1 Statistics … where is there any serious consideration of the deep and substantial Green / Environmental / Climate Disruption Mitigation and Adaptation Measures being imposed on the Design and Operation of New and Existing Buildings … which are already causing serious fire safety problems ???   See many previous Posts on this Technical Blog.

.

Colour Image showing #IPCC AR6 Synthesis Report Figure 5a: ‘Limiting warming to 1.5 C and 2 C involves rapid, deep and in most cases immediate greenhouse gas emission reductions’ … from the Intergovernmental Panel on Climate Change 6th Assessment Report.  Current emission reduction policies will result in global warming of approximately 3.2 C, which is far off target.  Click to enlarge.

.

The Final Report’s Boxed Recommendation 3, on Pages 8 & 9, goes on to list 6 Extra Variables / Statistics to be collected as a Tier 2 / 2nd Priority across Europe, from Portugal all the way up to Finland :

  •  Number of Floors ;
  •  Area of Origin ;
  •  Heat Source ;
  •  Item First Ignited ;
  •  Articles Contributing to Fire Development ;
  •  Fire Safety Measures Present.

Concerning Fire Safety Measures Present … my patience is at an end !  I am heartily sick and tired of pointing out that there is no such thing as a ‘Fire Door’ ; it does not exist !!   It is ALWAYS a Fire Resisting Doorset !!!   See 4.4.3.

.

This EU ‘FIRESTAT’ Report properly belongs to the Twilight Zone of the last Century … and in today’s Recycling Bin !

.

And Even More Worrying …

.

Concerted Resistance to answering the Fire Safety Needs of Vulnerable Building Users ;

The mistaken view that ‘Sustainability’ is merely a graft-on / optional extra to Conventional Fire Engineering ;

Constraining Building Fire Safety Performance within the boundaries of Current Fire Codes ;

.

Is the EU ‘FIRESTAT’ Final Report another disturbing sign of the growing Trend towards #GREENWASHING in International Fire Engineering ?

Sustainable Fire Engineering – Road Map To A Safe, Resilient & Sustainable Built Environment For ALL

2022-12-19:  Following on, directly, from the 2016 Dublin Code of Ethics

[ A personal Code of Ethics – is / must be – the basis for Effective Sustainability Implementation ]

.

Multi-Disciplinary Input  > Trans-Disciplinary Output

Sustainable Fire Engineering (SFE) is a Facilitator – no more than Architecture, Structural Engineering, or Spatial Planning – in the task of realizing a Safe, Resilient and Sustainable Built Environment for All.  However, SFE has an essential role to fill throughout the difficult journey towards that target.  In close collaboration with other design disciplines, many iterations … twists and turns along the road … will be necessary.

Beware Greenwashing !

Sustainability is NOT a graft-on, or an optional extra, to Conventional Fire Engineering.  This intricate, open, dynamic and continuously evolving Concept must cut right to the core of everyday design practice, and must positively impact all areas of that practice.

Ethical Transformation

In this third decade of the 21st Century … the Safety Objectives in current Fire Codes / Regulations are limited, inadequate, and lagging far behind today’s creative moulding and re-shaping of the Built Environment ;  they are almost, but not entirely, irrelevant in the context of the urgently required transformation of conventional fire engineering.  For anybody who cannot see the broad, beautiful landscape beyond codes and regulations … this SFE Road Map is definitely not for you.  For those who can see, your constant companion … your compass … will be a Personal Code of Ethics.

.

Essential Considerations Before Starting Out On The Road …

1.  World Trade Centre Attacks in New York City, on 11 September 2001.  Two sets of important Recommendations were issued by the U.S. National Institute of Standards and Technology (NIST) in 2005 and 2008.  Not only is the implementation of these still incomplete, but the solid progress which has been made e.g. on Firefighter Safety, is continuously under threat from vested interests.  Other jurisdictions have tended to ignore the Recommendations.  SFE takes full account of this Extreme Man-Made Event.

2.  Grenfell Tower Fire in London, on 14 June 2017.  Evidence at the Official Inquiry continues to shock and horrify ;  the entire fire safety regulatory edifice in England is dysfunctional, and it poses a real and serious danger to Public Health and Safety.  Inquiry Phase 1 Recommendations were issued in 2019.  Already, the Recommendation concerning Evacuation for Vulnerable Building Users & PEEP’s (#33.22 e and f) has been discarded by AHJ’s … and it has also been stated (#34.14) that as everything about the single narrow staircase in the Tower appeared to be OK, it will not be investigated in Inquiry Phase 2 … a sure sign of dysfunctional dysfunction !  SFE sees beyond these major flaws.

3.  Sustainable Buildings   Il Bosco Verticale Towers in Milano … this exciting Project, designed by Stefano Boeri and completed in October 2014, has become the International Icon for innovative / environment-friendly construction.  These new approaches to building design are posing enormous fire safety challenges.   [ Remember back … was it 15 years before fire codes were able to ‘solve’ the Atrium in buildings ? ]   SFE, however, must cope with this extraordinary level of architectural creativity ;  and Fire Engineering Practitioners must be capable of active participation, collaboratively, within Project Design/Construction Teams.

Looking past the Milan Project … it is important for the reader to experience a more rounded flavour of where the exciting synergy between Creative Design and the Inclusive Language of Sustainability is at present, and where it is tending to go …

4.  Building Energy Performance Rating Schemes   Under enormous environmental and political pressures, the headlong rush to conserve energy in buildings, and to make them more energy efficient … especially after the 2022 Russian Invasion of Ukraine … is proceeding in blissful ignorance of fire safety and necessary independent technical controls.  Measurement of real building performance, after energy refurbishment has been completed, is generally avoided.

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’.

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.

.

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.

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.

..

2019-12-21:  Recapping with regard to Vulnerable Building Users … the Grenfell Inquiry Phase 1 Recommendations are pathetically and disgracefully inadequate !  At a later stage and in order to make amends for this serious error … Inquiry Chairperson, Sir Martin Moore-Bick must direct that Proper Consideration – not just Token Consideration – be given, in Law, to the Fire Safety of Vulnerable Building Users, who include people with activity limitations, children under 5 years of age, frail older people (not ALL older people !), women in late stage pregnancy, people with disabilities, refugees, migrants, the poor, and people who do not understand the local culture or cannot speak the local language … OR, to put it another way and to remove any ambiguity … any person who may be vulnerable in a fire emergency, i.e. those with limited abilities in relation to self-protection, independent evacuation to an external place of safety remote from the building, and active participation in the building’s fire emergency procedures.

Do you care that Vulnerable People also use Your Building ?

Now, Over 2.5 Years After The Grenfell Tower Fire … London Fire Brigade Commissioner (#LFB), Dany Cotton, has recently stated that she will retire at the end of December 2019.

On 17 December 2019 … The National Inspectorate in Britain for Police and Fire Services (#HMICFRS … www.justiceinspectorates.gov.uk/hmicfrs) published a report into the performance of London Fire Brigade.  Some extracts from that document …

‘ We have concluded there is a long way to go before London Fire Brigade is as efficient as it could be.  We have criticised both the way it uses resources and makes its services affordable now and in future.  In some areas it is wasteful.  While it has made savings, these are not of the level made in other services.

Worryingly, the Brigade is inadequate at getting the right people with the right skills.  It also needs to improve how it promotes the right values and culture, ensuring fairness and promoting diversity as well as managing performance and developing leaders.

The tragic fire at Grenfell Tower in 2017 was one of the biggest challenges London Fire Brigade has ever had to face.  The incident has had a profound effect on how the Brigade now performs.  Although our findings are broadly consistent with those of the Grenfell Tower Inquiry, it must be emphasised that this was an inspection of the Brigade in 2019.  We found that while the Brigade has learned lessons from Grenfell, it has been slow to implement the changes needed.  This is unfortunately typical of the Brigade’s approach to organisational change.’

Title Page of GB’s National Inspectorate (HMICFRS) Report, published on 17 December 2019.

HMICFRS Report on the Performance of London Fire Brigade  (PDF File, 768 Kb)

If Dany Cotton is the only person to go at the end of December 2019, this is very obviously political scapegoating !

Very Quickly … the entire Culture and Value System of London Fire Brigade must change for the better.  And to ensure that this transformation is Immediate and Fully Effective … ALL of Dany Cotton’s Senior Commanders must also go, or be fired … including Dany’s intended replacement, Andy Roe !

In addition … because it is still attempting to defend the criminal ‘Stay Put’ Policy … the National Fire Chiefs Council (#NFCC … www.nationalfirechiefs.org.uk/) in Britain must be held accountable.  Its Chair, Vice Chairs and those Lead Officers with responsibility for fire safety in buildings must ALL be replaced NOW !

.

FIRE  EMERGENCY  MANAGEMENT  PLANNING

The Grenfell Fire Inquiry’s Phase 1 Recommendations were published on 30 October 2019.  Under the initial topics covered … they are far from being comprehensive … they are fragmentary, lack depth and any sort of coherence …

[ Paragraph #33.10 ]  I therefore recommend:

a. that the owner and manager of every high-rise residential building be required by law to provide their local fire and rescue service with information about the design of its external walls together with details of the materials of which they are constructed and to inform the fire and rescue service of any material changes made to them ;

[ Paragraph #33.12 ]  I therefore recommend that the owner and manager of every high-rise residential building be required by law:

a. to provide their local fire and rescue services with up-to-date plans in both paper and electronic form of every floor of the building identifying the location of key fire safety systems ;

b. to ensure that the building contains a premises information box, the contents of which must include a copy of the up-to-date floor plans and information about the nature of any lift intended for use by the fire and rescue services.

I also recommend, insofar as it is not already the case, that all fire and rescue services be equipped to receive and store electronic plans and to make them available to incident commanders and control room managers.

[ Paragraph #33.13 ]  I therefore recommend:

a. that the owner and manager of every high-rise residential building be required by law to carry out regular inspections of any lifts that are designed to be used by firefighters in an emergency and to report the results of such inspections to their local fire and rescue service at monthly intervals ;

b. that the owner and manager of every high-rise residential building be required by law to carry out regular tests of the mechanism which allows firefighters to take control of the lifts and to inform their local fire and rescue service at monthly intervals that they have done so.

[ Paragraph #33.22 ]  I therefore recommend:

a. that the government develop national guidelines for carrying out partial or total evacuations of high-rise residential buildings, such guidelines to include the means of protecting fire exit routes and procedures for evacuating persons who are unable to use the stairs in an emergency, or who may require assistance (such as disabled people, older people and young children) ;

b. that fire and rescue services develop policies for partial and total evacuation of high-rise residential buildings and training to support them ;

c. that the owner and manager of every high-rise residential building be required by law to draw up and keep under regular review evacuation plans, copies of which are to be provided in electronic and paper form to their local fire and rescue service and placed in an information box on the premises ;

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 ;

e. that the owner and manager of every high-rise residential building be required by law to prepare personal emergency evacuation plans (PEEP’s) for all residents whose ability to self-evacuate may be compromised (such as persons with reduced mobility or cognition) ;

f. that the owner and manager of every high-rise residential building be required by law to include up-to-date information about persons with reduced mobility and their associated PEEP’s in the premises information box ;

g. that all fire and rescue services be equipped with smoke hoods to assist in the evacuation of occupants through smoke-filled exit routes.

.

Residents in High-Rise Buildings, whether public or private, must no longer wait in vain for a saviour, or to be saved by the ‘system’.  Instead, the time has arrived to become proactive, and to immediately initiate their own comprehensive programmes of Self-Protection In Case Of Fire … which go far beyond the Recommendations in Moore-Bick’s Phase 1 Report.

.

Fire Emergency Management Planning begins very early in the long life cycle of a building.  The following framework should be scaled up or down, depending on the size and extent of a project …

Fire Defence Plan (FDP)

A Fire Defence Plan (#FDP) elaborates the particular fire engineering strategy which has been developed for a specific building at design stage.  It is usually in electronic format and/or hard copy … and comprises fire engineering drawings, descriptive text (including a clear statement of the project’s fire engineering design objectives), a full construction specification (including façade cladding systems), fire safety related product/system information, with supporting calculations and the fire test/approval data which demonstrates their ‘fitness for intended use’.

A Fire Defence Plan must demonstrate a proper consideration for the fire safety, protection and evacuation of all building occupants/users, with a particular and integrated focus on vulnerable building users, especially people with activity limitations.  Refer to Personal Emergency Evacuation Plans (PEEP’s) in my previous post.

In ‘real’ everyday practice, as opposed to academic theorizing … effective fire compartmentation is very difficult to achieve.  Passive/active fire protection measures are never 100% reliable … sometimes nowhere near 100%.  Building management systems are very far from being reliable.  For these reasons, ‘Stay Put’ Policies must be completely avoided !

[ In the specific case of Health Care Facilities, e.g. hospitals, it is highly hazardous to patients and unacceptable with regard to their welfare that they be evacuated during a fire emergency to a place of safety which is remote from the building.  Instead, the optimal fire engineering strategy here is to ‘protect in place’ … which requires a very high level of independently monitored competence, quality and reliability in design, construction, management, operation, and servicing. ]

Fire Defence Plans become ‘live’ during Construction.

A hard copy of the Fire Defence Plan for a building must always be available for inspection on-site.  A copy of the fire defence plan must also be retained at a remote, safe and secure location off-site.

Fire Emergency Planning Committee (FEPC)

Immediately after the completion of construction and occupation of a building, a Fire Emergency Planning Committee (#FEPC) must be established by the building owner(s), in consultation with building occupants/users.  Membership of the FEPC must comprise representatives of the building owner(s), building occupants, and regular users of the building.  The Committee’s task must be to develop, implement and maintain a Fire Emergency Management Plan, consisting of the emergency response procedures and related training and regular practices, which are essential for the effective and efficient management of any fire emergency in the building.  Sufficient resources must be allocated to the FEPC, by the building owner(s), to ensure that it can satisfactorily complete this task.

The FEPC must ensure that all relevant legislative requirements are met and must examine, if necessary, the need for the appointment of competent, specialist advisors and support.  Special attention must be paid by the FEPC to the fire safety of vulnerable building occupants/users.  The FEPC must establish a Fire Emergency Control Room (#FECR), which must be fitted-out and competently operated – 24/7/365 – in accordance with the Fire Emergency Management Plan.  The FEPC must also appoint a competent Fire Emergency Control Unit Manager.

Fire Emergency Management Plan (FEMP)

The Fire Defence Plan is the basis for, and main component of, a building’s Fire Emergency Management Plan (#FEMP).  This document elaborates the fire emergency response procedures for an occupied building and is produced by the Fire Emergency Control Unit Manager, in liaison with the Local Fire Service.  It contains relevant information about the fire safety preparedness and prevention/protection/recovery measures in the building, and includes the pre-emergency, emergency and post-emergency roles, duties and responsibilities assigned to individuals and, in the case of their absence, nominated deputies.

The objective of a Fire Emergency Management Plan is to ensure that, in the event of a fire emergency, the health and safety of every building occupant/user is protected, including visitors to the building, contractors, and product/service suppliers … and access for, and the safety of, firefighters is assured.  Particular attention must be paid to those occupants with activity limitations.  All Personal Emergency Evacuation Plans (#PEEP’s) must be fully integrated into the overall Fire Emergency Management Plan for the building.  Documented procedures must accurately reflect reality, and real behaviour, in the building.

The Fire Emergency Management Plan must include the procedures, chosen methods of warning to be used during a fire emergency, management control and co-ordination during the fire emergency, communications between each member of the Fire Emergency Control Unit and the building’s occupants/users and with the Fire Service Incident Commander at the scene, emergency response equipment in the building, evacuation actions, arrangements for occupants/users with activity limitations, first-aid personnel, evacuation by lift/elevator fire evacuation assemblies, escalators, travellators and staircases, use and fitting-out of areas of rescue assistance (including visual monitoring and the provision of smoke hoods), lift/elevator lobbies (including visual monitoring and provision of smoke hoods) and floors of temporary refuge, up-to-date emergency contact details, etc.

The Fire Emergency Management Plan must always be available for inspection, in hard copy format, at a convenient location in the building.  A copy must be provided to all building occupants, as they request, in hard copy, electronic and/or alternative formats.  A further copy of the Fire Emergency Management Plan must be provided to the Local Fire Service, as they request, in hard copy and/or electronic formats.

To ensure its effectiveness, the Fire Emergency Management Plan must be regularly practiced at least every three months, tested and reviewed.  If necessary, e.g. in the case of large/complex building types or existing buildings having suspect levels of fire safety, the establishment of an on-site, permanent, competent/specialist Fire Emergency First Response Team (#FEFRT) must be considered.

Fire Emergency Control Unit (FECU)

The Fire Emergency Control Unit (#FECU) must be established by the Fire Emergency Planning Committee to implement, manage, and recommend improvements to the Fire Emergency Management Plan.

In the event of a Fire Emergency, instructions given by the Fire Emergency Control Unit Manager, or his/her Deputy, must take precedence over normal management structures and procedures in the building; and it shall be his/her duty to inform the Local Fire Service, immediately upon their arrival at the scene, about the number/locations of people still in the building, and the number/locations of vulnerable people who may need to be rescued.

Other members of the Fire Emergency Control Unit must accompany occupants/users as they evacuate to place(s) of safety, remote from the building.  Once there, a head count must immediately be taken by those members – now the Person in Charge at a place of safety – to establish the following:

  • That everybody is present, and that nobody has been left behind ;
  • That everybody is uninjured … or if anybody is injured, what appropriate Medical Aid is rendered and/or summoned.

Communications during a fire emergency between all of the interested parties involved can be fraught with difficulty … lack of discipline will cause misunderstandings and confusion … signal strengths may suffer interference because of the building’s construction.  If necessary, Repeater Units must be installed in the building at any signal ‘drop-zones’ … and the development of a Fire Emergency Management Communications ‘App’, for use on FECU/occupant/user smartphones, must also be considered.

The Fire Emergency Control Unit Manager must prepare for the swift and orderly transfer of the Fire Emergency Control Room and its personnel to a safe location off-site, in the unlikely event of a severe fire emergency in the building.

Fire Safety Training & Regular Practice Evacuations

The objective of fire safety training and regular practice evacuations, which are held at least every 3 months, is to ensure that everybody in the building is skilled for evacuation during a fire incident, using safe accessible routes to an external place/places of safety which is/are remote from the building.

Place(s) of Safety.  Click to enlarge.

Fire safety training and regular practice evacuations must be conducted by the Fire Emergency Control Unit Manager for all building occupants and regular visitors to the building, including FECU personnel.  Fire safety training material used, e.g. brochures, hand0outs and fact sheets, must be site-specific, appropriate to an individual’s role and responsibilities, and easily assimilated, i.e. can be comprehended by everyone, including people with activity limitations and those who are illiterate or may use different languages.

A programme of site-specific practice fire evacuations must be developed, in collaboration with the Local Fire Service, by the Fire Emergency Control Unit Manager.

Skill:  The ability of a person – resulting from proper training and sufficient regular practice – to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal.

Routine Fire Safety/Evacuation Inspections & Maintenance

The Fire Emergency Control Unit Manager must ensure that all fire safety and evacuation related aspects of the Fire Emergency Management Plan, including systems, products and fittings, are routinely inspected, tested and maintained/serviced.  Any deficiencies must be reported to the Fire Emergency Planning Committee at the completion of an inspection and/or test, and must be rectified as soon as it is reasonably practicable.  Records of all activities must be regularly updated and safely/securely stored in the building, with a duplicate copy provided to the Local Fire Service.

Fire Evacuation Performance Indicators (Metrics)

Performance indicators/metrics must be formulated by the Fire Emergency Control Unit Manager in order to evaluate the effectiveness of the fire emergency response procedures in the building.  During practice evacuations, the time between warning communications and first occupant/user movement, the time taken for evacuation to an external place/places of safety remote from the building, the evacuation routes chosen by occupants/users, and the time required to identify everyone who participated in the practice evacuation at the place/places of safety, including those occupants/users who did not participate, must all be recorded.

The Local Fire Service has two functions: a) to suppress and control a fire in the building, and to confirm extinguishment ;  and b) to rescue people in the building who are injured, trapped, or otherwise unable to independently evacuate, e.g. people waiting in areas of rescue assistance and lift/elevator lobbies.  In addition, therefore, the time taken for the first fire service vehicle to arrive on-site and, more importantly, the time taken for the fire services to arrive in sufficient strength to deal effectively with a fire emergency in the building must be recorded.  In the event that either or both of these times are inordinately long, an on-site specialist Fire Emergency First Response Team (FEFRT) must be established by the Fire Emergency Planning Committee.  The FEFRT must work under the control of, and report directly to, the Fire Emergency Control Unit Manager.

During the process of evaluation, generous allowance must be made for contraflow circulation during a real fire incident, i.e. emergency access by firefighters into a building and towards a fire, while building occupants/users are still moving away from the fire and evacuating the building.

The Fire Emergency Control Unit Manager must report, in full, the recorded performance and his/her evaluation of practice evacuations to the Fire Emergency Planning Committee.
