‘A Gentle Whisper in Your Ear’

Building Fire Emergencies – What is a ‘Place of Safety’ ?

As I have travelled around … not just Ireland, but many other countries as well … it still remains a puzzle to me, today, why so many Fire Emergency Assembly Areas are located just outside the main entrance of a building.  These locations are not safe in a ‘real’ fire emergency … and they should not even be used for the purposes of test/drill evacuations !

Is the guidance contained in current Building & Fire Regulations, Codes and Standards on what is a ‘Place of Safety’ in a fire emergency clear, simple, direct and precise ?   Are you joking ?   No way !   Let us take a few examples close to home …

In Ireland:

When you look at the array of different Technical Guidance Documents (Building Regulations) at the same time … TGD B (Fire Safety) is way out of proportion, in size, compared to all of the others.  You would expect, therefore, to find exactly what you were looking for in that document.  Wouldn’t you ?

TGD B (2006), Paragraph #1.0.9 – Definitions

Place of Safety

A place, normally in the open air at ground level, in which persons are in no danger from fire.

Clear as mud !   If there is a fire on O’Connell Street in Dublin … a person is safe on Patrick Street in Cork !   But, how is any Building or Facilities Manager expected to work with such a vague definition ?

 

In England & Wales:

No practical definition, as such, is readily provided.  The nearest thing to a definition is an amalgam of the following …

Building Regulations, Requirement B1 – Means of Warning & Escape

The building shall be designed and constructed so that there are appropriate provisions for the early warning of fire, and appropriate means of escape in case of fire from the building to a place of safety outside the building capable of being safely and effectively used at all material times.

Approved Document B: Volume 1 – Dwellinghouses & Volume 2 – Buildings Other Than Dwellinghouses

The ultimate place of safety is the open air clear of the effects of the fire.

British Standard BS 9999 : Code of Practice for Fire Safety in the Design, Management & Use of Buildings : 2008

Place of Ultimate Safety

Place in which there is no immediate or future danger from fire or from the effects of a fire.

Again … all as clear as mud !   Again … how is any Building or Facilities Manager expected to work with such vague guidance ?   Have you also noticed the additional obfuscation introduced by use of the word ‘ultimate’ in BS 9999 ?

 

It is hard to escape the conclusion that what is urgently needed is a fundamental transformation and re-shaping of the tired, antiquated and flawed ad-hoc assembly of prescriptive ‘solutions’ contained in current national building and fire regulations, codes, standards and administrative provisions … whatever their origin !

 

Now … try this for clarity, simplicity, directness and precision …

Place of Safety (Fire Incident in a Building, No Explosion Hazard*)

Any location beyond a perimeter which is [100]* metres from the fire building or a distance of [10]* times the height of such building, whichever is the greater

and

where necessary and effective medical care and attention can be provided, or organized, within one hour of injury

and

where people can be identified.

* Where there is a Risk of Explosion … multiply the numbers in square brackets above by 4.

Was that good for you ?

 

Furthermore …

The Route to any Place of Safety must be Accessible for All Building Users, including people who use wheelchairs, the visually impaired, frail older people, women in the later stages of pregnancy, children, etc., etc.

 

 

With regard to an Adequate, never mind a Proper, Awareness of Disability-Related Issues at a Fire Scene … it is shocking to realize how almost non-existent this is among Fire Services … not just in Ireland and Britain … but in the rest of Europe and North America as well.

Even a hint of criticism will usually … not always … meet the Neanderthal Fire Service Response: “Have you ever been in a ‘real’ building fire ?”

My Response is: “Do you have to be a hen to know when an egg is bad ?”

This discussion will continue later … have no doubt … that is a promise !

Disability Access Certificates – Parts M & B ? (II)

In everyday practice, the usual short introductory text in Technical Guidance Document M (Ireland) which refers to a linkage between ‘access and use’ of a building with ‘fire safety’ has little impact, because it is not explained … and is typically ignored.

In general … the basic problem is that this issue is hardly dealt with … at all … by Local Fire Authorities right across the country in their handling of Fire Safety Certificates … and where it does become part of the process, it receives inadequate attention.  There are exceptions.

A major drawback with the current vertical approach to our Building Regulations … each of the Parts has its own separate Supporting Technical Guidance Document … is that people are not sufficiently aware of the important horizontal linkages between the different Parts.  For example, all of the other Parts must be linked to Part D.  Quick, run to find out what Part D covers !   Another two examples … Part B must also be linked to Part A and Part M … and Part M must also be linked to Part K and Part B.

So … while grudgingly having to accept that the scope of TGD M should have some limit, under the current flawed system … a precise intervention with just one or two sentences, at critical places in the guidance text, would help to improve the overall consideration of fire safety issues, relevant to Part M, by building designers … and client or construction organizations.

 

Here are a Few Suggestions for Discussion …

1.  Revise Paragraph #0.6 of Draft TGD M (2009) & Add a Title …

Fire Evacuation for All

” Accessibility encompasses the full range of activity related to buildings: to approach, enter, use, egress from under normal conditions, and evacuate a building independently during a fire emergency, in an equitable and dignified manner.  Provision for access and use must, therefore, be linked to provision for fire evacuation.  For guidance on design for evacuation, reference should be made to Technical Guidance Document B (Fire Safety).”

Note:  No such guidance is contained in TGD B (2006).  It would be a great wonder if any person with a disability could actually evacuate a building which had been designed in accordance with TGD B.  To take a simple example … all of the ‘stairways’ in Table 1.5 of TGD B – Minimum Width of Escape Stairways will not facilitate contraflow or the assisted evacuation of mobility and visually impaired people.  Furthermore, those minimum widths specified in the Table may have a clear width which is 200 mm less.  See Methods of Measurement, Paragraph #1.0.10 (c) (iii) … ” a stairway is the clear width between the walls or balustrades, (strings and handrails intruding not more than 30 mm and 100 mm respectively may be ignored) ” !   What an incoherent mess !!

2.  Insert New Sentence at the End of Paragraph #1.1.1 of Draft TGD M (2009) …

Objective (Approach to Buildings)

” Consideration should be given to the use of the approach and circulation routes around a building as accessible routes to a ‘place of safety’ during a fire emergency.”

3.  Insert New Sentence at the End of Paragraph #1.2.1 of Draft TGD M (2009) …

Objective (Access to Buildings)

” Consideration should be given to the use of all entrances to a building as accessible fire exits during a fire emergency.”

4.  Insert New Paragraph at the End of Paragraph #1.3.4.1 of Draft TGD M (2009) …

Passenger Lifts

” Manual handling of occupied wheelchairs in a fire evacuation staircase, even with adequate training for everyone directly and indirectly involved, is hazardous for the person in the wheelchair and those people – minimum three – giving assistance.  The weight of an average unoccupied powered wheelchair, alone, makes manual handling impractical.  Lifts in new buildings should, therefore, be capable of being used for evacuation in a fire situation.  For guidance on the use of lifts for fire evacuation, reference should be made to Technical Guidance Document B (Fire Safety).”

5.  Insert New Paragraph and New Sentence at the End of Paragraph #1.3.4.2 of Draft TGD M (2009) …

Internal Stairs

” To allow sufficient space to safely carry an occupied wheelchair down or up a fire evacuation staircase, and to accommodate contraflow, i.e. emergency access by firefighters entering a building and moving towards a fire, while people are still evacuating from the building to a ‘place of safety remote from the building, the clear unobstructed width (exclusive of handrails and any other projections, e.g. portable fire extinguishers, notice boards, etc.) of the flight of a single, or multi-channelled, stairs should not be less than 1 500 mm.  The surface width of a flight of stairs should not be less than 1 700 mm.”

Note:  See Footnote (5) to Table 1.5 in TGD B (2006) … ” The minimum widths given in the table may need to be increased in accordance with the guidance in TGD M: Access for People with Disabilities.”   DUH ?

And …

” For the purpose of safe assisted fire evacuation of people, the rise of a step should not have a height greater than 150 mm, and the going of a step should not have a depth less than 300 mm.”

6.  Insert New Sentence at the End of Paragraph #1.5.1 of Draft TGD M (2009) …

Objective (Facilities in Buildings)

” Consideration should be given to the use of relevant facilities within a building, by people with disabilities, for the purposes of fire safety, protection and evacuation.”

7.  Insert New Sentence at the End of Paragraph #1.6.1 of Draft TGD M (2009) …

Objective (Aids to Communication)

” Consideration should be given to the use of relevant aids to communication, by people with disabilities, for the purposes of fire safety, protection and evacuation.”

Note:  More guidance could be provided under each of the individual paragraphs of Section #1.6 of Draft TGD M (2009).  See Draft International Accessibility-for-All Standard ISO 21542.

8.  Insert New Section #2.6 of Draft TGD M (2009) …

Fire Safety in Dwellings for People with Disabilities

Fire Evacuation of People with Disabilities – Reality Bites ?

Re: Seán’s Comment, dated 2009-03-06.

 

Yes, the guidance provided in Technical Guidance Document B (Ireland) is inadequate … and the same can equally be said of Approved Document B (England & Wales).

 

And yes, you will find only partial answers in British Standard BS 9999, even though it was only published on 31st October 2008 last.

 

Access Consultants in Ireland and Great Britain rarely deal with any matters relating to fire safety in buildings.

 

 

 

Please allow me, therefore, to fill in some gaps for you.  The following guidance is suitable for application in any European country …

 

People with Activity Limitations (2001 WHO ICF) experience many difficulties when attempting to independently evacuate a fire building.  However, our reasoning is very simple.  If we can get things right for the most vulnerable building users, we get them right for everyone else also.

 

 

The Target Destination … whether evacuation is independent, assisted by other building users or accomplished by means of firefighter rescue … is a ‘Place of Safety’.  This term is not well defined in legislation or codes.

 

Building User ‘Place of Safety’:

Any location beyond a perimeter which is [100] metres from the fire building or a distance of [10] times the height of such building, whichever is the greater … and … where necessary and effective medical care and attention can be provided, or organized, within one hour of injury … and … where people can be identified.

 

Where there is a Risk of Explosion … multiply the numbers in square brackets above by 4 (at least !).

 

 

 

All Fire Evacuation Routes – inside and outside a building – should comply with Accessibility Design Criteria.  This is an entirely alien concept to many Fire Prevention Officers in Local Authorities, and Fire Consultants !

 

Panic Attacks, during evacuation in a ‘real’ fire incident, exist.

 

Standard Movement Times, during evacuation in a ‘real’ fire incident, do not exist.

 

 

 

People should be able to reach an ‘Area of Rescue Assistance’ inside a building with ease.  In practice, few people understand what the word ‘refuge’ means (as in … refuge point, refuge area, area of refuge, etc).  As a result, these spaces are regularly misused and/or abused in buildings.  And there is great difficulty translating a word into other languages which, in English, can have so many meanings.  In Italian fire safety legislation, for example, ‘refuge’ has been translated as ‘spazio calmo’.  How crazy is that ?

 

So … what is an ‘Area of Rescue Assistance’ ?

A building space directly adjoining, and visible from, a main vertical evacuation route – robustly and reliably protected from heat, smoke and flame during and after a fire – where people may temporarily wait with confidence for further information, instructions, and/or rescue assistance, without obstructing or interfering with the evacuation travel of other building users.

 

 

This is a notional Area of Rescue Assistance …

 

A Clear Evacuation Width of 1.5 metres on the Evacuation Staircase facilitates ‘contraflow’ in a fire emergency (shown on the lower flight of stairs), i.e. emergency access by firefighters entering a building and moving towards a fire, while building users are moving away from the fire and evacuating the building … as well as allowing sufficient space to safely carry an occupied wheelchair down the staircase (shown on the upper flight of stairs).

 

 

 

 

Evacuation Skills & Self-Protection from Fire in Buildings …

A ‘skill’ is the ability of a person – resulting from adequate training and regular practice – to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal.

 

Building users should be skilled for evacuation to a ‘place of safety’, and test/drill/non-emergency evacuations should be carried out sufficiently often to equip building users with that skill.  Consideration should be given to practicing evacuation once every month or, at most, every two months; once a year is inadequate.  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 a ‘real’ fire incident.

 

Since Fire Protection Measures and Human Management Systems are never 100% reliable … it is necessary for frail older people and building users with disabilities to be familiar with necessary guidelines for self-protection in the event of a fire emergency.

 

 

Assisted Evacuation & Rescue Techniques …

Firefighters have two functions:

-         fighting fires ;  and

-         rescuing people who are trapped in buildings, or for some reason, cannot independently evacuate a building which is on fire.

 

People with disabilities are participating more and more, and in ever increasing numbers, in mainstream society.  It is necessary, particularly for firefighters, to become skilled in how best to rescue a person with a disability from a building, using procedures and equipment which will not cause further harm or injury to that person.

 

Manual handling of occupied wheelchairs in a fire evacuation staircase, even with adequate training for everyone directly and indirectly involved, is hazardous for the person in the wheelchair and those people – minimum three – giving assistance.

 

Generally … Powered Wheelchairs are too heavy for manual handling in any situation.

 

For these reasons, all lifts/elevators in new buildings should be capable of being used for fire evacuation.  Lifts/elevators in existing buildings, when being replaced or undergoing major overhaul, should then be made capable of being used for fire evacuation.

 

Local Fire Authorities should ensure that they possess the necessary equipment to rescue people with a wide range of impairments, and that specialized rescue equipment is regularly serviced and maintained.  Every Fire Authority should have an ‘accessible’ and ‘reliable’ Emergency Call System which is available, at all times, to the public within its functional area.

 

It is essential that every Firefighter is fully aware of this important public safety issue, and is regularly trained in the necessary rescue procedures involving people with a wide range of impairments.
