  3. Occupant safety

  4. Evacuation You must not rely on the fire and rescue service • There is a duty of care towards building and/or service users • Their safety is the responsibility of the responsible person / duty holder • There must be a strategy for evacuating the building • The plans need rehearsing with all who may require assistance • The HM Guidance documents clearly state: “ The evacuation plan should not rely on fire and rescue service involvement for it to be effective”

  5. Stay put / defend in place • Principal evacuation strategy adopted in blocks of flats, sheltered and extra-care housing • This strategy is undoubtedly successful in an overwhelming number of blocks of flats, regardless of whether these are general needs blocks or specialisedhousing. • In 2014-2015, of over 7,000 accidental fires in purpose-built flats, only 32 fires necessitated evacuation of more than five people with the assistance of the fire and rescue service (HO Fire Stats)

  6. LACORS • ‘Blocks of flats which were constructed or converted in compliance with the Building Regulations 1991, approved document B or equivalent may adopt a different approach such as ‘stay-put’ as the level of compartmentation means there will be a low risk of fire spreading beyond its unit of origin.’

  7. Lakanal House • Built mid 1960’s • Refurbished in 2006/2007 • 14 storey • 98 maisonettes • Fire in July 2009 • 6 people died including 3 children

  8. Lakanal House • Dan Daly, London Fire Brigade assistant commissioner • “If buildings are built and maintained correctly, walls, floors and doors in flats and maisonettes give you protection from fire – a minimum of 30 to 60 minutes – so, if there is a fire elsewhere in the building but not inside your home you’re safer staying in your flat unless heat or smoke is affecting you. Stay put and call 999.”

  9. Lakanal House Neither the client nor contractors submitted a Building Control notice of any sort, or sought advice or consultation on Building Regulations. Building Regulations or fire protection of any kind barely featured in their discussions, except in relation to options on fire-rated kitchen doors. Failure to engage with building control meant there was no inspection of the works or building control presence on site that might have spotted the historical problems.

  10. Historical problems • A section of the flats’ internal timber staircase juts out into the corridor, and had been inadequately fire protected in the 1980s, leaving a direct route for fire to travel from flats to the corridor. A weakness in fire compartmentation dating from the installation of central heating in the 1980s – when the fireproof ceiling in the common parts was breached. Problems with the cross-ventilation strategy.

  11. What a difference a day makes Properties constructed or converted in compliance with the Building Regulations 1991 or later (and which still comply) will not require additional fire safety measures unless occupied in a manner other than intended under the original construction or conversion. Where a building did comply but has deteriorated through lack of maintenance, damage or other alteration then it may require additional measures.

  12. Grenfell Firefighters and residents have described the extent of smoke logging in the stairwell. Subsequent investigations focused on the flat front doors undertaken by consultants to the Metropolitan Police have identified that although rated to 30 minute fire resistant standard, they provided only 15 minutes fire resistance when tested.

  13. Stay put • Compartmentation in supported housing is not normally adequate to support a ‘stay put’ strategy, so it is normally necessary to evacuate all residents when fire occurs (unless in a purpose built block of flats). • Stay put approach may be essential to ensure that existing escape routes can be used effectively to prevent overcrowding on staircases, especially where the building has only one!

  14. Do fire doors work?

  15. Tenant modifications

  16. Overcladding • Dudhope Court – Dundee • Example of enclosure of balconies • From reclad residential tower block in London

  19. What does a fire risk assessment look like?

  20. Assessment Types • LGG Guide Fire safety in purpose built blocks of flats • Type 1 – Common parts only (non-destructive) • Type 2 – Common parts only (destructive) • Type 3 – Common parts and flats (non-destructive) • Type 4 – Common parts and flats (destructive)

  21. People and Fire • Some misconceptions must be addressed, for example: - • Do people just leave the premises when they suspect a fire or when a fire alarm sounds? • Why would they suspect a fire had started? • If they did what would they do? • What do they think if a fire alarm goes off?

  22. Evacuation Planning • Human Behaviour • Evacuation time • Recognition time • Response time • Dealing with the fire • Building characteristics • Occupant characteristics • Evacuation protocols and procedures “ The evacuation plan should not rely on fire and rescue service involvement for it to be effective”

  23. Detection and alarm • Several significant considerations • BS5839-6 – in flats • BS5839-1 – in communal areas • Mixed systems • Minimisation of false alarms • Single stair buildings, limited capacity • Frequency leads to complacency • High integrity detection • Test and maintenance

  24. Suppression

  25. Avoid surprises!!
