4. Basic Fire Safety Strategy
The compartmentation in this building is excellent as required by the Building
Regulations in 2008.
The compartmentation is such that the ‘stay put’ principle which forms the basis for fire
safety in most flats could be adopted.
In these flats the ‘stay put’ principle is not the policy. All of the flats and common parts
are fitted with an interlinked fire detection and warning system which alerts occupants to
evacuate the building. The system automatically calls the Fire & Rescue Service
through a 24/7 alarm receiving service.
.
5. Fire Hazards
Combustible/Flammable Materials
Refuse & recycling materials in the bin store and outside containers.
Soft furnishings to the chairs/sofas in Reception and the Common Room.
Floor coverings in corridors, mail in the metal mail boxes at Reception, paper and files in
the Manager’s Office.
Soft furnishings and normal dwelling combustible materials in the Flats.

Fixed electrical installation for lighting and heating in the flats and common areas (all
heaters are electric powered and fixed to the walls).
Other portable and transportable electrical equipment in the common areas and flats.
6. Fire Risks Reduction Measures
The flats and common parts are ‘No Smoking’.
Access to the building is only by key fob or via the apartment intercoms, this reduces the
risk of malicious fires from unauthorised persons entering the building.
The Building Manager and Warden/Cleaner monitor the premises and the fire
prevention/protection measures on a daily basis.
A Security Officer is contracted to patrol the building and site from 2200hrs to 0400hrs
on Thursday, Friday and Saturday each week. Photographs of all the occupants are
displayed on the wall in the Office to assist the Security Officers.
15 CCTV cameras are positioned in and around the building to help deter criminal
behaviour and identify offenders.
All areas are kept tidy and well organised. The corridors and staircases are kept free of
items and materials which could cause fires or impede means of escape.
Refuse & recycling materials from the Flats are stored in a dedicated of Store with fire
resisting construction. The internal access is protected by double (FD30S) fire doors
and the store is secured from the outside. Smoke detection is provided in this Store to
give early warning of a fire situation.
The fixed electrical installation incorporates the requirements of the current BS
7671:2008 and IEE Wiring Regulations and is inspected and tested every 5 years by
electrical contractors. Transportable and portable equipment in the common areas and
flats are inspected and tested annually.
A lightening conductor system is installed around the building.
Monthly safety checks are carried out by Incentive FM Ltd. as part of the facilities
management contract.
7. Compartmentation

Priority
Medium
The doors should be to FD30 standard as specified on
the fire plan design drawing but intumescent seals
were not visible which are required on this standard of
door.
It should also be confirmed that fire resistant
(intumescent) air transfer grilles have been fitted
between the louvre grills (to give hot smoke protection)
Unwanted items should be cleared out of these units to
reduce fire risks.

Details
The central gap is too large in parts for the intumescent
seal to work properly (the gap is between 5mm &
10mm, it should be between 2mm & 4mm).

There are no cold smoke seals on this door which
should be fitted to maintain the FD30S standard
protection for the escape route.

Refuse
Recycling
Room
This room is a special fire risk and the design
requirements are a fire resisting lobby with 2 selfclosing, fire resisting doors to FD30S standard.
The inner door requires a self-closing mechanism,
intumescent and cold smoke seals. A large gap at the

The design intention was that all refuse and recycling
bins be kept in the fire resisting store. This has not
been kept up, all but the bin in use are now kept
outside which creates risks of maliciously started fires
in these bins affecting the building and occupants.

compound or by other means to prevent them being
moved by unauthorised persons.

assessment, it is considered that the likelihood of a fire occurring at this building is
Unlikely (2)
Taking into account the nature of the building, the occupants, the fire protection and
procedural arrangements observed at the time of the assessment, it is considered that
the consequences of a fire occurring would be Minor (2).
