Portable Extinguishers - Siting
Whenever possible portable fire fighting equipment should be grouped to form a fire point. The fire point should be clearly indicated so that it can be readily identified.
In premises that are uniform in layout extinguishers should, whenever possible, be located at the same point on each floor.
If for any reason extinguishers are placed in positions hidden from direct view their position should be indicated by suitable signs, as described in BS 5499 : Parts 1 and 3.
Example of correct signage:
No person should have to travel more than 30 metres from the site of a fire to reach an extinguisher.
Type and Number of Portable Fire fighting Equipment
The basic provision of extinguishers within a building should be one extinguisher, of at least 13A rating, for every 200m2 of floor area, or part thereof, with at least two per floor.
However, for those buildings where an upper floor area is less than 100m2, one single 13A rated extinguisher may be acceptable on each floor.
Should the premises contain risks from flammable liquids, then B rated extinguishers should be provided.
Under normal circumstances a 34B rated extinguisher would equate to a 13A in this respect.
Location of Portable Fire fighting Equipment:
- Extinguishers should be sited in conspicuous positions where they are visible to anyone using an escape route.
- They should be mounted on brackets fixed to the wall or some other convenient structural feature.
- Ideally, larger extinguishers should be mounted so that they can be conveniently de-mounted for use without undue effort or risk of injury. In effect, this will mean mounting the extinguisher with the handle no more than 1m from the floor but, circumstances may dictate variations from this recommendation.
- Smaller and more easily handled extinguishers may be mounted with the handle about 1.5m from the floor level.
- Suitably constructed floor cradles may be acceptable in certain locations.
- Where there are special risks, extinguishers should be grouped conveniently in positions where any user will not be placed in danger whilst attempting to use them.
- Other suitable positions include near exits to rooms or storeys, corridors or lobbies, stairways and landings.
- Extinguishers should not be sited behind doors or inaccessible positions such as deep recesses or in cupboards.
- It is also necessary to consider their exposure to extremes of heat or cold as well as the risk of accidental damage during the normal day-to-day use of the premises. The operation of an extinguisher will be affected by temperature and this could even cause accidental discharge.
- In premises where theft and vandalism are a problem, extinguishers may be located in secure areas, but always under the supervision of trained staff.

Hose Reels and Fire Blankets
Where hose reels are provided, they should be located where they are conspicuous and always accessible, such as in corridors.
Fire blankets should be located in the vicinity of the fire hazard they are to be used on, but in a position that can be safely accessed in the event of a fire. They are classified as either light-duty or heavy-duty. Light-duty fire blankets are suitable for dealing with small fires in containers of cooking oils or fats and fires involving clothing. Heavy-duty fire blankets are for industrial use where there is a need for the blanket to resist penetration by molten materials.
If you are unsure about the number, type or, location of portable fire-fighting equipment or hose reels you need, you should check with the local fire authority before purchasing any such equipment.
Sprinkler Systems
In smaller workplaces, portable fire extinguishers will probably be sufficient to tackle small fires. However, in more complex buildings, or where it is necessary to protect the means of escape and/or the property or contents of the building, it may be necessary to consider a sprinkler system.
Sprinkler systems are traditionally acknowledged as an efficient means of protecting buildings against extensive damage from fire. They are also now acknowledged as an effective means of reducing the risk to life from fire. Systems are being developed which may be suitable for use in workplaces with residential areas, such as care homes and houses in multiple occupancy.
Sprinkler systems need to be specifically designed and installed to the appropriate hazard category in accordance with an approved code of practice.
Further information on the requirements for sprinkler systems can be obtained from your local fire safety department.
