It covers commissioning, basic servicing, the extended service, overhaul procedures and recharges. Commissioning Once your new fire extinguisher arrive at your premises, they need to be checked and properly set up, ready for use. Heaver extinguishers need their handles 1m above floor level. Where wall mounting is not appropriate or possible, you can also position extinguishers on a stand or plinth that raises them to the correct level.

Basic Service A regular visual check each month should be made to ensure fire extinguishers have not been discharged and are in good repair. Your extinguishers also require a basic service check every year, which may include replacement of parts if required. Extended Service, Overhaul Procedures And Recharges Extended servicing and overhauls are required at set intervals, although it may be more cost-effective to actually replace extinguisher rather than pay the overhaul and recharging costs.

Indeed, many smaller businesses find that it might be cheaper and more efficient to replace the few extinguishers they have rather than pay the cost of annual maintenance checks. The BS also gives guidance on disposal of disused or condemned fire extinguishers. BS Part 8 This part gives guidance on the selection and positioning of portable fire extinguishers, and is perhaps the more useful of the two documents.

It stresses the importance of early planning, environmental considerations, and training. This part of the Standard also addresses important considerations such as the type of extinguishers available, the types of fires they can be used on, and the operational temperature ranges.

When choosing an appropriate fire extinguisher, you need to consider: The distance and direction of discharge i. How far it will reach or spread Its electrical conductivity or not The effect of powder extinguishers when discharged in inside spaces When positioning your fire extinguishers, you need to consider: Ease of access Security of fixings or stands Visibility and proximity to escape routes Consistency of locations on different floors Ensuring the best extinguisher for the job is the first to hand When mounting your fire extinguishers, you need to ensure: All size of extinguishers are the correct height from the floor Extinguisher mounts are securely fixed in place Any extinguisher can be quickly removed to use in an emergency The extinguisher is no more than a set distance from any possible fire i.

More than 30metres from a Class A fire All extinguishers are protected against corrosion and vandalism — consider fire extinguisher boxes and jackets, plus anti-tamper seals Minimum Fire Extinguisher Quantities The BS defines both the travel distance i.

It is worth remembering that these are minimum requirements; your own Fire Risk Assessment may identify the need for more extinguishers, but should never specify less than the minimum. For example, in a Class A risk area such as an office, reception or file store with a floor area of up to square meters, you should provide at least 2 extinguishers with a total fire rating of 26A.

The Standard gives minimum requirements for all classes of fire, and also includes examples for locations where more than one fire risk exists, such as manufacturing premises with a kitchen area. In the UK, there is no separate class for fires involving electrical equipment, as technically electricity does not burn, but instead can cause other materials to ignite.
