Posted By Jon H Hi Elliot, this is from the governments fire safety risk assessment guide - available fro free download. http://www.communities.g...ocuments/fire/pdf/151543 Section 3 - page 58 Where the fire risk is not confined to a particular location, e.g. Class A fires, the fire extinguishers should be positioned on escape routes, close to the exit from the room or floor, or the final exit from the building. Similarly, where the particular fire risk is specifically located, e.g. flammable liquids, the appropriate fire extinguisher should be near to the hazard, and located so that it can be safely used. They should be placed on a dedicated stand or hung on a wall at a convenient height so that employees can easily lift them off (at about 1m for larger extinguishers, 1.5m for smaller ones, to the level of the handle). Ideally no one should have to travel more than 30m to reach a fire extinguisher. If there is a risk of malicious use you may need to use alternative, and more secure, locations. Hope this helps. Jon

Posted By Ashley Wood The recommendation is 1000mm from floor to top of handle for water, foam, 5kg Co2 and 1400mm for Co2 -3kg. However, as pointed out consider the ability of the user as they will have to lift the full weight to clear the bracket holding the extinguisher.
