good day, my name is dale watts, i run my own fire extinguishers coampny, i have stumbled upon this site and seen a few threads that i have put information on, think i can help you here as well. below is a exact extract from my service manual that we use as guidelines for installing equipment. you will need some sort of cover for fire involving electrics. Also do you stoe any flammable liquids?
EXTINGUISHER COVER
CLASS 'A' FIRE PROVISION: The basic scale of provision for Class A
extinguishers is that, on each storey, there should be at least 2
extinguishers. The total Class A rating should be not less than
0.065 X floor area (in square metres) and not less than 26A. This
minimum requirement corresponds to a floor area of 400 square
metres. However, in the case of buildings in single occupancy with
upper floor area not exceeding 100 square metres the minimum
aggregate rating required for these floors is 13A, and there need
not be 2 extinguishers per floor on the upper floors.
Example
30m x 20m = 600 square metres
x 0.065
39 class A rating
In the above example the following options are available:-
2 X 21A rated extinguishers
3 X 13A rated extinguishers
5 X 8A rated extinguishers
fire ratings are shown on the extinguisher. hope i helped you out. You only have to cover what is actually there. With A sprinkler system, some places, one i know of being a school have not installedany extinguishers as under there risk assessment have said they do not need them. This has caused problems though. As insurance companies do insist on poratble extinguishers to be sited and maintained. If you require info on class 'B' fire then contact me on
