Hi,
our main hazards are class A paper fire and electrical fires. I understand the consensus is 30m maximum distance between class A extinguishers but what about electrical fires. Some sources appear to recommend no more than 10m which would be over the top for our needs.
Is there a definitive guide somewhere?
Thanks

CdC - please do not believe any fire extinguisher salesperson 30m is maximum distance between Class A extinguishers. This happened to my predecessor and the salesperson made a killing. we have removed hundreds since then! The 'Guideline' is 60m but you can adjust this based on your fire RA. The same applies to Co2 units.
We have 50 plus educational buildings on our estate and if we followed (even the corrected guidelines) it would be like day of the triffids. Our assessments do take into account the extinguisher ratings and floor areas but there is also a little flexibility there and we are still well covered.

Alister took the words out of my mouth - risk assess it.

While I agree with the notion of risk assessment, I did find this from BS5306-8/2012
9.3 Distribution of extinguishers for fires involving live electrical equipment
Extinguishers of a type marked as suitable for use on fires in live electrical equipment should be sited near any electrical equipment (see also 5.4.2).
9.4 Travel distance
Extinguishers provided to deal with fires involving electrical equipment should be sited near to the fire hazard concerned, but not so near as to be inaccessible
or to place the operator in undue danger in case of fire. The travel distance should be not more than 10 m.
mhmm... food for thought

Remember it is 'only' a BS and we need to consider what an electrical fire hazard is - I would agree near distribution boards etc but if we are inferring that all electrical equipment is a fire hazard such as office equipment we would be overrun with Co2s. To draw some sort of parallel, read the case study about PAT testing of office equipment in the HSE's offices.
