Clause 7.4 of BS 5306-8:2023* states class C fires as “Fires involving gases.”

Clause 7.4.1 states “Extinguishers should not normally be provided to tackle class C fire hazards.

When the fire risk assessment determines that extinguishers should be provided to tackle a class C fire hazard (most likely in high-risk, industrial locations by specially trained personnel}, the risk assessment should determine the type and number of extinguishers required. Extinguishers with a class C fire rating should then be provided as identified in the fire risk assessment.”

BAFE SP101 Registered Organisations will be able to advise the Responsible Person (i.e. the customer) on suitable fire extinguishers for their premises that meet all the requirements of BS 5306-8 and the BAFE SP101 Scheme (which includes additional parts of BS 5306 to also be followed).
