It's not recommended to utilize water to extinguish fire caused by a flammable fluid.
3. Course C extinguishers
A course C extinguisher can be utilized to put out fires caused by electrical equipment/gear such as defective circuit breakers, damaged wiring, fuse boxes, energized electrical components, and also malfunctioning power outlets.

Fire Extinguisher Servicing
Besides evaluation, fire extinguishers require regular servicing by qualified individuals. This includes:
• Hydrostatic testing using water or a non-compressible fluid
• Recharging as per inspection referrals, or if the extinguisher calls for covering up after usage
• Substitute of malfunctioning components that do not function as anticipated
Portable fire extinguishers offered or installed in buildings in the US have to follow the NFPA 10 criterion. This requirement is comprised of standards on option, setup, maintenance, evaluation, and hydrostatic testing of extinguishers.
