When should you replace a fire extinguisher?

A fire extinguisher should be replaced when it is empty because an empty extinguisher will not be able to suppress a fire effectively. Regular checks should be made to ensure that the extinguisher is fully charged, which is indicated by the gauge. If the gauge shows that the extinguisher is empty, it is no longer functional and must be replaced.

Additionally, an expired inspection sticker indicates that the extinguisher has not been checked for a significant period, which could mean that it may not function correctly in case of a fire. Regular inspections ensure that everything is in working order, including checking for physical damage, proper pressure levels, and expiration dates. If the inspection sticker is expired, it is a strong indication that the extinguisher should be replaced or serviced.

Thus, both circumstances — an empty extinguisher and an expired inspection sticker — necessitate replacement to ensure effective fire safety measures.
