What maintenance activity should be performed if the extinguisher has been used?

When a fire extinguisher has been used, it is essential to inspect and service it to ensure it functions correctly in case of future emergencies. This maintenance activity includes checking for any damage, ensuring that all parts are intact, and determining whether it needs to be recharged or repaired.

Servicing the extinguisher after use is critical because even if it appears to have some remaining charge, the pressure may have been compromised or the extinguishing agent may not be effective. This proactive approach not only ensures the extinguisher is operational but also adheres to safety regulations and standards.

Regular inspections and maintenance help extend the lifespan of the extinguisher and maintain safety standards, which is why servicing it promptly after any use is crucial.
