What does a fire extinguisher undergo annually?

A fire extinguisher undergoes a maintenance check annually to ensure it is in proper working condition and compliant with safety standards. This maintenance check involves a comprehensive evaluation of the extinguisher's overall status, including examining the physical condition, testing the pressure gauge, checking the safety seal, and ensuring that there are no signs of corrosion or damage.

The purpose of this annual maintenance is to identify any issues that could affect the extinguisher's functionality during an emergency, allowing for necessary repairs or servicing to be performed. This proactive approach helps ensure the extinguisher will function effectively when needed.

The other activities listed, such as full inspections, replacement checks, and refilling procedures, may also be part of fire extinguisher maintenance, but they do not specifically occur on an annual basis or are part of distinct service intervals or events that are not exclusive to yearly checks. By focusing on the annual maintenance check, the key aspects of functionality and safety are prioritized, aligning with established fire safety protocols.
