What should dry chemical stored-pressure extinguishers manufactured after 1984 be subjected to?

Dry chemical stored-pressure extinguishers manufactured after 1984 must be subjected to a 6-year maintenance requirement. This involves having the extinguisher removed from service for detailed inspection and maintenance every six years, which is crucial for ensuring its effectiveness and reliability in case of a fire emergency. During this maintenance, the dry chemical agent is replaced, and the internal components of the extinguisher are checked for wear or damage.

This process is a standardized procedure aimed at maintaining safety standards set by regulatory bodies, which helps to ensure that extinguishers are functioning properly and are ready for use when needed. Following this guideline is critical for ensuring compliance with safety regulations and for the operational readiness of fire safety equipment.
