What is the required testing frequency for stored pressure extinguishers that exceed 40 lbs?

Stored pressure extinguishers that exceed 40 lbs are required to be subjected to a thorough inspection and testing every 12 years. This testing ensures that the extinguishers continue to function effectively and safely when needed. During this 12-year interval, a detailed examination of the extinguisher's physical condition, pressure integrity, and operational reliability is conducted.

It is crucial for these extinguishers to be maintained properly, and the 12-year frequency aligns with safety guidelines that ensure they are recharged and pressure tested to guarantee they can perform effectively in an emergency. Adhering to this testing schedule plays a significant role in preventing malfunctions and ensuring readiness for firefighting situations. Regular checks and servicing are essential to uphold safety standards and compliance with fire safety regulations.
