How frequently should hydrostatic testing be conducted on most extinguishers?

Hydrostatic testing of fire extinguishers is a critical maintenance procedure designed to ensure their structural integrity and reliability in emergency situations. Most extinguishers require hydrostatic testing every 5 years as part of their maintenance routine. This testing involves subjecting the extinguisher to a pressure greater than it would experience during normal operation, helping to detect any potential leaks, weaknesses, or other safety hazards that could compromise the unit's effectiveness.

Conducting the test every 5 years aligns with national safety standards and manufacturer recommendations, ensuring that extinguishers remain safe and fully operational for use in case of a fire. This schedule of testing is part of a broader preventative maintenance strategy aimed at protecting lives and property from fire hazards by ensuring that all fire safety equipment functions properly when needed.
