When is hydrostatic testing of fire extinguishers required?

Hydrostatic testing of fire extinguishers is required according to a prescribed test schedule, which is established by safety standards and regulations. This schedule ensures that fire extinguishers are regularly assessed for their structural integrity and functionality. The primary purpose of hydrostatic testing is to verify that the cylinder can safely hold pressure and is free from leaks, ensuring that the extinguisher will operate effectively in the event of a fire.

Different types of extinguishers may have different schedules for hydrostatic testing, often outlined by the National Fire Protection Association (NFPA) or local regulations. This testing is not simply performed at arbitrary intervals but is based on specific guidelines that take into account the type of extinguisher and its usage. It is essential to adhere to these schedules to maintain compliance and ensure safety in workplaces and environments where extinguishers are critical for fire protection.
