How often do wet agent extinguishers require hydrostatic testing?

Wet agent extinguishers typically require hydrostatic testing every five years. This testing is crucial for ensuring the integrity and safety of the extinguisher’s container, which can be affected by factors such as pressure changes and corrosion over time. By having this test conducted every five years, technicians can verify that the extinguisher is still capable of operating effectively and safely in the event of a fire.

This timeframe is established in industry regulations and standards, such as those from the National Fire Protection Association (NFPA), which provide guidelines on the maintenance and inspection of fire extinguishers. Understanding this interval helps ensure compliance with safety regulations and contributes to overall fire safety management.
