What is a consequence of exceeding the hydrostatic test interval?

Exceeding the hydrostatic test interval for a fire extinguisher can lead to a potential malfunction of the extinguisher. Hydrostatic testing is critical for assessing the integrity and structural soundness of the cylinder that contains the extinguishing agent. Over time, pressure and environmental factors can weaken the cylinder, leading to risks such as leaks or ruptures. If the test interval is neglected, the extinguisher may not function properly during an emergency, resulting in a failure to extinguish a fire effectively. This underscores the importance of adhering to maintenance schedules and testing intervals to ensure safety and reliability in fire-fighting equipment.
