When is a fire extinguisher no longer good?
A fire extinguisher is no longer “good” when the chemicals within the extinguisher lose their charge, or when the pressure of the contents has fallen. The exact shelf life of every fire extinguisher varies from manufacturer to manufacturer and whether it is rechargeable or disposable.
How do you know if a fire extinguisher is safe?
Perhaps the most important factor is the hydrostatic test. Hydrostatic testing measures the integrity of the fire extinguisher’s cylinder, which is under constant pressure. If an extinguisher fails this test, it is unsafe and should be taken out of service immediately.
How often should a fire extinguisher be recharged?
Hydrostatically test dry chemical extinguishers every 12 years. If the canister passes the test, it can be recharged and put back into service. Continue with monthly maintenance and yearly inspections, and conduct hydrostatic testing in another 12 years.
