Under what condition should a fire extinguisher be condemned?

A fire extinguisher should be condemned if it has corrosion or broken threads. This condition indicates that the integrity of the extinguisher has been compromised, which can severely affect its effectiveness during an emergency. Corrosion can weaken the metal casing, leading to the risk of rupture or leakage when the extinguisher is pressurized and in use. Broken threads can prevent the nozzle or hose from securely attaching, which hinders the proper deployment of the extinguishing agent. Both situations create a significant safety hazard, making it imperative that any extinguisher exhibiting such issues be removed from service and condemned to ensure that it does not pose a danger to users in critical situations.
