What should be done if a dry chemical extinguishing system is activated?

When a dry chemical extinguishing system is activated, it is essential to inspect the system, recharge it if necessary, and conduct testing before returning it to service. This procedure ensures that the system remains functional and reliable for future fire emergencies. After activation, the dry chemical agent used to extinguish the fire is expended, which means that without recharging, the system cannot provide protection if a subsequent fire occurs.

Additionally, inspecting the system allows for identification of any potential damages or malfunctions that occurred during the activation and ensures that all components are in working order. Testing the system afterward helps confirm that it operates correctly and meets the necessary performance standards outlined in NFPA 17. Thus, following this approach safeguards against the risk of system failure in critical situations.
