Which standard must fire-extinguishing systems comply with?

Fire-extinguishing systems, specifically those that utilize dry chemical agents, must comply with the ANSI/UL 1254 standard. This standard addresses the requirements for the construction, performance, and testing of dry chemical extinguishing systems, ensuring that they effectively suppress fire hazards.

Complying with ANSI/UL 1254 means that a fire-extinguishing system has undergone rigorous testing to demonstrate its reliability in a fire emergency. It ensures that the system meets safety and performance criteria, which is critical for the safety of both the users and the environment.

The other standards listed pertain to different types of products or systems within the fire protection domain but do not specifically cover the parameters for dry chemical extinguishing systems. This distinction is crucial as it underscores the importance of selecting the appropriate standard in accordance with the type of fire-extinguishing system being considered or installed.
