Does steam supplied from an external source require shutdown upon actuation of a protection system?

The assertion that steam supplied from an external source does not require shutdown upon actuation of a protection system is accurate due to the operational principles of dry chemical extinguishing systems. These systems are designed to suppress fires primarily through the discharge of dry chemical agents, which effectively interrupt the combustion process without necessitating the simultaneous shutdown of external services such as steam.

In many applications, especially those involving industrial processes, steam may still be required for operational continuity, safety, or to prevent equipment damage. The actuation of a dry chemical system mainly focuses on extinguishing a fire rather than affecting external utilities like steam. Therefore, the operational integrity of steam systems can often remain intact while ensuring that fire protection measures are actively functioning.

This understanding emphasizes that the dry chemical extinguishing system should be able to operate independently of the steam supply, ensuring both fire safety and process reliability can coexist.
