What action must be taken when any protection system is actuated?

When any protection system, such as a dry chemical extinguishing system, is actuated, it is essential to shut down all fuel or heat sources to appliances. This action helps to mitigate the risk of re-ignition of the fire, ensuring that all potential sources of flames or heat are eliminated. By doing so, you create safer conditions that allow for the fire to be effectively managed and extinguished without the danger of further fuel feeding the fire.

This procedure is critical following the activation of a fire suppression system. It helps to fully minimize hazards and protects both responders and occupants from additional dangers associated with a potentially reignited fire. This proactive step also assists fire service personnel in their efforts to safely control and eventually extinguish the situation.
