What action is required for gas appliances not needing protection when an extinguishing system is activated?

When an extinguishing system is activated, gas appliances that do not require protection must be automatically shut off to ensure safety and prevent potential hazards. This action is designed to mitigate the risk of gas leaks or explosions that could occur if the appliances continue to operate while the extinguishing system is discharging.

Automatic shutoff ensures that gas flow is halted immediately, thereby protecting personnel and property from potential dangers associated with an active fire or discharge of the extinguishing agent. This measure is critical because the focus in a fire situation is not only on extinguishing the flames but also on ensuring that the environment is safe following the activation of the system.

Overall, the requirement for automatic shutoff is a safety standard aimed at reducing the likelihood of risk from gas appliances during emergency situations when the extinguishing system is engaged.
