What happens to all sources of fuel and electric power when a cooking equipment fire-extinguishing system is activated?

When a cooking equipment fire-extinguishing system is activated, all sources of fuel and electric power are shut down to prevent the fire from escalating and to ensure that the extinguishing agent can effectively suppress the fire. This action is critical because turning off fuel sources stops the supply that could potentially fuel the fire, while shutting down electric power reduces the risk of electrical hazards and prevents any possibility of ignition due to electrical components.

It's essential for fire suppression systems in cooking operations to have this capability as part of their design to ensure maximum safety and effectiveness during a fire event. This procedure minimizes the risk of rekindling and protects both personnel and property by eliminating any possible sources of ignition or fuel. Therefore, the answer clearly emphasizes the importance of shutting down these systems when a fire suppression system is activated.
