Which statement best describes what must be done with energy sources upon extinguishing system activation?

• A. All energy sources must be shut off
• B. Only electrical sources shut off
• C. Only fuel sources shut off
• D. No action required

Answer: (A)

When a fire suppression system activates, cutting all energy sources is essential to prevent any remaining power or fuel from sustaining or rekindling a fire. Shutting off electrical power stops equipment from acting as ignition sources or causing electrical hazards, and closing fuel or gas supplies removes potential fuel that could feed the fire after the agent is released. Turning off only one type of energy leaves a remaining source that could still contribute to danger or re-ignition, and doing nothing leaves all risks in place. By removing both electrical and fuel sources, you create a safer environment for the extinguishing effort and for responders. After this, follow your standard procedures for securing the area and re-entering.
