If hood suppression system has activated, what should you do with the extinguisher?

• A. Repurpose one extinguisher into the hood system.
• B. Use another extinguisher in the hood.
• C. Deactivate the hood system and continue.
• D. Do not repurpose; wait for safe clearance and service the area.

Answer: (D)

When a hood suppression system has activated, the priority is safety and proper reset by professionals. The extinguishing agent has been discharged to control the fire, and the area may still be hazardous. You should not repurpose a remaining extinguisher into the hood or try to keep operating; using another extinguisher in the hood is not appropriate because the system needs to be reset and the area inspected. The correct action is to wait for safe clearance and have the area serviced by qualified personnel who can reset the system, check for damage, and ensure everything is safe before resuming operations.
