After a discharge, which action belongs in proper follow-up procedures?

• A. Shut off power to the system and wait for supervisor approval.
• B. Refill/recharge the agent, inspect for damage, reset the system, and conduct acceptance tests.
• C. Ignore the discharge event and continue operation.
• D. Disassemble the entire hood and ductwork.

Answer: (B)

After a discharge, the system must be brought back to operating condition through a complete follow-up: refill or recharge the extinguishing agent, inspect for any damage or leaks in cylinders, hoses, and components, reset the system so it’s ready for service, and run acceptance tests to confirm proper discharge, alarm, and overall readiness.

Refilling the agent is essential because the system cannot function again until it’s replenished to its configured amount. Inspecting for damage ensures there are no compromised parts that could fail during a future discharge. Resetting clears fault indicators and re-arms the system so it can respond correctly if another event occurs. Acceptance testing verifies that everything operates as intended—from the agent release to the detection and signaling components—so the protection is reliable.

Shutting off power and waiting for supervisor approval, ignoring the discharge, or disassembling the hood and ductwork do not align with proper follow-up and leave the system unsafe or unnecessarily disrupted.
