Which component is used to prevent accidental discharge on a fire extinguisher?

• A. Carrying Handle
• B. Discharge Locking Pin and Seal
• C. Data Plate
• D. Discharge Nozzle

Answer: (B)

The ability to prevent accidental discharge comes from the discharge locking pin and seal. This safety device is a tamper‑evident pin that keeps the trigger or lever from moving; until you pull the pin and remove the seal, the extinguisher won’t release any agent. The seal also shows at a glance whether the extinguisher has been used or tampered with, which helps during inspections and storage. Once the pin is removed and the seal is broken, you can operate the lever to discharge through the nozzle. The other parts—the carrying handle, data plate, and discharge nozzle—serve transport, information, and the actual outlet, respectively, but they don’t prevent accidental discharge.
