What is the preflight for the portable Halon fire extinguisher?

• A. Gauge green area, pin & seal intact, hose not cracked or frayed (when present), secure in bracket
• B. Gauge red area, pin missing, hose cracked
• C. Gauge green area, pin missing, hose present
• D. Gauge yellow area, pin intact, hose cracked

Answer: (A)

The preflight check for a portable Halon extinguisher focuses on ensuring it is charged, unaltered, and ready for immediate use, and that it will stay in place where needed. Specifically, the gauge should be in the green area, indicating a pressurized unit that’s ready to discharge. The safety pin and tamper seal must be intact, showing the extinguisher hasn’t been used or tampered with. The hose should be free of cracks or frays if present, so there’s no leak or obstruction, and the extinguisher should be securely mounted or bracketed so it won’t move or fall during ground operations. When all these conditions are met, the extinguisher is considered serviceable and accessible. If the gauge were in the red area, the unit would not be ready due to low or no pressure. A missing pin or broken tamper seal suggests it has been used or tampered with. A cracked hose indicates damage and risk of failure, and an unsecured extinguisher could become a hazard or not be readily available when needed.
