Study Notes

Halon 1211 Fire Extinguisher

Weighs 1.25 lbs. (567 grams) and contains Halon 1211.
Storage location: atop the tunnel cover, just forward of the spar box.
Secured in place by a quick release bracket for easy access.

Operation Procedure

To operate, remove the extinguisher from the bracket and hold it upright by the handgrip, with the nozzle pointing forward.
Remove the safety pin to enable operation.
Aim the nozzle at the base of the fire source for effective extinguishing.
Depress the lever to release the extinguishant.
Employ a side-to-side motion while moving towards the fire base for maximum effect.

Re-ignition Management

Releasing the lever activates a secondary seal in the operating head.
This seal interrupts the flow of extinguishant, helping retain some charge for potential flashback or re-ignition incidents.
Important to minimize waste and leakage during use.

Post-Use Protocol

The extinguisher should be replaced immediately after it has been partially or fully discharged to ensure readiness for future incidents.
