Portable Fire Extinguisher
A. Description
A portable, disposable, Class 2B:C fire extinguisher (Model No. A600) is installed as standard
equipment. Containing 1.2 lbs. (550 grams) of Halon 1211/1301 blend, the extinguisher is located
either in the top of the right-hand pyramid cabinet (if installed) or on the floor just aft of the spar
carry thru and behind the co-pilot’s seat (see Figure 1). When floor-mounted, the extinguisher is
secured by a quick release bracket.
To operate the extinguisher, remove it from the quick-release bracket, hold it upright in either hand
by the handgrip, with the spray nozzle pointing forward. Remove the safety pin, direct the nozzle
towards the base of the fire source, depress the lever. Maximum extinguishing effect is obtained if
the fire fighter uses side to side motion and keeps moving in towards the base of the fire source as
it is extinguished. Releasing the lever closes a secondary seal inside the operating head. This
interrupts the flow of extinguishant, thus retaining part of the charge, for dealing with a flash back or
re-ignition should they occur, without waste or leakage. A partly or totally discharged extinguisher
should be replaced immediately after use.
B. Inspection
Disposable type fire extinguishers should be maintained and inspected in accordance with the
nameplate instructions.
(1) Monthly
Inspect monthly or more frequently. Ensure nozzle is not obstructed and safety seal is intact.
Inspection is a "quick check" that an extinguisher is available and will operate. It is intended to
give reasonable assurance that the extinguisher is fully charged and operable. This is done by
seeing that it is in its designated place, that it has not been actuated (discharged) or tampered
with, and that there is no obvious physical damage or condition to prevent operation.
Determine fullness by weighing or "hefting."
(2) 100 Hour / Annual
Each 100 hours or annually, whichever comes first, weigh the extinguisher. Replace and return
to manufacturer if gross weight is below the minimum specified on the nameplate.
