EXTINGUISHER
A portable Halon
1211 (Bromochlorodifluoromethane) fire
extinguisher is standard and is installed on the
floorboard near the
pilot's
seat
where it would
be
accessible
in case of fire. The
extinguisher has an Underwriters Laboratories
classification of 5B:C.
If installed, the extinguisher should be checked
prior

bottle, is within the green arc (approximately 125 psi) and the
operating lever lock pin is securely in place.

the
fire extinguisher:
1. Loosen retaining clamp(s) and remove extinguisher from
bracket.
2.
Hold extinguisher upright, pull operating ring pin,
and press

while directing
the discharge
at
the base

at
the
