Fire Protection; Extinguishing - Piper PA-44-180 SEMINOLE Maintenance Manual

GENERAL.
This chapter contains information pertaining to basic information data, maintaining and servicing of the
portable fire extinguisher unit installed on the PA-44-180, s/n's 44-7995001 thru 44-8195026, and the PA-44-
180T, s/n's 44-8107001 thru 44-8297020.

EXTINGUISHING.

The portable fire extinguisher unit (Model No. 2-10), contains 2 pounds of Halon 1211. It has a discharge
rate of no less than 8 seconds and no more than 10 seconds. The original weight of the extinguisher is 4
pounds 14 ounces ± 2 ounces.
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. Slide the (red) safety catch down with the thumb, direct the
nozzle towards the base of the fire source, squeeze the lever with the palm of the hand. When you squeeze the
lever, an indicator disc is ejected from the rear of the operating head of the extinguisher, and extinguishant is
released from the nozzle in a wide, flat pattern. Maximum extinguishing effect is obtained if the fire-fighter
keeps moving in towards the base of the fire source as it is extinguished. Releasing the lever closes a
s e condary 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. Ejection of
the indicator disc provides visual indication of partial or total discharge. A partly or totally discharged charge
assembly should be replaced immediately after use.
The extinguisher shall be inspected monthly or unless otherwise specified intervals. The nozzle shall be
examined to ascertain that they are unobstructed. The tamper tag or tamper indicator shall be intact. The
extinguisher shall be pressurized as intended and weight shall be within tolerance on the label. Weigh at
i n t e rvals of not more than 12 months in accordance with N.F.P.A. standard no. 10.
AFTER DISCHARGE OF EXTINGUISHER AVOID EXPOSURE
TO SMOKE, VAPORS AND OTHER BY-PRODUCTS OF FIRE.
PRESSURE VESSEL. PROTECT FROM CORROSIVE
CONDITIONS; IF THERE IS ANY CORROSION OR
DAMAGE, EXTINGUISHER SHOULD BE CAREFULLY
EMPTIED AND DISCARDED. USE ONLY AS DIRECTED.
