DESCRIPTION AND OPERATION

1. Description

A. The portable halon fire extinguishers have an aluminum cylinder, a pressuregauge, and a valve assembly. Fire extinguishers 466040 and 466090 also havea hose assembly. Fire extinguisher 898052 has only a nozzle assembly. Thehand-operated valve assembly, pressure gauge, hose, and nozzle are installedon the top of the cylinder as shown in Figure 1. A pull-out pin and a pull-tite sealprevent the fire extinguisher from being operated accidentally.

B. The fire extinguisher cylinder is filled with a liquid fire-extinguishing agent, Halon1211 (Bromochlorodifluoromethane [CBrClF2)]. The cylinder is pressurized withnitrogen (N2). The valve assembly is attached to the cylinder neck. The pressuregauge is attached to the valve body, and continuously monitors the pressure in-side the cylinder. The valve body gives a method to connect a recharge line tothe fire extinguisher as well as to discharge the extinguishing agent. The hose as-sembly, or nozzle, as applicable, are attached to the valve assembly.

C. A heavy duty mounting bracket is required when the portable fire extinguisher isinstalled in an aircraft, boat, or other movable vehicle. This mounting bracket isnot supplied with the fire extinguisher. It must be purchased separately. See Ta-ble 1, Specified Data for the correct mounting bracket.

2. OperationA. The fire extinguisher is pressurized with nitrogen to get the force that is neces-

sary to push the extinguishing agent from the cylinder. The extinguishing agentand the nitrogen are kept in the cylinder by the valve assembly until the lever ismanually operated.

B. When the lever is pushed down, the valve stem assembly inside the valve bodyis also pushed down. The nitrogen forces the extinguishing agent through the si-phon tube, around the stem assembly, through the valve assembly, and hose ornozzle assembly.

TESTING AND FAULT ISOLATION

1. General

A. In the United States, it is mandatory (refer to the United States OccupationalSafety and Health Administration [OSHA] regulations) to do a hydrostatic (proofpressure) test of the cylinders at intervals of twelve years (refer to OSHA 29 CFR1910.157[f] and Table L-1).

B. Walter Kidde recommends you do a hydrostatic test at twelve year intervals (re-fer to 29 CFR 1910.157[f] and Table L-1, and CGA Pamphlet C-1)

C. This section contains the procedures, materials and equipment necessary to dothe tests of the fire extinguishers, and to find the defective parts. Do the visualchecks, leak tests, and the necessary repairs before you do the hydrostatic tests.See IPL Figures 1, 1A, and 1B for the location of the fire extinguisher parts.

D. Unserviceable components must be found during the tests. Refer to Table 102.

2. Test Equipment and Materials

The necessary test equipment and materials are given in Table 101. You can use al-ternative equipment and materials if the measurement accuracy and material life isnot decreased. All calibrated equipment must have a current calibration approval.

3. Weight Check

NOTE: The weight check instructions in this manual supersede theinstructions on the nameplate.

NOTE: Weigh the complete fire extinguisher assembly. This includesthe pull-out pin, pull-tite seal, and hose assembly with hosestrap, or nozzle (as applicable).

A. Put the fire extinguisher on the scale. Record the weight.

B. Remove the fire extinguisher from the scale.

NOTE: If the last recorded weight is not marked on the cylinder, usethe weight limits in Table 1, Specified Data to determine theallowable weight.

C. Compare the weight you got in step A. to the gross weight from the last time thefire extinguisher was charged. If the weights are the same there is no leak.

D. If the weight you got in step A. is less than 1% of the gross, disassemble and re-pair the fire extinguisher, as necessary. Refer to DISASSEMBLY and REPAIR.

E. After you weigh the fire extinguisher, Walter Kidde recommends you write theweight on a locally approved label attached to the cylinders surface.

4. Leak Test

A. Do the halon leak test with an H-25C Halogen Leak Detector or equivalent, cali-brated to 1 x 10-5 Std cc/second. Do the halogen leak test as follows:

(1) Make sure the leak detector is calibrated as specified in the operating in-structions.

(2) Use the detector probe to find if the air in test area contains halon. Refer tothe operating instructions for the leak detector.

(3) Continue to do the leak test on all areas of the fire extinguisher.B. The total values for all leaks must be less than 1 x 10-5 Std cc/second. If the leak-

age is too much, remove the valve assembly and repair as necessary. Refer toTable 102, Fault Isolation and DISASSEMBLY and REPAIR.

CAUTION: NEVER TORQUE THE VALVE ASSEMBLY TO STOP ALEAK. YOU CAN CAUSE DAMAGE TO THE FIRE EXTIN-GUISHERS COMPONENTS OR SEALING SURFACES.

26-21-39 Page 102Mar 15/02

466040, 466090, 898052


5. Hydrostatic Test

CAUTION: BE CAREFUL WHEN YOU DO THE HYDROSTATIC TEST.ACCURATELY FIND THE AMOUNT OF CYLINDER DIS-TORTION. DISCARD THE CYLINDER IF THE WALLS AREDANGEROUSLY THIN. DO NOT DISCARD THE CYLIN-DER IF THE THICKNESS IS CORRECT.

NOTE: Do the hydrostatic test by the proof pressure method speci-fied in the Compressed Gas Association (CGA) Pamphlet C-1. Test personnel must know the contents of CGA PamphletC-1 to help make an analysis of the results correctly. Thereare conditions when a cylinder must not be hydrostaticallytested. Refer to NFPA-10 for these conditions.

A. Prepare to do the hydrostatic test

(1) Remove the valve assembly and all internal parts from the fire extinguisher.Refer to DISASSEMBLY.

(2) Only test persons are permitted in the test area during hydrostatic tests.WARNING: CONCENTRATION OF COMPRESSED AIR OR UN-

WANTED MATERIAL MOVED BY COMPRESSED AIRCAN CAUSE INJURY TO PERSONS. ALWAYS POINTCOMPRESSED AIR AWAY FROM PERSONS. USE APPLI-CABLE EYE PROTECTION TO PREVENT INJURY TOYOUR EYES.

(3) Clean the cylinder neck with dry air or nitrogen with a maximum pressure of30 psig (207 kPa).

(4) Install the hydrostatic test adapter (877635) in the cylinder neck.B. Hydrostatic Test Procedure

(1) Install the cylinder in the test setup shown in CGA Pamphlet C-1.(2) Fill the cylinder with water through the open test adapter (877635). When

the water begins to come out of the test adapter (this shows that all the airhas been removed from the cylinder), fully tighten the test adapter.

(3) Turn off the water supply.(4) Attach the pressure line of the test setup to the hydrostatic test adapter in

the cylinder neck.

(5) Pressurize the cylinder. Refer to Table 1, Specified Data, for the correct testpressure.

26-21-39 Page 103Aug 31/98

466040, 466090, 898052


(6) Do the hydrostatic test. Refer to CGA Pamphlet C-1 and NFPA-10 for thecorrect procedures.

(7) Do a visual inspection of the cylinder. Look for any signs of distortion or leak-age. There must be no distortion or leakage and the test pressure must notdecrease.

(8) Release the air pressure and remove the cylinder from the test setup.(9) Use a locally approved method (tag, label, ink stamp, etc.) to write on the ex-

tinguisher the date the hydrostatic test was done. Do not metal stamp thedate onto the cylinder.

2. Definitions

A. The definitions that follow are applicable to this section.

(1) DentsDents are deformations of the cylinder caused by a blunt object and doesnot cause the wall thickness to be decreased.

(2) Cuts, Gouges, Digs, and ScratchesThese are damage which cause loss of wall thickness and are caused bysharp objects that cut into the metal.

(3) Corrosion(a) Corrosion is the loss of thickness by some corrosive effect. It usually

shows as general corrosion or pitting corrosion.

(b) General corrosion shows a uniform loss of wall thickness in a large area.(c) Pitting corrosion can be small and localized or large and scattered.(d) Line corrosion is a series of pits closely spaced which appear to be in

line. This condition is more serious than isolated pitting.

(4) BulgesBulges are irregular surface dimensions on part of the cylinder. Bulges usu-ally occur because of too much pressure or because the cylinder becametoo hot.

3. Inspection

A. Visually examine the fire extinguisher for damage, dents, scratches, gouges,nicks, and loose or damage components.
