CFR /  Title 46  /  Part 71  /  Sec. 71.25-20 Fire detecting and extinguishing equipment.

(a) At each annual inspection, the inspector shall conduct the following tests and inspections of fire detecting and extinguishing equipment:

(1) All hand portable fire extinguishers and semiportable fire extinguishing systems shall be checked as noted in table 71.25-20(a)(1). In addition, the hand portable fire extinguishers and semiportable fire extinguishing systems shall be examined for excessive corrosion and general condition.

Table 71.25-20(a)(1)------------------------------------------------------------------------

Type unit Test------------------------------------------------------------------------Soda acid............................... Discharge. Clean hose and

inside of extinguisher

thoroughly. Recharge.Foam.................................... Discharge. Clean hose and

inside of extinguisher

thoroughly. Recharge.Pump tank (water or antifreeze)......... Discharge. Clean hose and

inside of extinguisher

thoroughly. Recharge with

clean water or antifreeze.Cartridge operated (water, antifreeze or Examine pressure cartridge and

loaded stream). replace if end is punctured

or if cartridge is otherwise

determined to have leaked or

to be in unsuitable

condition. Remove liquid.

Clean hose and inside of

extinguisher thoroughly.

Recharge with clean water,

solution or antifreeze.

Insert charged cartridge.Carbon Dioxide.......................... Weigh cylinders. Recharge if

weight loss exceed 10 percent

of weight of charge. Inspect

hose and nozzle to be sure

they are clear.\1\Dry chemical (cartridge-operated type).. Examine pressure cartridge and

replace if end is punctured

or if cartridge is otherwise

determined to have leaked or

to be in unsuitable

condition. Inspect hose and

nozzle to see they are clear.

Insert charged cartridge. Be

sure dry chemical is free-

flowing (not caked) and

chamber contains full charge.Dry chemical (stored pressure type)..... See that pressure gage is in

operating range. If not, or

if seal is broken, weigh or

otherwise determine that full

charge of dry chemical is in

extinguisher. Recharge if

pressure is low or if dry

chemical is needed.Vaporizing liquid \2\ (pump type)....... Pump a few strokes into clean

pail and replace liquid. Keep

water out of extinguisher or

liquid. Keep extinguisher

completely full of liquid.Vaporizing liquid (stored pressure type) See that pressure gage is in

operating range. Weigh or

check liquid level to

determine that full charge of

liquid is in extinguisher.

Recharge if pressure is low

or if liquid is needed.------------------------------------------------------------------------\1\ Cylinders must be tested and marked, and all flexible connections

and discharge hoses of semi-portable carbon dioxide and halon

extinguishers must be tested or renewed, as required by Sec. Sec.

147.60 and 147.65 of this chapter.\2\ Vaporizing-liquid type fire extinguishers containing carbon

tetrachloride or chlorobromomethane or other toxic vaporizing liquids

shall be removed from all vessels. (See Sec. 76.50-5(e) of this

subchapter.)

(2) Fixed fire extinguishing systems shall be checked as noted in table 71.25-20(a)(2). In addition all parts of the fixed fire extinguishing systems shall be examined for excessive corrosion and general conditions.

Table 71.25-20(a)(2)------------------------------------------------------------------------

Type system Test------------------------------------------------------------------------Foam...................... Systems utilizing a soda solution must have

that solution replaced. In all cases,

ascertain that powder is not caked.Carbon dioxide............ Weigh cylinders. Recharge cylinder if weight

loss exceeds 10 percent of the weight of

the charge. Test time delays, alarms, and

ventilation shutdowns with carbon dioxide,

nitrogen, or other nonflammable gas as

stated in the system manufacturer's

instruction manual. Inspect hoses for

damage or decay. Ensure that nozzles are

unobstructed. Cylinders must be tested and

marked, and all flexible connections on

fixed carbon dioxide systems must be tested

or renewed, as required by 46 CFR 147.60

and 147.65.

Halon 1301 and halocarbon. Recharge or replace if weight loss exceeds 5

percent of the weight of the charge or if

cylinder has a pressure gauge, recharge

cylinder if pressure loss exceeds 10

percent, adjusted for temperature. Test

time delays, alarms, and ventilation

shutdowns with carbon dioxide, nitrogen, or

other nonflammable gas as stated in the

system manufacturer's instruction manual.

Inspect hoses for damage or decay. Ensure

that nozzles are unobstructed. Cylinders

must be tested and marked, and all flexible

connections to Halon 1301 and halocarbon

cylinders must be tested or renewed, as

required by 46 CFR 147.60 and 147.65 or

147.67.

NOTE: Halon 1301 system approvals have

expired, but existing systems may be

retained if they are in good and

serviceable condition to the satisfaction

of the Coast Guard inspector.Inert gas................. Recharge or replace cylinder if cylinder

pressure loss exceeds 5 percent of the

specified gauge pressure, adjusted for

temperature. Test time delays, alarms, and

ventilation shutdowns with carbon dioxide,

nitrogen, or other nonflammable gas as

stated in the system manufacturer's

instruction manual. Ensure that nozzles are

unobstructed. Cylinders must be tested and

marked, and all flexible connections on

fixed inert extinguishers must be tested or

renewed, as required by 46 CFR 147.60 and

147.66.Water mist................ Maintain system in accordance with the

maintenance instructions in the system

manufacturer's design, installation,

operation, and maintenance manual.------------------------------------------------------------------------

(3) All fire detecting and extinguishing systems, all piping controls, valves, and alarms shall be checked to ascertain that the system is in operating condition. In this respect, automatic sprinkling systems shall be checked by means of test stations or opening heads, smoke detecting systems shall be checked by introducing smoke into the accumulators, fire detecting and manual alarm systems shall be checked by test stations or actuating detectors or pull boxes, and steam smothering lines shall be checked with at least a 50 p.s.i. air pressure with the ends capped or by blowing steam through the lines at the designed pressure.

(4) The fire main system shall be operated and the pressure checked at the most remote and highest outlets. All fire hose shall be subjected to a test pressure equivalent to the maximum pressure to which they may be subjected in service, but not less than 100 p.s.i.
