CFR /  Title 46  /  Part 189  /  Sec. 189.25-20 Fire extinguishing equipment.

(a) At each inspection for certification, periodic inspection, and at such other times as considered necessary the inspector shall determine that all fire-extinguishing equipment is in suitable condition and he may require such tests as are considered necessary to determine the condition of the equipment. The inspector shall determine if the tests and inspections required by Sec. 196.15-60 of this subchapter have been conducted. At each inspection for certification and periodic inspection the inspector shall conduct the following tests and inspections of fire-extinguishing equipment:

(1) All hand portable fire extinguishers and semiportable fire-extinguishing systems shall be checked as noted in Table 189.25-20(a)(1). In addition, the hand portable fire-extinguishers and semiportable fire-extinguishing systems shall be examined for excessive corrosion and general condition.

Table 189.25-20(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, Examine pressure cartridge and

or 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

water, solution, or

antifreeze. Insert charged

cartridge.Carbon dioxide......................... Weigh cylinders. Recharge if

weight loss exceeds 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\.................. ...............................------------------------------------------------------------------------\1\ Cylinders must be tested and marked and all flexible connections and

discharge hoses of semiportable carbon dioxide and halon extinguishers

must be tested or renewed as required in 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

are not permitted.

(2) Fixed fire-extinguishing systems shall be checked as noted in Table 189.25-20(a)(2). In addition, all parts of the fixed fire-extinguishing systems shall be examined for excessive corrosion and general conditions.

Table 189.25-20(a)(2)------------------------------------------------------------------------

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

must have such 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 or 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

that Halon 1301 system approvals

have expired, but that 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. Inspect hoses for damage or

decay. 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) On all fire-extinguishing systems all piping, controls, valves, and alarms shall be checked to ascertain that the system is in operating condition.

(4) The fire main system shall be operated and the pressure checked at the outlets having the greatest pressure drop between the fire pumps and the nozzles which may not always be the most remote and highest outlets. All firehoses 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.
