  • .10 if cylinders are installed inside the protected space, verify the integrity of the double release lines inside the protected space, and check low pressure or circuit integrity monitors on release cabinet, as applicable.

  7.4 Foam fire-extinguishing systems

  • .1 visually inspect all accessible components for proper condition;

  • .2 functionally test all fixed system audible alarms;

  • .3 flow test all water supply and foam pumps for proper pressure and capacity, and confirm flow at the required pressure in each section (Ensure all piping is thoroughly flushed with fresh water after service.);

  • .4 test all system cross connections to other sources of water supply for proper operation;

  • .5 verify all pump relief valves, if provided, are properly set;

  • .6 examine all filters/strainers to verify they are free of debris and contamination;

  • .7 verify all control/section valves are in the correct position;

  • .8 blow dry compressed air or nitrogen through the discharge piping or otherwise confirm the pipework and nozzles of high expansion foam systems are clear of any obstructions, debris and contamination. This may require the removal of nozzles, if applicable;

  • .9 take samples from all foam concentrates carried on board and subject them to the periodical control tests in MSC.1/Circ.1312, for low expansion foam, or MSC/Circ.670 for high expansion foam. (Note: Except for non-alcohol resistant foam, the first test need not be conducted until 3 years after being supplied to the ship.); and

  • .10 test all fuel shut-off controls connected to fire-protection systems for proper operation.

  7.5 Water mist, water spray and sprinkler systems

  • .1 verify proper operation of all water mist, water-spray and sprinkler systems using the test valves for each section;

  • .2 visually inspect all accessible components for proper condition;

  • .3 externally examine all high pressure cylinders for evidence of damage or corrosion;

  • .4 check the hydrostatic test date of all high pressure cylinders;

  • .5 functionally test all fixed system audible and visual alarms;

  • .6 flow test all pumps for proper pressure and capacity;

  • .7 test all antifreeze systems for adequate freeze protection;

  • .8 test all system cross connections to other sources of water supply for proper operation;

  • .9 verify all pump relief valves, if provided, are properly set;

  • .10 examine all filters/strainers to verify they are free of debris and contamination;

  • .11 verify all control/section valves are in the correct position;

  • .12 blow dry compressed air or nitrogen through the discharge piping of dry pipe systems, or otherwise confirm the pipework and nozzles are clear of any obstructions. This may require the removal of nozzles, if applicable;

  • .13 test emergency power supply switchover, where applicable;

  • .14 visually inspect all sprinklers focusing in areas where sprinklers are subject to aggressive atmosphere (like saunas, spas, kitchen areas) and subject to physical damage (like luggage handling areas, gyms, play rooms, etc.) so that all sprinklers are inspected within one year. Sprinklers with obvious external damage, including paint, should be replaced and not included in the number of sprinklers tested in subparagraph .17;

  • .15 check for any changes that may affect the system such as obstructions by ventilation ducts, pipes, etc.;

  • .16 test a minimum of one section in each open head water mist system by flowing water through the nozzles. The sections tested should be chosen so that all sections are tested within a five-year period;

  • .17 test automatic sprinklers and automatic water mist nozzles in accordance with the following flow chart:

    Part 1 - Basic Testing

    Part 2 - Extended testing

    • Explanatory notes to the flow chart

    • 1 Functional test is defined as a test that demonstrates the operation and flow of water from sprinkler head/nozzle.

    • 2 Type is defined as each different manufacturer model of sprinkler head/nozzle.

    • 3 Static/standby pressure is defined as the constant pressure maintained in the system at all times prior to activation.

    • 4 All testing should be carried out at static/standby pressure.

    • 5 Failure rate (RFB) is the number of sprinkler heads/nozzles to fail testing divided by test sample size multiplied by 100; and

  • .18 during basic testing, and extended testing when applicable, of automatic sprinkler heads/nozzles as outlined in subparagraph .17, water quality testing should be conducted in each corresponding piping section. Note – should a tested sprinkler fail, assessing the corresponding water quality at that time would assist in determining the cause of failure.

  7.6 Ventilation systems and fire dampers

  • .1 test all fire dampers for remote operation;

  • .2 verify galley exhaust ducts and filters are free of grease build-up; and

  • .3 test all ventilation controls interconnected with fire-protection systems for proper operation.

  • .2 check all breathing apparatus face masks and air demand valves are in serviceable condition; and

  • .3 check EEBDs according to maker's instructions.

  7.9 Fixed dry chemical powder systems

  • .1 visually inspect all accessible components for proper condition;

  • .2 verify the pressure regulators are in proper order and within calibration; and

  • .3 agitate the dry chemical powder charge with nitrogen in accordance with system manufacturer's instructions. (Note:Due to the powder's affinity for moisture, any nitrogen gas introduced for agitation must be moisture free.)

  7.10 Fixed aerosol extinguishing systems

 Verify condensed or dispersed aerosol generators have not exceeded their mandatory replacement date. Pneumatic or electric actuators should be demonstrated working, as far as practicable.

  7.11 Portable foam applicators

  • .1 verify all portable foam applicators are set to the correct proportioning ratio for the foam concentrate supplied and the equipment is in proper order;

  • .2 verify all portable containers or portable tanks containing foam concentrate remain factory sealed, and the manufacturer's recommended service life interval has not been exceeded;

  • .3 portable containers or portable tanks containing foam concentrate, excluding protein based concentrates, less than 10 years old, that remain factory sealed can normally be accepted without the periodical foam control tests required in MSC.1/Circ.1312 being carried out;

  • .4 protein based foam concentrate portable containers and portable tanks should be thoroughly checked and, if more than five years old, the foam concentrate should be subjected to the periodical foam control tests required in MSC.1/Circ.1312, or renewed; and

  • .5 the foam concentrates of any non-sealed portable containers and portable tanks, and portable containers and portable tanks where production data is not documented, should be subjected to the periodical foam control tests required in MSC.1/Circ.1312.

  7.12 Wheeled (mobile) fire extinguishers

  • .1 perform periodical inspections in accordance with the manufacturer's instructions;

  • .2 visually inspect all accessible components for proper condition;
