6.0 QUALITY ASSURANCE REQUIREMENTS: None additional

7.0 STATEMENT OF WORK REQUIRED

7.1 Inspect, clean, and test the fixed Halon and CO2 fire extinguishing systems identified in section 3.0 using References 2.1.1 through 2.1.7 and Enclosure 2.2.1 through 2.2.5 as guidance. Accomplish inspection, cleaning, and testing in accordance with IMO, SOLAS, and the Manufacturer’s requirements.

7.2 Coordinate with ship’s force to have the associated equipment and system locked and/or tagged out per ship’s lock out/tag out policy to prevent accidental discharge. When the maintenance is complete, coordinate with ship’s force to have associated equipment unlocked and/or tagged in per ship’s lock out/tag out policy.

7.2.1 Tag-out the fixed Halon and CO2 systems and controls to prevent accidental discharge.

7.3 Conduct an annual inspection of all fixed Halon and CO2 systems and complete Enclosures 2.2.1 through 2.2.4.

Inspect all piping, controls, actuators, remote pulls, valves, time delays, pressure switches, sirens and alarms, extinguishing agent, expelling means and physical condition to verify the system is in good order.

7.3.1 Verify all markings, operating instructions and warning placards are in place, unobstructed and marked legible using Enclosure 2.2.5, 46 CFR §97.37 and §95.15 as guidance. Ensure operating instructions are located in a conspicuous place at or near pull boxes, stop valve controls and in the cylinder storage room. On systems where the cylinders are within the protected space, ensure the instructions include a schematic diagram of the system and instructions detailing alternate methods of discharging the system should the manual release or stop valve fail to operate.

7.3.2 Conduct an external visual examination of all cylinders, including CO2 cylinder for hose reels identified in paragraphs 3.2.2.b through d and complete Enclosures 2.2.1 through 2.2.4. Identify any obvious physical damage, dents, bulging, and corrosion. Verify each cylinder is clearly marked and record all data including name of manufacturer, year of manufacturer, serial number and size and determine if a hydrostatic test is due.

7.3.3 Include in estimate the weighing of SIX (6) 75# CO2 cylinders, FIFETEEN (15) 125# Halon cylinders, and EIGHT (8) 5# CO2 cylinders.

7.3.4 Include in estimate the hydrostatic testing of two (2) 50# CO2 cylinders and ten (10) 125# Halon cylinder.

7.3.5 Verify containers/cylinders fitted with a pressure gauge are in the proper range and the installation is free from leakage.

7.3.6 Verify and record the weight of charge in each cylinder. Subtract the tare weight (empty container) from the measured gross weight to determine the net weight of the extinguishing agent in the cylinder. For Halon systems see below. The measured weights or liquid levels must be compared with the recommended fill levels and previous readings.

46 CFR §147.65 (b)(1) allows one of three methods:

(1) The cylinders may be removed from the mounting racks and weighed.

(2) The contents of cylinders fitted with integral floating dipstick liquid level indicators may be measured with the dipstick indicator.

(3) With approval of the cognizant USCG Officer in Charge, Marine Inspection (OCMI), liquid level indication measures such as ultrasonic/audio gauging or radioisotope gauging may be used, provided that all of the following conditions are met:

(i) Measurement equipment is calibrated for the cylinder wall thickness and Halon liquid.

(ii) Calibration is verified by weighing the cylinders that indicate the lowest levels of Halon in each release group, but in no case less than 10 percent of the inspected cylinders in each release group.

(iii) The acceptable liquid level is identified by the original system installer or coincides with all other cylinder liquid levels of the same release group.

(iv) Measurements are made by personnel skilled in ultrasonic/audio gauging or radioisotope gauging techniques.

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.

HALON CYLINDER TWO YEAR TESTING AND INSPECTIONS: All Halon cylinders and pilot cylinders should be weighed or have their contents verified by other reliable means to confirm that the available change in each is above 95 percent of the nominal charge. Cylinders containing less than 95 percent of the nominal charge should be refilled.

HALON CYLINDER TEN YEAR TESTING AND INSPECTIONS: Perform a hydrostatic test and internal examination of 10 percent of the system’s extinguishing agent and pilot cylinders. If one or more cylinders fail, a total of 50 percent of the onboard cylinders should be tested. If further cylinders fail, all cylinders should be tested. If permitted by the Administration, visual inspection and NDT (non-destructive testing) of Halon cylinders may be performed in lieu of hydrostatic testing.

CO2 CYLINDER TWO YEAR TESTING AND INSPECTIONS: All high pressure CO2 cylinders and pilot cylinders should be weighed or have their contents verified by other reliable means to confirm that the available change in each is above 90% percent of the nominal charge. Cylinders containing less than 90% percent of the nominal charge should be refilled. The liquid level of low pressure storage tanks should be checked to verify that the required amount of carbon dioxide to protect the largest hazard is available.

CO2 CYLINDER TEN YEAR TESTING AND INSPECTIONS: The hydrostatic test date of all storage cylinders should be checked. High pressure cylinders should be subjected to periodical tests at intervals not exceeding 10 years. At the 10-year inspection, at least 10% of the total number provided should be subjected to an internal inspection and hydrostatic test. If one or more cylinders fail, a total of 50% of the onboard cylinders should be tested. If further cylinders fail, all cylinders should be tested. Refer to standard ISO 6406 – Periodic inspection and testing of seamless steel gas cylinders.

ENCLOSURE 2.2.5 PLACARD AND MARKINGS

and §95.15-10 Each control valve to branch lines of all fire extinguishing systems shall be plainly and permanently marked indicating the spaces served.

CO2

(a) Spaces storing carbon dioxide “CARBON DIOXIDE GAS CAN CAUSE INJURY OR DEATH. VENTILATE THE AREA BEFORE ENTERING. A HIGH CONCENTRATION CAN OCCUR IN THIS AREA AND CAN CAUSE SUFFOCATION.”.

(b) Spaces protected by carbon dioxide - “CARBON DIOXIDE GAS CAN CAUSE INJURY OR DEATH. WHEN ALARM OPERATES OR WINTERGREEN SCENT IS DETECTED, DO NOT ENTER UNTIL VENTILATED. LOCK OUT SYSTEM WHEN SERVICING.” The reference to wintergreen scent may be omitted for carbon dioxide systems not required to have odorizing units and not equipped with such units.

(c) Spaces into which carbon dioxide might migrate “CARBON DIOXIDE GAS CAN CAUSE INJURY OR DEATH. DISCHARGE INTO NEARBY SPACE CAN COLLECT HERE. WHEN ALARM OPERATES OR WINTERGREEN SCENT IS DETECTED VACATE IMMEDIATELY.” The reference to wintergreen scent may be omitted for carbon dioxide systems not required to have odorizing units and not equipped with such units

Odorizing units

Each carbon dioxide extinguishing system installed or altered after July 9, 2013, must have an approved odorizing unit to produce the scent of wintergreen, the detection of which will serve as an indication that carbon dioxide gas is present in a protected area and any other area into which the carbon dioxide may migrate.
