Class I - Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
Class II - Leakage of fluid great enough to form drops, but not enough to cause drops to drip from the
item being checked/inspected.
Class III - Leakage of fluid great enough to form drops that fall from the item being
Equipment operation is allowable with minor leakages (Class I or II). However, the fluid level
or operating pressure of the item being checked/inspected must be considered. When in
doubt, notify the shift leader or bargemaster. When operating with Class I or Class II leaks,
continue to check fluid levels as required by PMCS and operating Instructions.
The following fuel and hazardous material leakage procedures apply for any fuel, chemical, or bilge
Class 1, 11 or III leaks or seepage occurring In a fuel, chemical, or bilge container, tank, line,
piping, or valve can cause fire or health hazards.
If any leaks or see page from a fuel, chemical, or bilge container, tank, or fluid line is detected, it must be
immediately reported to the shift leader or bargemaster for corrective action.
To prevent combustible or toxic fumes from collecting or contaminated material from spilling, exercise
extreme caution after detecting leaks or seepage of flammable or hazardous material.
Continuous operation. When equipment must be kept in continuous operation for extended periods of time,
check and service only those items that can be checked and serviced without disturbing operations. Perform
complete checks and services when the equipment can be shut down.
Maintenance log. Always record the time and date of PMCS, any deficiencies noted, and corrective action taken
in the PMCS log book.
C-2 Major components. The chlorination system consists of a priming brine tank and holding tank, chlorine generation
and recirculation unit, metering pump control unit, acid tank, various pumps, flowmeters, pressure gauges, and valves.
In addition, there are associated indicator lights, LED displays, fluid lines, piping, sensors, switches, and electrical
circuitry. Major components of the chlorination system, their basic functions, and their location on the barge are listed in
C-3 Chlorination system description. The chlorination system generates a strong solution of sodium hypochlorite
(commonly called chlorine) for treating water produced by the Reverse Osmosis Water Purification Units (ROWPU's).
Adding this solution to the water makes it safe for human consumption. A metering pump adds this solution, upon
demand, to water processed by the ROWPU system just before the water enters the four drinking water storage tanks.
The system generates and maintains a 5000 to 6000 parts per million (ppm) solution of chlorine and then meters this
solution into product water from the ROWPU system to obtain a chlorine concentration of 5 to 7 ppm in the drinking
