LEAKAGE DEFINITIONS FOR UNIT PMCS
It is necessary for you to know how fluid leakage affects the status of the equipment. Following are types/
classes of leakage an operator needs to know to be able to determine the status of the latrine. Learn these
leakage definitions; when in doubt, notify your supervisor.
Equipment operation is allowable with minor leakages (Class I or Class II). Of course,
consideration must be given to fluid capacity in the item/system being checked/inspected.
When in doubt notify your supervisor. When operating with Class I or II leaks, continue to
check fluid levels as required in your PMCS. Class III leaks should be reported immediately
to your supervisor.
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
item being checked/ inspected.
CLASS III - Leakage of fluid great enough to form drops that fall from item being checked/ inspected.
