e. Hoses and Fluid Lines: Look for wear, damage and leaks. Check for loose clamps and fittings. Wet spots
show leaks, of course, but a stain around a fitting or connector can mean a leak. If a leak comes from a loose fitting or
connector, tighten it. If something is broken or worn out, report it to Organizational Maintenance.
2. It is necessary for you to know the definitions of the types/classes of leakage and how it determines the status of
your equipment.
a. Leakage definitions are as follows:
CLASS I
Seepage of fluid (as indicated by wetness of 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 drips that fall from the item being checked/inspected.
CAUTION
Equipment operation is allowable with minor leakage (Class I or II). Of course, consideration
must be given to the fluid capacity in the item/system being checked/inspected. When operating
with Class I or II leaks, continue to check fluid levels as required in your PMICS. Class III leaks
should be reported to your supervisor or to Organizational Maintenance.
b. Learn and remember the definitions of Class I, II and III leaks - IHEN
