INSPECTION AND COMMON CHECKS-CONTINUED
Bolts, nuts, and screws
Check them for obvious looseness, missing, bent, or broken condition on equipment. If you find a bolt,
nut, or screw you think is loose, tighten it or report it to your supervisor.
Hoses
Look for wear, damage, and leaks. Ensure clamps are tight. Wet spots indicate leaks, but a stain around
a fitting or connector can also mean a leak. If a leak comes from a loose fitting or coupling, shut down the
equipment and tighten it. If something is broken or worn out, report it to your supervisor.
Leakage Definition for Unit PMCS
CAUTION
Equipment operation is allowable with Class I and II leaks. Consideration must be given
to fluid capacity in the system. When in doubt, check with your supervisor. When
operating with Class I or II leaks, frequently check leak intensity. Report Class III leaks to
your supervisor.
Class I - Leakage 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 or inspected.
Class III - Leakage of fluid great enough to form drops that fall from items being checked
or inspected.
It is necessary for you to know how fluid leakage affects the status of the equipment. The caution above
lists the types/classes of leakage an operator needs to know to determine the status of the water system.
If you spot a leak and are unsure what class the leak is, notify your supervisor or unit maintenance.
