leakage an operator must know to determine whether the trailer is mission capable. Learn these leakage
definitions. When in doubt, notify 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 great 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.
CAUTION
Equipment operation is allowable with minor leakage (Class I or II). O f
