OPERATOR'S PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
Preventive Maintenance Checks and Services (PMCS) involves systematic caring, inspection, and servicing of equipment to
keep it in good condition and prevent breakdowns. WP 0011 PMCS organizes the operator's PMCS tasks in chronological
sequence. Service intervals are divided into categories: Before Operation; During Operation; After Operation; and various
other checks and services to be performed at prescribed hourly intervals. As the Drum operator, you should:
Perform your PMCS as scheduled. Always do your PMCS in the same order, so it gets to be a habit.
Do your BEFORE PMCS prior to the Drum leaving its staging/service area or performing its intended mission.
Keep in mind the WARNINGS and CAUTIONS.
Do your DURING PMCS during Drum operation. Leaks can be spotted only during operation. Keep in mind
the WARNINGS and CAUTIONS.
Do your AFTER PMCS as soon as possible after the Drum has been taken out of its mission mode or returned
to its containment area. Keep in mind the WARNINGS and CAUTIONS.
If your equipment fails to operate, perform the operator troubleshooting procedures presented in this manual.
Report unresolved maintenance problems to unit maintenance personnel.
It is necessary for you to know how fluid leakage affects the status of the Drum. Wetness around seals, gaskets, fittings or
connections indicates leakage. A stain also indicates leakage. If a fitting or connector is loose, tighten it. If it is broken or
defective, report it. Following are types/classes of leakage you need to know to be able to determine the status of the Drum.
Learn these leakage definitions and remember - when in doubt, notify your supervisor.
Equipment operation is allowed with minor leakages (Class I or II).
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 the 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 or inspected.
Class III - Leakage of fluid great enough to form drops that fall from item being checked or inspected.
