Impair quality of life.
Cause environmental problems.
Require a long lead-time for replacement.
2.2.2 Systems Inventory. A systems inventory shows all vents, pipes, anodes,
rectifiers, valves, inspection access, motors, traps, filters, and other components for a
single system. Within each system a separate sublist may indicate components requiring
preventive maintenance and those that are repaired by replacement. Each system re-
quires inspection and is the responsibility of both Control Inspectors and Preventive
Maintenance Inspectors depending on the type inspection performed.
2.2.3 Preventive Maintenance Inspection (PMI) Inventory. A PMI inventory is
a listing of items of dynamic equipment requiring periodic lubrication, adjustment
and/or inspection. PMI of equipment with an assigned operator is generally part of the
operator's SOPS, especially if failure would have serious consequences. If the operator
does not have time or training to perform the work, it should be included in the PMI
program. PM Inspection is particularly applicable to unattended:
Water supply, treatment, and distribution systems.
Sewage collection and treatment systems.
Fuel storage and handling facilities.
Compressed air and industrial gas generating and distribution systems.
Electric generating and distribution systems.
Appurtenants to cathodic protection equipment systems.
Heating, ventilating, refrigeration, air conditioning equipment and
Bakery, food preparation and service, and dish washing equipment.
Public Works shop equipment.
2.2.4 Replacement Items Inventory. Small items such as fractional horsepower
motors, water coolers, self-lubricating fans, window unit air conditioners, automatic
door closers and other sealed units do not normally require preventive maintenance un-
less critical to a mission essential operation. These items are replaced when they break
down. Control Inspection of systems and user complaints (numerous E/S calls) also
identify the need to replace items. An inventory of such items, with replacement dates,
including stock or availability data should be maintained.
