MAINTENCE PRIORITY RATING
1.6 Purpose
To provide maintenance department, with an indication of the relative importance and hierarchy,
of planned and unplanned works.
1.7 Policy
Maintenance priority rating will be applied to the following documents:
Work requests
Work Orders
1.8 Priority Levels
The following logic will be followed when assigning priorities to work requests:
Emergence (P0): P0 rating (emergency) will apply to any identified abnormal or faulty
conditions hazardous to life and equipment or loss of energy flow. Upon validation the executor
shall repair immediately, paper work to follow later. These works can override the jobs on the
daily schedule.
Urgent (P1): P1 rating (urgent) will apply to any identified faulty or abnormal condition where
serious safety hazard exists or distribution of energy will be interrupted unless the defect is
repaired within 7 days. Upon validation the executor can carry out a repair job within 7 days.
These works can override the jobs on the weekly schedule.
NORMAL (P2): P2 rating (Normal) will apply to any identified faulty or abnormal condition
which is not hazardous to life and equipment or will not result to interruption of power if not
corrected within 14 days. Upon validation such works should be planned and executed within the
next 14 days.
These works can interrupt selected jobs on the monthly schedule.
8/22/2019 MMS Manual Ver3

WORK TYPES
1.9 Purpose
To categorise all works in PEMS so as to be able to identify the various types of jobs that are
being executed
1.10 Policy
All works that are being carried out in the system need to be classified according to work type.
This also facilitates easy preparation of reports according to various work categories.
1.11 Activity Description
The under listed are the types of works encountered in the execution of jobs under MMS. The
selection of these work types shall apply in both the Request and Work Order modules.
1.11.1 Planned Corrective Work
This shall apply to works that are to be executed from the 52 week plan and those jobs arising
from requests with priorities P2 and P3 ie non emergency or urgent jobs.
1.11.2 Routine Maintenance
This shall apply to works that are to be executed in connection with works that are routinely
done on a regular basis such as inspection, cleaning, oiling etc. This are planned jobs with
priority P2 or P3.
1.11.3 Predictive Maintenance
Predictive Maintenance or Condition Based Maintenance attempts to evaluate the condition of
equipment by performing periodic or continuous (online) equipment condition monitoring. The
ultimate goal of Predictive Maintenance is to perform maintenance at a scheduled point in time
when the maintenance activity is most cost-effective and before the equipment loses performance
within a threshold. This is in contrast to time- and/or operation count-based maintenance, where
8/22/2019 MMS Manual Ver3
11/35
MAINTENANCE MANAGEMENT
MANUAL
ZESCO
a piece of equipment gets maintained whether it needs it or not. Predictive maintenance will
always have planned or scheduled start date and time hence it is planned work.
1.11.4 Project or Modification Work
This shall apply to works that are to be executed in connection with project works or overhauls
being carried out. This are planned jobs with priority P2 or P3.
1.11.5 Emergency Unplanned Work
This shall apply to works that are to be executed under emergency and urgent situations. This
arises when there is loss of supply and where safety of life and equipment is threatened.
Unplanned emergency works shall be executed on priority P0 or P1 and as such these jobs take
priority over planned jobs.

scheduling or maintenance resources. The sources of backlog work would include all identified
corrective work arising from inspections or works on the master weekly reschedule that has not
been executed for various reasons such as lack of materials, maintenance windows etc.The
purpose of a maintenance backlog is to provide an effective means of identifying and monitoring
outstanding maintenance works.
1.22 Policy
All maintenance work orders that cannot be scheduled due to lack of maintenance resources shall
be posted to the backlog inventory. This shall not include unfulfilled recurring planned works
on the predetermined preventive maintenance schedule. Should experience prove otherwise, this
will be changed. Using PEMS to keep track of the maintenance backlog implies that the back
log will consist of work orders that are in the requested or on hold status only.

faults men. However when the magnitude of these faults are too complex to be handled by faults
men, a notification is made to the planning office by way of request or IMS-PEMS inter phasefor the works to be managed through the planning office.
1.28 Policy
All materials drawn for the purpose of resolving incidences and labour utilised need to be
properly accounted for in PEMS. Materials for faults will have to be drawn from stores in
advance such that materials for faults are available when needed.
1.29 Activity Description
A work order for the management of faults shall be raised at the beginning of each month with
the estimated material requirements requisitioned in this works order. The work description of
this works order shall be Faults Management. The materials will be kept in a secure place
where it will only be accessed by the Faults Coordinator or any other person assigned by the
Regional Manager. Once the faults are cleared, the information is updated in the work order for
materials and labour used including a brief account of incidence in the work order tasks. This
information shall be updated in the work order by the person in charge of operations such as the
operations engineer, technologist etc on a daily basis.
If for some reason further requisitions of material and tasks are required, supplementary child
work orders can be raised to support extra information and requisitioning. At the end of the
month all unused materials are returned and then re- issued to the succeeding work order in the
following month. The work orders should not overrun the months. This is to say that all work
orders raised in the particular month should be closed within that month for ease of report
preparations and monthly accountabilities.
