Preventive Maintenance
Section 8.1
Preventive Maintenance (PM) Introduction
8.1.1 Why Do Preventive Maintenance?
A preventive maintenance program monitors the equipment and guarantees the best results from
good equipment performance.
Ensuring quality assurance includes:
• strict installation procedures (parts are designed to be installed a certain way)
• a pre-shipment Radiation Survey which ensures compliance with the United States’ Radiation
Control for Health and Safety Act and the Canadian RED Regulations C.R.C.
• itemized torque settings that prevent damage to items that come loose and avoid deformations
caused through over tightening
• software systems which run under a designed set of tolerances
• regularly scheduled preventive maintenance.
8.1.2 Record Keeping
Accurate record keeping is a vital part of preventive maintenance and quality control. Maintaining
accurate records which includes a well maintained history of the unit assists Service Technicians
with their system diagnosis should problems occur. It also makes the scheduled maintenance of the
system easier.
System records are maintained as follows:
• A calibration history is stored electronically in the systems D:\calib directory
• A hardcopy Device History Record folder is maintained for each system. It contains:
- results of each Radiation Survey performed on the system
- a history of all service calls and replacement parts, Preventive Maintenance Performance
Checklists, and tracks updates to both the hardware and software.
8.1.3 Scheduling Preventive Maintenance
Performing periodic minor maintenance lengthens the time needed between major maintenance.
Performing periodic major maintenance lengthens the time between the occurrence of any serious
problems. Scheduling preventive maintenance gives Service Technicians:
• the opportunity to inspect and verify that the system is running under normal parameters
