34: Scope Issue
Definition/Typical Issues
Was the scope of the periodic maintenance activity inappropriate (i.e., too broad or too narrow)?
Examples
Example 1
- Periodic maintenance was being performed on a furnace every week to prevent a buildup of powdered material. However, only the main chamber was being cleaned. Other portions of the furnace were not being cleaned and, as a result, the performance of the furnace degraded over time.
Example 2
- Periodic maintenance procedures require heavy pieces of rotating equipment that are not in operation to be rotated to prevent the shafts from warping. Equipment that is shut down is scheduled to be rotated once per week. However, equipment in the warehouse is not covered by the procedures. As a result, some heavy rotors failed after installation.
Typical Recommendations
- Ensure that the scope of periodic maintenance activities covers all portions of the equipment that need repair or service.
- Ensure that all of the components requiring periodic maintenance are covered by the procedures.
- Identify emergency response equipment, including required inspections and tests, and establish a system to ensure that equipment is properly maintained and tested.
