36: Implementation Issue
Definition/Typical Issues
Was the periodic maintenance activity incorrectly performed? Was there a failure to service all required components? Were some items included on the schedule that were never performed?
Was there a failure to perform periodic maintenance at the specified (i.e., scheduled) frequency? Were some periodic maintenance tasks being skipped?
Note 1: This node addresses how often the periodic maintenance is actually done. Frequency Specification Issue (#35) addresses how often the task was supposed to be performed.
Examples
Example 1
- An inexperienced mechanic incorrectly installed a pump seal during periodic maintenance, which subsequently leaked. He inserted one of the rubber seals backwards. The procedure provided no guidance other than to "install the rubber seals."
Example 2
- Periodic maintenance (a calibration) was being performed on a scale every 3 months. The required calibration frequency had been changed to once per month about 2 years ago after the company was fined for shipping overloaded trucks. However, the instrumentation technicians still performed the calibration only once every 3 months.
Example 3
- A pump failed soon after installation, far short of the life expectancy of the pump. Investigation revealed that the pump had been stored in the warehouse for a long time. During the storage, no periodic maintenance, such as cleaning and lubrication, had been performed as specified in the manufacturer's instructions for storage.
Example 4
- An electrician was performing a maintenance check on a pressure instrument. During performance of the check, a high pressure signal was simulated in the instrument loop. Because the loop was not properly isolated, it resulted in a pressure relief valve lifting and a release to the environment.
Typical Recommendations
- Review maintenance procedures to ensure that they provide adequate guidance based on the experience level of personnel.
- Provide training for personnel on periodic maintenance techniques.
- Review the periodic maintenance schedule and completed work requests to ensure that all required activities are being performed.
- Perform post-maintenance testing to ensure that the maintenance is properly performed.
- Ensure that periodic maintenance tasks are being performed as specified.
- Perform maintenance activities in accordance with the equipment reliability program.
- Include steps in repair procedures to ensure that equipment is fit for service when it is turned over to the production team.
