39: Event Specification Issue
Definition/Typical Issues
Was an incorrect triggering event specified for the event-based maintenance? Was no triggering event specified for the event-based maintenance?
Examples
Example 1
- Product barrels were cleaned as they were returned from customers. However, some product was contaminated when it was placed in the barrels. Dust would accumulate in barrels that were not used for extended periods and contaminate the product. Cleaning was switched to shortly before use instead of when the barrels were returned from the customers.
Example 2
- Tubes in a heat exchanger were failing prematurely. The tubes were rinsed prior to starting a new batch, but they were not cleaned at the completion of each batch. As a result, the material remaining in the tubes between batches caused the tubes to corrode.
Typical Recommendations
- Ensure that triggering events for event-based maintenance are appropriate for the component.
- Review repair records to determine whether the triggering events or triggering levels need to be modified.
