32: Risk Acceptance Issue
Definition/Typical Issues
Were the wrong or inappropriate risk-acceptance criteria used for analyzing the maintenance needs? Was corrective maintenance assigned even though the consequences of failure are very high?
Examples
Example 1
- Corrective maintenance was assigned to a conveyor that provided raw materials to a food process. Experience indicated that failures took about 16 hours to repair. The risk acceptance criteria did not include downtime as one of the criteria used when assessing the overall risk associated with a failure.
Example 2
- The analysis team assigned predictive, event-based, and periodic maintenance activities to equipment with failures that resulted in large consequences. They assigned corrective maintenance to equipment with failures that had only low consequences. However, the risk associated with the low-consequence, high-frequency incidents was larger than that associated with some of the high-consequence, infrequent events. The risk acceptance criteria outlined in the analysis procedure incorrectly led them to believe that they were assigning the correct type of maintenance to these different types of risks.
Typical Recommendations
- Ensure that the proper level of risk acceptance is used in determining the level and type of maintenance to perform on equipment.
- Provide guidance in the analysis procedure to allow for consistent application of the risk acceptance criteria. Use specific examples.
