Highlight your attention to detail and your ability to communicate technical information clearly and concisely. Discuss any protocols you follow for logging incidents, including the importance of timeliness and accuracy.

Example: “I rely on a combination of digital tools and standardized forms to ensure thorough and accurate documentation. Using a Computerized Maintenance Management System (CMMS) is my go-to method. It allows me to log each maintenance activity, including the date, time, parts used, and any issues encountered. This ensures that all information is centralized and easily accessible for future reference.

For incidents, I follow a standardized reporting protocol that includes filling out detailed incident reports immediately after the event. These reports are comprehensive, covering the root cause analysis, corrective actions taken, and preventive measures for the future. I also make sure to communicate these reports to the relevant stakeholders, including my supervisors and the safety team, to ensure everyone is informed and appropriate steps can be taken to mitigate future risks. This dual approach of using digital tools and standardized forms helps maintain a high level of accuracy and accountability.”
