Final answer:
If a tool listed in the MRC cannot be found, it is important to notify the supervisor.
Step-by-step explanation:
d. Notify the supervisor.
In situations where a required tool is missing, it is essential to inform the supervisor promptly. This ensures that the supervisor can assess the situation, determine the feasibility of using a substitute tool (option c) or provide guidance on how to proceed. Communication with the supervisor is crucial to maintaining safety, compliance, and the integrity of maintenance procedures. Skipping the task (option a) may compromise the maintenance process and lead to operational risks, while requesting a new tool (option b) might take time, and using a substitute tool should be done under the guidance of the supervisor to ensure it is suitable for the task at hand. The supervisor can then take appropriate action, such as replacing the missing tool, rescheduling the task, or providing an alternative solution based on the specific circumstances.
