What must be done to clear a P1 or P2 alarm?

To address a P1 or P2 alarm properly, it is crucial to follow a systematic procedure that ensures both safety and effective resolution of the alarm condition. This approach often involves notifying the Control Room Personnel (PDO), investigating the underlying issue causing the alarm, and then taking the necessary steps to reset the alarm.

By notifying PDO, you ensure that those responsible for monitoring system operations are aware of the situation, enabling them to assess safety implications and take additional actions if required. Investigating the issue allows you to determine the cause of the alarm—whether it's a minor operational glitch or indicates a more serious concern that could impact equipment performance or safety.

After completing the investigation and ensuring the area and equipment are safe to operate, resetting the alarm confirms to the system that the issue has been addressed, thus returning it to normal operational status. This thorough process helps maintain operational integrity and safety standards.

Other approaches, such as attempting to reset the alarm without notifying anyone or waiting for it to clear on its own, do not address the root cause of the alarm and could result in further complications. Disconnecting all power to the equipment could pose significant safety hazards and should only be done in specific scenarios following established protocols.
