Abnormal Operating Procedures are the documents that lay out how operators should respond when things start to go off normal. They provide structured, step-by-step actions for diagnosing what’s not right, implementing corrective actions, and monitoring critical parameters as the situation evolves. The goal is to bring the plant back to safe operation or to transition to a more protective mode if needed, without jumping straight to an emergency.

Emergency Operating Procedures handle more severe, immediate situations that threaten safety and require rapid protective actions to stabilize the plant. Alarm Response Procedures focus on how to respond to alarms, which is part of the process but not the full set of actions for an abnormal condition. Normal Operating Procedures cover routine, everyday operations under normal conditions.
