What procedure helps ensure operation managers and employees know how to react in emergencies?

The procedure that helps ensure operation managers and employees know how to react in emergencies is emergency response procedures. These procedures are designed to provide clear and detailed guidelines on how to handle various types of emergencies, such as chemical spills, fire, or extreme weather events. They define specific actions to take, roles and responsibilities during an emergency, communication protocols, and evacuation routes if necessary.

Having these procedures in place is crucial because they prepare employees and management to respond quickly and effectively, minimizing risks to safety and health. Training on emergency response procedures can also empower staff to act confidently in high-pressure situations, which can be vital for ensuring everyone's safety and maintaining operational continuity.

The other options address different aspects of workplace safety but do not focus specifically on emergency response preparation. Maintenance protocols primarily deal with equipment upkeep, safety drills involve practicing response to emergencies, and standard operating procedures cover general operational tasks but do not specifically encompass emergency situations.
