What is the primary action to take when there is a loss of electrical power on board?

When there is a loss of electrical power on board, the primary action is to start emergency generators. This step is crucial because maintaining power is essential for navigation, communication, and the operation of safety systems aboard the vessel. Emergency generators are specifically designed to provide power in situations where regular power sources are lost, ensuring that critical systems remain operational during an outage.

Initiating the emergency generators promptly can help stabilize the situation and prevent further complications, such as the failure of essential systems or the loss of situational awareness. While other actions, like notifying the Command Duty Officer (CDO) or logging the incident, are important, they typically follow the immediate response of restoring power. The focus should always be on addressing the loss of electricity to ensure the safety of the ship and its crew.
