What is the first action when a rice-cooker bomb is found on the quarterdeck?

Evacuating the area is the most critical first action when a rice-cooker bomb, or any suspicious device, is discovered. The priority in such a situation is to ensure the safety of all personnel present. By moving away from the device, you minimize the risk of injury from a potential explosion or detonation.

Once a safe distance is established, it allows for further actions to be taken, such as securing the area and calling in local authorities who are trained to handle explosives. This immediate evacuation helps to ensure that others are not exposed to danger and provides a clear space for emergency responders to manage the situation effectively.

The other options, such as opening the device or checking for injuries, involve direct contact with a potential threat and could endanger lives. Only after evacuation and securing the area should authorities be involved to assess the situation and handle the device. This response outlines the proper protocol in emergency situations involving unexploded ordnance or suspicious devices.
