During an air or surface nuclear attack, what is the first thing all topside personnel should do?

• A. Seek immediate shelter
• B. Evacuate to sea
• C. Don protective gear
• D. Continue operations

Answer: (A)

The immediate priority in a nuclear attack is to seek shelter. Getting to a protected space right away dramatically reduces exposure to the blast overpressure, heat, flying debris, and prompt radiation. PPE takes time to don and isn’t effective enough against the initial hazards, so sheltering first is the safest move. Evacuating to sea would expose you to open hazards and radiation with less protection, and continuing operations would ignore the urgent danger. Once shelter is secured, you can follow procedures to don protective gear and carry on with proper decontamination and readiness as directed.
