💭 Think About

• Which person listed in the choices has specific training and authority to certify that a tank is safe for hot work? • Think about what must be checked inside a fuel tank before welding (e.g., vapors, oxygen levels). Who is legally recognized to make that determination? • Are shipboard officers normally allowed to declare a fuel tank gas-free for welding in port, or is an outside specialist required?

✅ Before You Answer

• Verify who is mentioned in 46 CFR Subchapter D or I regarding hot work on fuel tanks in port • Check which role is formally recognized by U.S. Coast Guard and NFPA standards to issue a gas-free certificate • Confirm that the person must have special certification, not just rank or management authority on board
