Question 1 of 27070

If emergency welding repairs must be made to the upper area of a fuel tank, the tank and/or adjacent compartments may need to be _______.

🔍 Key Concepts

• Hot work safety on or near fuel tanks • Meaning of gas freeing vs inerting a tank • How water filling a tank affects flammable vapors and explosion risk

💭 Think About

• Think about what the main danger is when welding on a fuel tank and what condition inside the tank makes welding safer. • Are all three methods always required, or are they options that might be used depending on the situation? • Which choice best reflects that different tanks and situations may call for different protective measures?

✅ Before You Answer

• Verify how a tank can be made safe for hot work (no flammable mixture inside). • Consider whether gas freeing and inerting are two different methods to achieve a safe atmosphere. • Check if water filling can be used as an additional safety measure and if the wording "as necessary" in one option is important.
