Which step is NOT generally taken when gas-freeing a tank?
AI Explanation
The correct answer is A) Application of degreasing solvents.
When gas-freeing a tank, the general steps do not include the application of degreasing solvents. The typical steps are: removal of corrosion products and sludge, fresh air ventilation to remove flammable vapors, and washing the tank interior with sea water to remove any remaining residues. Degreasing solvents are not used in this process, as they could introduce additional flammable hazards. The other options (B, C, and D) are all standard practices for properly gas-freeing a tank, but the application of degreasing solvents is not.
