Which step is NOT generally taken when gas-freeing a tank?
AI Explanation
The correct answer is D) Application of degreasing solvents.
When gas-freeing a tank, the typical steps do not involve the application of degreasing solvents. The proper steps are: 1) Removal of corrosion products and sludge, 2) Fresh air ventilation to displace any hazardous vapors, and 3) Washing the tank interior with sea water to remove any remaining residues. Degreasing solvents are generally not used as part of the gas-freeing process, as they can introduce additional fire and explosion hazards. The other answer choices (A, B, and C) describe the standard gas-freeing procedures, while the use of degreasing solvents is not a typical step in this process.
