When water washing epoxy-coated cargo tanks, the temperature and pressure of the wash water should generally not exceed _______________.

AI Explanation
The correct answer is D) 120°F - 120 psi. The temperature and pressure of the wash water used for cleaning epoxy-coated cargo tanks should generally not exceed 120°F and 120 psi. This is to prevent damage to the epoxy coating, which can be sensitive to higher temperatures and pressures. Exceeding these limits could cause the coating to blister, crack, or delaminate, compromising the tank's integrity. The other options are incorrect because they specify either higher temperatures (212°F or 180°F) or higher pressures (940 psi or 180 psi), which would be too harsh for the epoxy coating and could lead to its deterioration.
