If these areas are greater than 20% of the tank s surface area, what action should be taken? a. The areas should be washed and the wall washings included with those from the rest of the tank b. The areas should be noted on the inspection report but should not be washed c. The areas should be washed and the wall washings from these areas kept in a separate bottle d. The areas can be ignored 19. 4.77 Why should you never break blisters in a tank coating and never disturb piles of debris on a tank floor when performing a tank entry inspection? a. The tank atmosphere may be adversely affected b. The Inspector may come into contact with potentially dangerous, unknown material c.

By use of trim corrections b. By applying the wedge formula c. By using an average of the innage measurements. d. By using the innage at the official gauge point 22. 4.49 In what circumstances will a wedge condition exist? a. If liquid covers the bottom of the tank. b.
