Which of the following is NOT a valid leakage classification?

• A. Class I
• B. Class II
• C. Class III
• D. Class IV

Answer: (D)

Leakage classifications give a standardized way to describe how much fluid escapes and how to respond. In this system, only three levels are defined, with each level having specific guidance for containment and actions. There is no defined fourth level, so a designation for a fourth class doesn’t fit the established categories. That’s why the option describing a fourth class is not a valid leakage classification. The three recognized levels are used to assess and guide the appropriate response.
