Which set of category numbers is NOT identified as part of the precautions for personnel activities?

• A. I, II, III, IV, VII, VIII, and IX
• B. V, VI, and X
• C. I, II, III
• D. VII, VIII, IX

Answer: (B)

The main idea is to know which category numbers are defined as precautions for personnel activities. The standard specifies a particular set of categories that apply directly to worker safety during tasks. The question asks which set does not appear in that personnel-precautions list. The correct choice is the one that contains category numbers not identified as part of those personnel precautions, meaning it doesn’t match the group the standard uses for worker safety during activities. The other options align with the defined personnel-precautions categories, so they are not the correct pick. In short, this choice is correct because it lists category numbers that the standard does not associate with precautions for personnel activities.
