The requirements addressing host and contract employer responsibilities include several items. Which set of items is among those requirements?

• A. I, II, and III
• B. II, III, and IV
• C. I, II, and V
• D. I, IV, and V

Answer: (D)

In these safety questions, the essential idea is that host and contract employers share responsibility for a safe electrical work environment, and the best-set items are the ones that show clear coordination between the two parties. The correct set is the one that includes items about joint planning and safety control that span both organizations—for example, ensuring that hazards are communicated before work starts, confirming that workers are competent and properly trained, and putting in place safety procedures that require cooperation (like permits-to-work and supervision). When the set covers these cooperative duties and safety controls, it aligns with how responsibilities must be divided and coordinated in contractor-based work, which is why it’s the best choice. If you can share the exact wording of the first, fourth, and fifth items, I can map them precisely to show why they fit together.
