Show answer & explanationAnswer & explanation
Correct answer: D. Implementing a work/warm-up schedule with frequent breaks in heated shelters.
Administrative controls involve changing work practices. Implementing a work/warm-up schedule with frequent breaks in heated shelters is a classic administrative control that directly limits exposure duration and allows for body temperature recovery.
Why the other options are wrong
- A. Enclosing and heating machinery cabs is an engineering control.
- B. Offering hot beverages and snacks is a supportive measure but not a primary administrative control for managing exposure time.
- C. Providing insulated gloves and hats is personal protective equipment (PPE).
