Which device is primarily used for lifting personnel safely?

The device that is primarily used for lifting personnel safely is the personnel basket. This equipment is specifically designed to transport workers to elevated locations while ensuring their safety. Personnel baskets are engineered with safety features such as guardrails, safety harness attachment points, and often have specific load ratings. They provide a secure environment for workers, minimizing the risk of falls and accidents during aerial work.

The other options serve different purposes and are not intended for safely lifting personnel. Hoists are primarily used for lifting heavy materials or equipment rather than people. Pallet jacks are designed for moving pallets and heavy loads across flat surfaces, while winches are used for pulling or lifting objects but do not typically provide a safe environment for personnel transport. Therefore, the personnel basket is the correct answer as it meets the safety requirements for lifting individuals.
