When a worker requires a safety harness for entry from the top, how should the harness function?

When a worker is required to use a safety harness for entry from the top, the primary function of the harness is to maintain the worker in a vertical position. This is crucial because it helps to prevent falls and ensures that the worker remains safely suspended in the event of a slip or loss of footing. By keeping the worker vertical, the harness can effectively distribute the forces experienced during a fall over the body, reducing the risk of injury.

Maintaining a vertical position is especially important in applications where workers are operating from heights or in potentially hazardous environments, such as when entering confined spaces from above. This vertical alignment not only aids in fall protection but also helps in easier retrieval or rescue procedures if needed.

While allowing for full movement and maintaining a seated position may have their specific applications, the primary design and function of a safety harness in this scenario is to ensure that the worker stays vertically oriented to maximize safety and protection against falls. Features such as connection to the ground serve different purposes and are not the main focus of the harness's primary function.
