Which hoisting option is prohibited under OSHA 1926.1431?

The correct answer pertains to the prohibition of hoist free fall under OSHA 1926.1431. This regulation emphasizes safety and operational guidelines to prevent accidents and injuries in the construction industry. Hoist free fall refers to an uncontrolled descent of the load, where it falls freely without any applied force or control mechanism to slow or stop the descent. This presents significant hazards, including the risk of injury to workers, damage to property, and the potential for severe accidents if a load unexpectedly drops.

By prohibiting hoist free fall, OSHA aims to ensure that all lifting operations maintain control over the load throughout its entire movement, from lift-off to landing. Controlled lowering methods, such as utilizing braking systems and devices designed to manage load weight and velocity, are mandated to enhance safety and efficiency in hoisting tasks.

Other options, such as controlled descent, chain hoists, and electric winches, are permissible under certain conditions as they can be designed and operated in a way that aligns with safety standards, thereby reducing risks associated with lifting operations. These alternatives incorporate mechanisms that allow for the safe handling and movement of loads without the hazards produced by free fall.
