Which hand position is appropriate for indicating a stop signal?

The appropriate hand position for indicating a stop signal is achieved by raising one arm high with the palm facing outwards. This gesture is clear and easily recognizable, making it effective in communicating the stop command to operators of cranes and other equipment in a construction or industrial environment. The raised arm and extended palm serve as an unmistakable cue that action should cease immediately, ensuring the safety of workers and the proper operation of machinery.

This position stands out in visibility and is universally understood across various job sites, enhancing communication and minimizing the risk of accidents. Effective signaling is crucial in crane operations where clear communication can prevent potential hazards and injuries.
