Which individual is allowed to hand any part of their body outside the personnel platform, according to OSHA 1926.1431?

The signalman is the individual allowed to hand any part of their body outside the personnel platform, as per OSHA regulation 1926.1431. This regulation recognizes the signalman as the designated person responsible for directing the crane operator during lifting operations. The signalman's position often requires them to have a clear view of the load and the area around it, which may necessitate extending their limbs beyond the personnel platform to provide accurate hand signals to the operator.

This allowance is contingent upon proper safety measures being in place to minimize risk, such as ensuring that the area is clear of hazards and that the signalman maintains communication with the operator. The signalman plays a crucial role in ensuring safety during operations, thereby justifying the specific exception for them compared to other personnel involved in crane operations.
