Which occupant is allowed to have any part of their body outside the personnel platform?

The signalman is the only occupant allowed to have any part of their body outside the personnel platform because they are responsible for communicating with the equipment operator during lifting operations. Their position often requires them to have an unobstructed view of the load and path of travel to ensure safety and proper direction.

This role is specifically designed to function safely while performing communication tasks. Signal personnel are trained to maintain awareness of their surroundings and to abide by safety protocols which allow them to extend their arms or head outside the platform to provide clear signals to the operator.

The other occupants, such as the operator, crew leader, and safety officer, typically must remain within the confines of the personnel platform for safety reasons, as being outside increases the risk of accidents or falls during operations.
