Question

By tapping his fist on his ____, the crew member is telling the crane operator to use the main hoist?

1) Head
2) Chest
3) Shoulder
4) Leg

Answer 1

Tapping the chest is a standardized hand signal to the crane operator to use the main hoist, which is an important safety communication protocol on noisy construction sites.

Step-by-step explanation:

In the context of crane operations and signals, the crew member is communicating with the crane operator using standardized hand signals. When a crane operator sees a crew member tap his chest, it is a signal to use the main hoist. This signal is part of a set of established safety communication protocols to facilitate clear and efficient non-verbal communication on construction sites, thereby helping to avoid accidents and misunderstandings. Using hand signals is crucial for safety in environments where noise levels may make verbal communication difficult.
