What action does the hand signal with forearm vertical and forefinger pointing up indicate?

The hand signal with the forearm held vertically and the forefinger pointing up is a universally recognized signal in the context of operating hoisting equipment, indicating the action to "raise tines" or lift loads. This gesture is clear and straightforward, allowing operators and crew members to communicate effectively even when there may be noise or limited visibility on a job site.

In this signal, the vertical arm positions the hand in a way that visually communicates upward motion, which can be crucial for ensuring safety and coordination among workers. Proper understanding and use of these signals are part of maintaining safety protocols on construction sites.

Other signals, such as stopping or pausing, are communicated through different gestures, ensuring that each action has a distinct and understandable representation to prevent confusion among operators and ground crew.
