Which hand signal is commonly used to indicate “stop” in a dogging operation?

In dogging operations, effective communication is crucial for safety and coordination. A raised hand with the palm facing forward is the standard hand signal for "stop." This signal is clear and easily recognizable, making it an essential tool for operators who may need to halt activities quickly. The open palm is universally understood to convey a firm and immediate instruction to stop, which is particularly important when machinery is involved or when working at heights, as confusion could lead to accidents or injuries. Utilizing this specific hand signal ensures that all crew members are aligned in their understanding and response, thereby enhancing safety on the site.
