In terms of lifting safety, what type of signals must be adhered to and not conflict with special signals?

Adhering to standard signals during lifting operations is essential for maintaining safety and ensuring effective communication between the crane operator and the signal person. Standard signals are universally recognized hand signals or flags that convey specific commands related to the lifting process, such as raise, lower, or stop. These signals help create a clear line of communication to prevent misunderstandings that could lead to accidents.

When standard signals are in place, they provide a consistent framework that all individuals involved in the lifting operation can understand, which is crucial in a dynamic and potentially hazardous environment. If special signals—used for specific circumstances or unique instructions—are introduced, they must not conflict with standard signals to prevent confusion. Maintaining this clarity ensures that all personnel can respond accurately to the signal, thereby enhancing overall safety during lifting operations.
