When can new signals be used for crane operations?

New signals can be used for crane operations if they have been demonstrated to be as effective as standard signals. This ensures safety and clarity in communication between the ground crew and the crane operator. It is essential that any new signals provide the same level of understanding and reduce the potential for accidents or miscommunication during crane operations.

Using signals that are not effectively recognized by all parties involved can lead to dangerous situations. Thus, the requirement for demonstration ensures that all personnel are trained and aware of the new signals, maintaining a high safety standard in landscaping operations. The adherence to established practices helps to promote a common language on the job site, which is critical for the safe operation of cranes.
