What is the potential hazard of not using hand signals correctly?

Not using hand signals correctly can lead to miscommunication, which is a significant hazard in equipment operation and construction sites. Effective communication is crucial when operating machinery, as it ensures that everyone involved understands the actions being taken and can respond appropriately. Incorrect hand signals or misinterpretation can result in the operator moving the equipment when it's unsafe, leading to accidents that may cause injury to personnel or damage to property.

This reinforces the importance of clear communication and adherence to established signaling protocols to maintain safety in the workplace. The other choices, while relevant to different operational considerations, do not directly relate to the immediate safety risk that arises from miscommunication during equipment operation.
