What type of signals should a signal person be familiar with?

A signal person must be familiar with both standard hand signals and specific signals for the equipment being used. Standard hand signals are universally recognized in the construction and rigging industries, enabling effective communication between operators and signal persons, especially in noisy environments where verbal commands may not be heard clearly. Additionally, different types of equipment may have unique signaling requirements tailored to their specific operations, so understanding these signals is crucial for safety and efficiency on the job site. This comprehensive knowledge ensures that the signal person can effectively guide the actions of equipment operators and ensure that lifting and moving operations occur safely.
