What communication method must be confirmed between the operator and signal person before lifting operations begin?

In lifting operations, clear and effective communication between the operator and the signal person is critical to ensure safety and prevent accidents. The requirement for confirming a specific communication method before beginning operations stems from the need for precision and understanding in a potentially hazardous environment.

Voice signals are particularly important as they allow for immediate, real-time communication and can be clearly understood over the noise of machinery or environmental factors that may inhibit visual or written cues. When voice signals are agreed upon and confirmed, both the operator and the signal person can quickly relay pertinent information, such as the need to start or stop a lift, adjust the load, or communicate any issues that may arise during the operation.

In contrast, other methods like hand signals, written communication, or visual signals may not provide the same level of immediacy or clarity necessary in fast-paced lifting situations. Hand signals can be misinterpreted, especially from a distance or if visibility is poor. Written communication can be delayed and is not practical for instantaneous communication needed during lifting operations. Visual signals might also lose effectiveness in adverse weather conditions or high-noise environments where sightlines are obstructed.

Therefore, confirming voice signals is essential for ensuring that both the operator and the signal person are on the same page before lifting begins, thereby
