What action should an operator take if they cannot see the load during operation?

When an operator is unable to see the load during an operation, the safest and most appropriate action is to stop operations and utilize a signal person. Communication is vital in ensuring the safety of the operation, and a signal person can provide clear visual signals and guidance that the operator, who has limited visibility, cannot obtain on their own. This helps to prevent potential accidents or hazards that could occur from misjudging the load's position.

Relying on sound or guessing the load's position is unreliable and can lead to dangerous situations, as they may not accurately reflect the load's location or movement. Using auxiliary equipment might seem beneficial, but it doesn’t address the core issue of visibility. Stopping operations and enlisting the help of a trained signal person is the most effective way to ensure safety and maintain control of the load.
