What safety measure should be confirmed regarding the load before a lift?

Confirming the weight and dimensions of the load is essential for ensuring that the lift can be executed safely. This information allows for proper calculations to be made regarding the crane's lifting capacity, ensuring it is not overloaded, which can lead to tipping, mechanical failure, or accidents. Understanding the dimensions also helps in planning for the space required to maneuver the load, avoiding obstacles and ensuring that there is a clear path for a safe lift. Overall, this measure plays a critical role in risk assessment and operational safety during lifting operations.
