A lift with incomplete load and communication information
A precast element is ready for transport, but its current mass, center of gravity, and suitable attachment points have not been confirmed. A lifting accessory shows a visible defect, and a worker without the relevant training offers to attach it after reading a short summary of the rules. The intended path crosses an occupied access route. During a preliminary coordination exchange, the radio connection becomes unreliable. Wind is also changing. The foreperson must distinguish equipment availability from a suitable controlled lift. No load chart, geometry, wind limit, or attachment design is supplied, so the case cannot authorize a real lift or provide a universal numerical limit for the operation.
1. Identify the operational prerequisites.

Establish actual load information, suitable authorized attachment points and lifting arrangements, serviceable accessories, appropriate trained personnel, clear communication, controlled hazard area, and relevant equipment and environmental conditions. Reading a summary does not replace required training.
2. What should happen if communication fails during the operation?
Read the worked answer
Bring the operation to a safe state and restore agreed reliable communication before proceeding. Do not rely on guessed signals. Apply the relevant lifting plan and equipment limits rather than invent a universal wind or capacity threshold from the case.
