What are the reasons for stopping personnel lifting operations, EXCEPT?

Stopping personnel lifting operations is essential to ensure the safety of all involved. The correct choice highlights a situation that does not necessarily mandate halting operations as it pertains specifically to tag lines, which are used to control the movement of the load rather than the safety of the personnel being lifted. While tag lines are important for maintaining control over a load and can enhance safety, their absence does not inherently compromise the safety or structural integrity necessary for personnel lifting.

On the other hand, malfunctions of critical equipment, an impending weather hazard, and lost communication are all serious issues that directly impact the safety of both workers on the ground and those being lifted. Equipment malfunctions can lead to an inability to control the load, dangerous weather can create hazardous lifting conditions such as high winds or lightning, and failures in radio communication can prevent effective coordination during lifts, all of which require immediate cessation of operations to protect personnel.
