What should be avoided when lifting a load with multiple points of contact?

When lifting a load with multiple points of contact, avoiding uneven lifting is crucial because it can lead to instability and swinging of the load. When a load is lifted unevenly, the weight distribution is imbalanced, which can cause the load to sway or swing during the lift. This swinging poses safety hazards, as it can lead to loss of control and potential accidents, damaging the load, the lifting equipment, or injuring personnel nearby.

The other considerations mentioned, such as using more than one sling, performing the lift in adverse weather conditions, and using equipment not designed for the load, are important safety factors in themselves. However, uneven lifting directly affects the immediate stability and control of the load during the lift and is particularly critical in scenarios involving multiple points of contact. Maintaining even tension across all points of contact helps ensure a smooth, controlled lift, minimizing risks associated with movement and sway.
