what risk factor is present while lifting boxes and loading them onto a truck?

The primary risk factor present while lifting boxes and loading them onto a truck is exerting excessive force. This can lead to muscle strain, back injuries, and other musculoskeletal disorders due to improper lifting techniques or handling loads that are too heavy or awkwardly shaped. Additional risks include awkward postures such as bending and twisting, repetitive motions causing strain injuries, slips, trips, falls, and crush injuries if boxes shift or fall during loading. Proper training, ergonomic practices, use of mechanical aids, and maintaining a safe and organized environment are essential to minimize these risks and prevent injuries during the lifting and loading process.
