What kind of hazard could arise from improperly lifting heavy objects?

Improperly lifting heavy objects primarily leads to ergonomic hazards. These types of hazards are associated with the physical stress and strain that improper lifting techniques can place on the body, particularly the musculoskeletal system. When workers lift incorrectly, they may experience injuries such as strains, sprains, and other musculoskeletal disorders, which are common in occupations that require manual handling of heavy loads. Ergonomic hazards can result from repetitive movements, awkward postures, or excessive force, all of which are often seen in situations where lifting is involved.

While physical hazards generally encompass a broader category that includes risks like slips and falls, the specific risks of improper lifting directly relate to how it affects the worker's body. While chemical, biological, and physical hazards may also pose risks in workplace environments, they do not specifically address the injuries and issues arising from poor manual handling practices the way ergonomic hazards do. In summary, the primary concern with improperly lifting heavy objects is the ergonomic risk it presents to the individual performing the lift.
