Manual lifting is the pushing, pulling, and movement of heavy weight objects. It's a common part of everyday activities for workers, including contractors and employees in some manufacturing sectors.
The dangers of manual lifting come from the regular overexertion that it causes. This can result in soft-tissue damage and musculoskeletal disorders, such as rheumatoid arthritis. Overexertion also increases the risk of accidents, such as falls or collisions with other objects. In extreme cases, manual lifting can lead to death.
