Document Summary
Chapter 5 214-216: mechanical hazards: many workers are exposed to the range of synthetic organic chemicals, metals, dust and fibers sometimes unknowingly. Hazards of the mechanical nature are a more visible cause of injury and death on the job. Most injuries are not fatal never more than 250 non-fatal occupational injuries for every death. Less dramatic than acute outcomes are the chronic impacts of exposure to vibration or repetitive work. A worker who uses a jackhammer experience is vibration throughout his or her body especially in the hands and arms. Overtime such vibration can damage nerves and blood vessels in the fingers with loss of strength and grip. Workers who do repetitive tasks examples such as production line or keyboard may experience musculoskeletal disorders including tendinitis or carpal tunnel syndrome in which inflamed tissues press on their causing pain and weakness in the hands.
