Ergonomic hazard

Ergonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system due to poor ergonomics. These hazards include awkward or static postures, high forces, repetitive motion, or short intervals between activities. The risk of injury is often magnified when multiple factors are present.

Environmental, operational, or design factors can all negatively impact a worker or user; examples include whole-body or hand/arm vibration, poor lighting, or poorly designed tools, equipment, or workstations. Some of the common body regions where injuries may occur include:

• Muscles or ligaments of the lower back
• Muscles or ligaments of the neck
• Muscles, tendons, or nerves of the hands/wrists
• Bones and muscles surrounding the knees and legs

Injuries in these and other parts of the body could result in musculoskeletal disorders (MSDs), which may be called cumulative trauma disorders (CTDs) or repetitive strain injuries (RSIs), and are estimated to account for about a third of all non-fatal injuries and illnesses and their associated costs.^[1] Ergonomic hazards occur in both occupational and non-occupational settings such as workshops, building sites, offices, homes, schools, or public spaces and facilities. Finding ways to eliminate or reduce ergonomic hazards in any setting will ultimately reduce the risk of injury.
