Ergonomic Guidelines for Selecting Hand and Power Tools

Guidelines for tool use ...

"Hand tools have been in existence since prehistoric times. The transition from the primitive Flintstone-era stone wedges to sophisticatedly engineered tools has changed the way work is performed today.

These advances in tools also have created new challenges involving the complex interactions between users and their tools. Improper hand tool selection has been known to result in injuries, variable quality of work and decreased efficiency and productivity.

Using the wrong tool – or using the right tool incorrectly – can cause work-related musculoskeletal disorders (WMSDs). WMSDs are injuries of the muscles, tendons, joints and nerves that usually manifest over a period of time and can affect a variety of body parts. Risk factors associated with the use of hand tools that can increase the risk of WMSDs are awkward wrist and hand postures, static muscle loading, mechanical stress, vibration, noise, torque, temperature and pinch points. When you eliminate – or at least minimize – exposure to these risk factors, you reduce the risk of WMSDs for the worker."   continued ...   (Via Occupational Hazards)
