Ergonomic Risk Factors
Ergonomic Risk Factors : are elements in the workstation, work environment, or job design that are causally related to injury or that can be correlated with risk of injury. Noted below are most common risk factors. Repetition has two components of measurement: (1) the continuous or patterned activity (activity that occurs in a pattern of steps) in which the entire cycle is completed within 30 seconds or less, and (2) the percentage of time during a work shift in which the repetition occurs. Postures are measured in a general assessment of "awkward" or "fixed" as well as by evaluation of specific body parts in both the upper and lower extremities. Forceful Exertion represents three categories of measurement: (1) pinch grip, (2) power grip and (3) push/pull. Vibration measures include impulses from handheld tools or machinery as well as whole body vibration. We document the occurrence, frequency, duration and potential for complications from vibration. Environment issues that we measure are lighting and temperature. Other factors affecting the total environment, such as noise and air quality, are not included in our measures. Work Pace/Productivity entails control over work pace and productivity, which plays a big part in the safety of the work environment. Forced speed or daily productivity guidelines may encourage poor body mechanics and increase potential for injury. Lifting, which could be classified under repetition, duration or exertion, has its own category because of the significance of occurrence
