Ergonomic Hazard Assessment
Using the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment brought some new perspective to conducting a risk assessment. Not only are the normal controls looked at for caught by, struck by, entrapment, etc. but these two assessment brings into question body movements and how they could be affected by Work Related Musculoskeletal Disorders (WMSDs). Using these assessments changed the way that my Hazard Assessment looks. I added two new columns for each category so I can get a total. I now can use the total to give this job and overall score. If there are was to reduce the risk with the individual task then the overall score will reduce. Thus, other jobs at the mill can be compared and risk can be evaluated. I like the fact that it uses a scoring system and you have something that can be looked at and reduce the WMSDs risk factors. I used two step-by-step guides for the RULA and REBA from ergo-plus too figure out what my scores would be in my Hazard Assessment.
