Example: Risk Factors Answers

The risk factors occurring when this task is performed are checked on the left side of the form, while the x's on the body figure indicate the most likely body parts that may be affected by this task.

The poor postures observed include bending the wrist from side to side and up and down. The workers also maintain a static posture by sitting during most of the work shift. The pressure point or contact stress occurs when the workers rest their arms against the sharp edge of the control table. Because the workers operate the controls during the entire shift, this task is considered repetitive work. Sometimes the workers hold and move the control with a forceful grip.

If you did not identify these risk factors, go back to the previous page and watch the video again. See if you can tell when all of the risk factors occur.
