Materials Handling Installation & Repair Pulling and Feeding Wire Connecting and Fastening Using Tools Digging and Trenching Prefabrication Supplemental Info. Installation and Repair Installation and repair tasks performed around the worksite can be demanding. Employees often dig trenches or pull long runs of heavy gauge wire. These tasks may require working in awkward postures since much of the work is done at ceiling height, close to the floor, or in cramped service areas. Working in these postures increases the amount of force employees must exert to perform these tasks. Employees may assume awkward postures while using hand tools such as pliers, crimpers, and side cutters for installation and repair tasks. This may create tension and contact stress to the tendons and nerves of the hands and lower arms. All of these potential situations may result in musculoskeletal problems if employees are not aware of the risk and do not take precautions to minimize hazards.
