This involves removing bolts from the flanges which hold the parts together. This is accomplished by loosening the securing nut from the bolt with a pneumatic nut driver or with a closed or open end wrench. All nuts are put back on the bolt by hand and the part is lifted away by an overhead crane after all bolts have been removed.
Employees have frequent and forceful pinch grips and muscle exertions while in awkward postures.
Frequent pinch grips and forceful muscle exertions are consistent with the development of musculoskeletal injuries. While it is not possible to say that a certain number if repetitions of a particular action is hazardous, it is possible to say that the more times an action is performed the greater the chance of injury. Engineering controls for these hazards will be mentioned in subsequent sections as well as some proposed remediation strategies. Administrative procedures that can be implemented to reduce the hazard are mentioned below. Jobs should be classified as to the nature and extent of exertion and a rotation schedule should be created that allows for as much variation as possible in the distribution and frequency of musculoskeletal activity.
