When installation workers are required to drill or screw planking or flooring, such as with trailer floors, the worker must be in a lowered kneeling, stooped or crouched position so that the worker can operate a handheld drill to drive self-tapping screws into the planks or flooring so that it is held in place on the flooring support structure. Being in such a lowered position for prolonged periods becomes fatiguing and can lead to back or knee pain or injury.
