The finished, inserted paper is then placed in a third stack on the table. After ten papers have been inserted and placed on the finished stack it is lifted, turned on end, and straightened by tamping the paper edge on the surface of the table. The finished stack is then placed on the conveyor. Employees stand for the duration of the task but move freely about the work station. There are two press changes interspersed throughout the shift of about 10 to 20 minutes.
Most employees have other jobs throughout the plant on other days or nights of the week.
Employees perform highly repetitive finger exertions with the wrist in a deviated posture, repetitive torso flexions, and the job entails long periods of standing and holding the shoulders in an elevated postures. It is difficult to determine the absolute number of repetitions, or period of time that a posture can be maintained or an activity performed, which will cause an injury. But the risk of injury is definitely increased as static posture times or uninterrupted repetitions of a movement are increased. Work-rest schedules should be developed and enforced. Generally, a minimum of a 15 minute rest break at least every two hours is required.
