Read the following passage and answer questions -

Back pain and injuries may vary from one person to another. While eliminating back pain entirely may not be possible there are many approaches to reduce work related back pain. Repetition caused injuries such as respecting certain movements can lead to muscle fatigue and/or injury. Having poor posture, such as slouching, exaggerate your back's natural curve which could also result in muscle fatigue and injury. Smoking should be avoided, because both the smoke and nicotine cause spine to age faster than normal. It may be feasible to eliminate the hazardous motions or change the position of the object in relation to the employees body, such as adjusting the desk or adjusting the height of the shelf (OSHA, 2015). The next engineering control to take would be to minimize the weight, range of motion and the frequency of the activity being performed. Pushing the materials is always recommended rather than pulling them in order to reduce effort and make the work less strenuous. When storing equipment and materials, it is important to store heavy objects at the waist level to prevent any exerted force by picking up the material, rather than storing them lowest towards the ground or at knees or high levels, like, at the shoulder level. OSHA suggests actions to be taken at three levels, first, at the worker's body control measures, second, engineering controls and third, administrative controls like rotating employees, utilizing two person lifts and offering frequent breaks at work.
