Wear clothing that fits well and is not loose or floppy Never reach over or work near rotating parts Turn off machinery to work on it Always replace shields removed for maintenance Wrap Points Rotating shafts are the most common source of wrap point accidents although any exposed machine part that rotates can be a wrap point A cuff sleeve pant leg long hair or just a thread can catch a rotating part and result in serious injury Entanglement with a wrap point can pull you into the machine or clothing may become so tightly wrapped that you are crushed or suffocated In other cases you could be thrown off balance and fall into other machinery parts Even a perfectly round shaft can be hazardous if there is enough pressure to hold clothing against the shaft Hazards increase with shafts that are not round Clothing is more likely to catch if there is dried mud or manure on the shaft 11 Safety Precautions or if the shaft is nicked Ends of shafts that protrude beyond bearings are also dangerous Universal joints keys and fastening devices can also snag clothing Check all equipment for potential wrap points and if possible shield those that can be shielded Replace any damaged manufacturer installed warning labels and place warnings on equipment parts not previously labeled In addition consider painting them a bright color perhaps with wide stripes Be aware of wrap points and be alert to their danger Crush Points
