Protect Your Family From Machinery Hazards

It is difficult to list all of the examples of accidents that could happen if you get too close to working equipment. Machinery hazards can be classified into four main categories by the kind of injury it causes. Knowing about pinch points, wrap points, cut points, and crush points will help you prevent injuries from most farm machinery. These points cause thousands of injuries every year.

Hazard Points on Machinery:

• Pinch Points are found wherever two pieces of machinery move together and at least one of them moves in a circle. One example of a pinch point is where a drive belt contacts a pulley wheel. When your hand is near one of these areas, the drive belt can force your hand into the pulley.
• Wrap Points involve a part of the machine spinning at high speeds. A Power Take-Off Shaft (commonly called a PTO) is the main cause for these kinds of injuries. You should never go near a piece of machinery that has a PTO running. A frayed shirt, loose clothing, or long hair can be caught or wrapped up in the PTO shaft.

  

• Cut Points can be found where two moving edges slide across one another, or a single edge slides across a stationary edge. Mowers, combine heads, and forage choppers are examples of machinery that have cut points. Most machinery does not have to be moving for you to be injured. The edges are very sharp so they can cut grain, grass or hay. You can be injured by falling onto the combine header, hay mower or rotary mower. Grain augers are used to move small grains, like corn or soybeans, from gravity wagons to storage bins.
• Crush Points injure people when a part of the body is squashed between two pieces of moving equipment. Sometimes only one piece of equipment has to be moving. For example, you can be caught between the tractor and the piece of machinery you are helping to hitch. It is possible to be crushed between the ground and a piece of hydraulically controlled equipment that has suddenly lost pressure. Another common crush injury happens when you roll a piece of equipment (like a garden mower or All-Terrain Vehicle) on top of yourself while operating on a steep hill.
