* Pinch Point is an area where two rotating surfaces meet such as feed rollers, gears or a belt running around a pulley. Extremities can be caught in pinch points directly, or be drawn in by loose fitting clothing that has vecome entangled in the rotating parts.
* Shear Point is an area where the edges of two surfaces come together in a manner so as to cut a softer material placed between the surfaces. Shear points are found on shrubbery shears or grain augers. The resulting injury is usually amputation.
* Cutting Point is found on machinery designed to cut such as mowers and harvesters. The blades move with a rapid motion often unseen by the eye. Injuries are of the same nature as those caused by a shear point.
* Crush Points occur when two objects are joined; either with both ends moving towards each other or with one being stationary. Fingers and hands are often injured by crushing between a draw bar and wagon hitch. Numerous fatalities occur when people helping the operator or the operator him/herself is crushed between pieces of equipment or equipment and a solid object such as a wall or tree.
* Springs are found on numerous pieces of farm machinery. When a spring is compressed, 'energy' is 'stored' within the spring. When the spring is expanded, the energy is released. The larger the spring the greater the amount of energy produced. When springs break they explode with great force and can inflict serious damage. It is important to inspect springs regularly for cracks and wear.
* Wrap Point is any moving point on a piece of equipment where clothing or long hair may become entangled such as a Power Take Off (PTO) shaft. A wrap point grabs the victim and actually wraps him/her around the moving part or it can also draw the victim into the machine. Tangled clothing can wrap tight enough to crush, amputate or suffocate the victim. All wrap points on machinery should be sheilded if possible.
