Agriculture is a labor-intensive occupation that involves a hands-on approach to every work day. Safety precautions need to be considered when working around farm equipment or livestock. If precautions are not taken seriously, it is easy to be caught-in, caught-between, or struck by objects, leading to serious injuries. People with limited mobility, lack of range of motion, or diminished reaction time are at higher risk.

Caught-in or Between Accidents

OSHA lists "caught-in and between" accidents as one of the big four workplace hazards. The most common caught-in and between accidents are workers being caught in machinery. Others include buried in a trench and pinned between equipment and another solid object.

Caught-in or between incidents occur for some of the following reasons:

  • Working on or around moving equipment.
  • Working on equipment with stored energy. (example: hydraulic cylinder)
  • Inadequate guarding on equipment or guards have been removed.
  • Incorrect hitching practices.
  • Not being visible to the equipment operator.
  • Being unaware of approaching danger in the work environment.
  • Uneven lighting with bright spots and shadows causing livestock to balk.
  • Approaching an animal in its blind spot.

Some guidelines to prevent caught-in or caught-between incidents should include:

  • Being familiar with the equipment to know where the pinch, shear, wrap, and crush points are located, as well as the pull-in areas.
  • Always shutting down equipment before doing repairs or inspecting of equipment.
  • Chocking the wheels on equipment that could move or roll.
  • Never working under equipment supported only by a jack. Use a secondary support device.
  • Using the cylinder safety locks on equipment that support hydraulic cylinders, to prevent the releasing of stored energy in the cylinder.
  • Making sure all guards are in place and properly secured after servicing equipment.
  • When hitching or unhitching equipment, standing to the side, and being clearly visible to the tractor driver.
  • Leaving an escape route to prevent being pinned between two objects.
  • Taking extra caution when working around equipment that uses belts/pullies, chains/sprockets, or PTO shafts.
  • Utilizing Roll Over Protective Structures and wearing a safety belt.

Struck-By Accidents

"Struck-by" accidents are related to material handling and housekeeping and occur when work tools, materials, vehicle/machinery, flying debris, or any other type of object hits someone.

Potential struck-by accident hazards include:

  • Tools or loose parts left on window ledges, shelves, or working platforms.
  • Objects leaning against walls, racks, posts, or equipment.
  • Unmarked low beams or pipes.
  • Weak overhead supports or poor stacking of materials. 
  • Slivers from machine tools, breaking glass, or someone swinging a tool without looking.
  • Agricultural processes that involve spreading materials or waste.

Guidelines for eliminating hazards:

  • Do not leave tools or loose parts on window ledges, shelves, or working platforms.
  • Leave guards or screens in place on equipment as it was manufactured.
  • Mark low beams, pipes, and ceilings with proper Low Clearance—Caution signs.
  • Stack and store objects properly.
  • Use the appropriate Personal Protective Equipment for the task at hand.
  • Use falling object protective structures (FOPS) on equipment.
  • Pay attention to your surroundings or work environment.
  • Do not get distracted by conversations.
  • Watch for people carrying objects that block their view of you or their destination.
  • Do not daydream or lose focus of what you and the people around you are doing.
  • Eliminate all horseplay around the work area.
