Caught-in or Caught-between Objects

Agricultural Tailgate Safety Training for Operators and Supervisors
Agriculture and Natural Resources
Agricultural Safety and Health Program

Objective: To understand why injuries involving being caught-in or between objects occur and how to prevent them.

Trainer’s Note

Share the following scenarios concerning caught-in or caught-between incidents and discuss the reasons they occur and how they could be prevented. Review the true or false quiz.


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

  • Working on moving equipment.
  • Working under mental or physical stress.
  • Using unsafe equipment.
  • Lack of training or instructions. 
  • Inadequate guarding on machines.
  • Incorrect hitching practices.

Examples of caught-in and caught-between injuries:

  • While hauling hay, a worker stopped to change a flat wagon tire. The wagon fell, pinning the worker between the ground and the wagon.

  • Two people were working on a combine when it fell off a jack, the workers were caught under the combine.
    • Never work under equipment that is supported only by a jack. The jack could tip and the raised equipment then will be dropped on the person under it. (Refer to the module “Safe Use of Jacks.”)
      Line drawing of the dangers when working between PTO and shielding
  • An employee removed the shields on the PTO for repairs but failed to replace them after service. Another employee got caught in the PTO.
    • After servicing, all PTO shields should be re-placed for safe operation. Snug-fitting clothing should be worn when working around a PTO. This will prevent clothing from being caught in the PTO. (Refer to the modules “Safe Use of the Power Take-off" and “Power Take-off Shielding.”)
  • When unhitching a wagon, a farmer forgot to chock the wagon wheels, and was caught between the shop wall and the wagon when the wagon rolled forward.
  • A farm employee forgot to chock the livestock trailer when unloading cattle and was caught between the trailer and the corral gate.
    • While unloading or working on equipment, the wheels of equipment need to be pinned to hold them stationary. This procedure is called chocking. By chocking the wheels, the equipment will be unable to roll and cause injury. (Refer to the module “Chock and Block.”)
  • While hitching a loaded hay wagon to a tractor, an employee was caught between the wagon and the tractor.
    • When helping someone to hitch equipment or an implement to a tractor, you should stand to the side and be clearly visible to the person driving the tractor. If you are standing in between the tractor and the equipment, you could easily be crushed between the two.

Review The Following Points

  • Importance of using guards.
  • Know how to properly operate equipment.
  • Use caution when working with moving equipment.
  • Importance of proper chocking techniques.
  • Always follow safe operating procedures.
