Top Work-Related Injury Causes

The top three leading causes of work-related injuries – overexertion and bodily reaction, slips, trips and falls, and contact with objects and equipment – account for more than 84% of all nonfatal injuries involving days away from work.

Overexertion and bodily reaction includes:

    • Non-impact injuries: Result from excessive physical effort directed at an outside source; common activities include lifting, pushing, turning, holding, carrying, or throwing
    • Repetitive motion: Microtasks resulting in stress or strain on some part of the body due to the repetitive nature of the task, typically without strenuous effort such as heavy lifting


Slips, trips and falls include the following types of events:

    • Slips and trips without falling: Injuries occurring when a worker catches him/herself from falling due to slip or trip
    • Falling on the same level: Includes tripping, slipping, falling while sitting, and falling onto or against object on the same level
    • Falling to a lower level: Includes falling from a collapsing structure, falling through surfaces, and falling from ladders, roofs, scaffolding or other structures
    • Jumping to a lower level: Different from falls because they are controlled and voluntary


Contact with objects and equipment, including:

    • A moving object striking a worker
    • A worker striking against an object or equipment, including bumping into, stepping on, kicking, or being pushed or thrown onto an object
    • A part of a worker’s body being squeezed, pinched, compressed, or crushed in equipment, between shifting objects, between stationary objects, or in a wire or rope
    • A worker being struck, caught, or crushed in collapsing structure, equipment, or material
    • A worker being injured as a result of friction or pressure between the person and the source of injury
    • A worker being injured from vibration
