Safety Alert: Mobile Crane Operator Seriously Injured On Woodyard

A mobile crane was traveling through a mill’s woodyard with the boom in the raised position, rather than in the fully lowered position. This was a recipe for disaster.

Background:

        On a fall day in the Eastern U.S., a mobile crane was traveling through a mill’s woodyard.

 

Personal Characteristics:

        The mobile crane operator was in his mid 40s and had worked in mill maintenance for about ten years.

 

Unsafe Act and Condition:

        The crane was traveling with the boom in the raised position, rather than in the fully lowered position. The crane passed underneath a run of conduit, piping, and lines. The operator failed to notice that the boom was not lowered enough to clear the piping.

 

Accident:

        The raised boom came in contact with a sawdust blow line. The blow line piping separated at a heavy, ceramic-lined elbow, which quickly rotated downward and penetrated the crane cab’s side window, struck the operator, and exited through the windshield.

 

Injury:

        The crane operator suffered head, neck, and shoulder lacerations, along with severe hand injuries that required multiple surgical treatments.

 

Recommendations for Correction:

    • The boom and hook of a mobile crane should be returned to the stored/resting position prior to beginning travel from one spot to another.

    • Ensure that all employees are aware that violating mobile crane boom securement policies creates an unstable and potentially life-threatening condition.

    • Follow equipment inspection and operation procedures consistently and accurately.

    • Re-evaluate equipment and work practices periodically, and conduct periodic refresher safety training classes.
