Lessons Identified

WHAT CAUSED IT:

• The lowboy deck pin that should have been in the roll pin pocket was never found.
• The load slid to the side, as it was being winched ahead. There did not appear to be any reason to winch the load ahead since the tub was now positioned in the middle of his trailer.
• The injured worker didn’t recognize his position as being in a danger zone.

Incident Recommendations

CORRECTIVE ACTIONS: To address this incident, this company did the following:

• JSAs for loading were reviewed and revised to ensure workers do not stand between loads while one is being winched on.
• Workers, in the area of winched loads were reminded that only one load can be winched on at a time so that all workers in the area could concentrate on one load at a time.
• Preparing another load is will not be done within 20 ft. (6 m) of a load being winched or loaded until the load is securely in place on the trailer.
• Drivers were reminded that the deck pins should be in place prior to loading.
• Unless there is a soft spot under the load, all drivers were instructed to roll back under loads as they are winching the load onto the trailer deck.
