Kelvin McGibbon became trapped under a fork lift truck while he was working in the stores at the firm’s Dalton Airfield Industrial Estate works in North Yorkshire.
He was flown to Leeds General Infirmary but was pronounced dead a short time later.
A police spokesman said: “At this stage the death is being treated as a tragic accident and no one else is being sought in connection with the incident.”
A spokesman for the contractor said: “At this moment our thoughts are with Kelvin’s family.
“A full investigation is under way and until this is completed the company is not in a position to comment any further.”
