BRIEF DESCRIPTION OF ACCIDENT
A contract employee was assigned to sandblast the inside of a reactor vessel during turnaround activities at a petrochemical refinery. Instead of relying on the contract company's own air compressors in accordance with the contractor's policy, the contract foreman connected the employee's supplied air respirator to a hose containing what he thought was plant air. Instead it was nitrogen. Both hoses were identical except for markings at the shutoff valve. The sandblaster entered the vessel, descended to the bottom, placed the respirator hood on his head and was overcome.
ACCIDENT PREVENTION RECOMMENDATIONS
- Employers must instruct employees to recognize and avoid unsafe conditions associated with their work (29 CFR 1926.21(b)(2)).
- Contractors should follow a policy of using only their own air compressors or breathing air cylinders for their employees.
- Middle and/or upper management personnel should routinely check first line supervisors to insure they are following established company safety policies.
