The second $7,000 citation faulted the company for not using breathing-air couplings that were incompatible with the nitrogen pipeline, which would have prevented the accident.
The agency issued 10 other "serious" citations for a variety of safety violations, such as using equipment not certified for hazardous locations and failing to develop safe work procedures and written instructions for emergency shutdown. Most of these citations carried $4,900 penalties.
In addition, OSHA issued five nonserious citations for problems that must be fixed but with no proposed penalty.
Blake McEnany, assistant area director for OSHA in Charleston, said the office issued its citations to AC&S on Dec. 20 and the company received them the next day. The company has not yet responded, he said.
"AC&S has a responsibility to ensure that its workers are safeguarded from workplace hazards, and by not properly labeling its gas systems, failed to protect a worker who ended up losing his life. That is intolerable," Prentice Cline, director of the Charleston office, said in a news release.
"OSHA's standards are designed to prevent this kind of tragic incident," Cline said.
A woman who answered the phone Thursday at AC&S referred calls to Aly Goodwin-Gregg of Charles Ryan Associates, who issued a written statement Thursday afternoon.
"The OSHA investigation following the tragic accident that occurred in our Railcar Cleaning Division in June of this year concluded with recommendations for improvement and safety citations for the company," the statement said. "As safety is paramount, we began working with OSHA immediately following the accident to address its concerns and do all that we can to ensure that this type of accident will never happen again.
"The loss was very difficult for all of us within this small company and our greatest sympathy goes to the family of Rex Wilcoxen. We have counseled and supported our employees as we have dealt with the loss of a friend and co-worker."
