A WTI worker died last night after a Saturday fire at the East Liverpool facility.
Thomas Bailey, 52, of East Liverpool, was a service technician at WTI, where a container of hazardous waste material reacted Saturday, causing the fire. Bailey and another worker were taken to a Pittsburgh hospital, where Bailey died Sunday night.
"Heritage-WTI is deeply saddened to learn that one of the company's employees passed away late last night in a hospital in Pittsburgh," said a statement released by the company Monday morning.
The second worker, who hasn't yet been identified, is in stable condition.
According to the company's web site, WTI is an "environmental services company that provides advanced incineration of hazardous waste and other materials generated by manufacturing and service industries."
WTI said it has notified the U.S. Department of Labor's Occupational Safety and Health Administration is cooperating with the agency's investigators. A spokesperson with OSHA said its investigation will be complete within six months.
According to a WTI release dated Nov. 21, WTI was issued a license Nov. 10 by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives to treat explosives at its RCRA-permitted incineration facility.
The BATFE issued the license after conducting a thorough investigation of the company and the employees who are eligible to handle explosives. Agency officials also inspected the facility firsthand in September as part of their review, the release states.
The incident is still under investigation.
