About 4,500 workers at an IBM plant near Boulder, Colo. were forced to stay inside on Thursday morning after a chemical accident at a nearby Lexmark International printer factory.
The accident, which released a plume of chemical smoke into the air, forced Lexmark to evacuate 150 workers and sent 10 people to the hospital with burning eyes and breathing trouble, according to a report in the Denver Post. About 100 Lexmark employees had to shower in decontamination tents.
Lexmark, which makes laser and inkjet printer, said the accident was caused by workers preparing an epoxy floor coating and had nothing to do with its manufacturing operations. All traffic around the IBM campus, where the Lexmark facility is located, was detoured for two hours and access in and out was temporarily shut. IBM relocated 600 workers away from the contaminated area.
