Event description
Three employees hospitalized after exposure to toxic gas
Investigation abstract
Utah Power & Light, the employer, did an air load test on an electrostatic preci pitator after an extended shutdown. The testing was done on the weekend when the contractor was not on site. After the testing was completed, no one turned off the equipment. With no smoke load, the unit became a very efficient ozone genera tor. The contractor went to work Monday morning without checking the system. Sho rtly after the start of the work shift, employees started to experience acute re spiratory problems. Employees #1, #2, and #3 passed out and were transported to a medical facility, where they were hospitalized. Three others showed chronic re spiratory symptoms and were removed with the other employees to clean air.
