Durham Regional Police say several people have been injured in a chemical spill at a company in Clarington, about an hour east of Toronto.
Police say a tanker truck containing nitrous oxide was being drained Thursday afternoon at Detox Environmental Ltd. on Bennett Road. A reaction occurred as the gas came in contact with an unspecified chemical.
The incident resulted in a smoke release inside the building, which then escaped into the environment.
About 30 employees at Detox, as well as employees of a nearby forklift company, were evacuated.
Several people were harmed after inhaling the spilled chemicals. Two Detox employees were sent to Lakeridge Health Bowmanville – one with serious injuries.
A hazardous materials team is decontaminating the area. Police have closed nearby roads, including the Highway 401 off-ramp.
