A cloud of chlorine gas in a Utah State University animal lab prompted an evacuation Friday and sent two people to the hospital.
The evacuation happened about noon after someone put Virkon, a disinfectant, into an autoclave, according to university spokesman Tim Vitale. Once in the autoclave, the Virkon combined with steam and produced chlorine gas. People nearby then began detecting a burning smell, followed by a chemical odor.
Vitale said fewer than 10 people evacuated an animal research lab. Two people went to the hospital as a precautionary measure, though Vitale said both ended up being fine.
