Madison fire said cleaning cabinets led to a hazmat situation at drug manufacturing company, Mentor Biologics, in Research Park.
"Three people were in the room where the leak got into," said Madison fire chief, Art Price.
Chief Price said they inhaled fumes from chlorine dioxide, a highly toxic chemical.
"It's in a gassiest form. It leaked into another room. They noticed it because they could smell it. They immediately left the room, dialed 911," said Price.
Madison Police had Science Drive closed off for a couple of hours as hazmat and fire crews went inside.
"Our teams are going in to monitor the air to make sure everything's alright," said Price.
The three people exposed to the chemical were taken away in ambulances to UW Hospital.
"They were all alert and oriented," said Price.
Chief Price said the chemical was contained to the building and will clear up on its own.
"It's going to dissipate. The air handler scrubs it, and it releases into the atmosphere," said Price.
Science Drive was reopened around 8:00 p.m. No word on the conditions of the three people in the hospital.
