If a person makes contact with the volatile chemical, symptoms could include burning skin and respiratory problems, Smith said.

No one suffered any injuries, but the fire alarm was triggered and the building evacuated. Buckman Drive, from Union Road up to the Chemistry Lab Building, was closed for about two hours.

One person was escorted out of the building because he didn't hear the alarm, said Tim Hayes, deputy fire chief of the Gainesville Fire Rescue's Risk Reduction Bureau.

The safety features built on campus, such as sprinkler systems and hood systems, help in times of chemical spills, Hayes said.

Smith said the chemical evaporated and left the room quickly thanks to the hood system inside of the lab.

After exiting the building, the suited Hazmat team members were washed off as part of a decontamination process, unsuited and their vital signs were taken, Hayes said.

If any one of them showed symptoms, they would immediately be transferred to a medical facility by one of the rescue units that were on standby, he said.
