Liquid spewing out of the ceiling disrupted class late in the morning on Nov. 4 and set off the fire alarm in the Humanities Building, witnesses said.

The liquid, later identified as an anti-freeze agent, seeped through the ceiling and onto the third floor of the building.

Occupants of the third floor were evacuated.

According to police reports released by officer Doug Little, a leak caused by climate control in the cooling system is what resulted in the one to three gallons of water-based anti-freeze agent that left the floor visibly wet.

Student Stephenie Reynelds was evacuated at the time and witnessed the leak. “We were in class watching a movie and the [fire alarm] lights went off,” Reynelds said. “I heard water and saw liquid coming out of the ceiling. They told us to go outside and we waited and class was canceled.”

Many students and professors did not know what was going on. “I wasn’t sure what happened and water was dripping down,” said Professor Edmund Chang, who was teaching at the time.

Others reacted to the leak like Lui de la Parra and his class after their substitute professor realized what the leak may be. “The Professor said it smells like a Freon leak. We decided to open the windows,” de la Parra.

Classes were canceled on the third floor from when the fire alarm sounded, at 10:57 a.m., until 12:30 p.m., after the area was thoroughly cleaned.

Proper precautions were put into place and no one was exposed to hazardous conditions, according to Little. “The product sheet said it was not hazardous” and also had “our environmental groups check it,” according to Little.

The liquid was then cleaned up by University officials and by an outside company called Best Climate Control. The Best Climate Control clean-up company could not be reached for comment before deadline.
