Science experiment at TSU prompts evacuation

HOUSTON – A science experiment at Texas Southern University Tuesday prompted an evacuation of the science building, officials said. 

Around 11:23 a.m. firefighters were called to the fourth floor of the science building after they said an experiment involving Acetyl Chloride, a colorless, fuming liquid with a pungent odor came into contact with water.

Officials said the chemical can irritate the eyes and mucous membranes. 

"You have to know your chemicals you don't want some chemicals to come in contact with water because a reaction occurs," Department of Chemistry Dean John Sapp said. 

There were no reported injuries or damage.
