IRVINE — Three people were safely evacuated Tuesday night, Feb. 6, from a UC Irvine classroom laboratory following a chemical release, according to authorities.

The incident was reported at 7:37 p.m, in the 300 block of Engineering Court, Orange County Fire Authority officials said.

“The students were working with some chemicals when there was a reaction causing the chemical release,” said Capt. Steve Concialdi.

The three people in the classroom escaped without injury, he added.

About 30 OCFA firefighters and hazardous materials specialists responded and were being assisted by Newport Beach firefighters.

The classroom was returned to UC Irvine officials for use around 9 p.m.

“The spill dissipated and there is no evidence of any harmful chemical left in the classroom,” Concialdi said.
