Police and fire trucks blocked off Snow Way and the area around Laboratory Sciences Monday night after a chemical spill occurred in one of the building’s labs.

One student had to have his eyes flushed and was driven to the hospital by the police, but was otherwise fine, Washington University spokesman Steve Givens said.

University police cars and four fire trucks from Richmond Heights and Clayton were on the scene at 10:15 p.m. They had been called in at around 8:45 p.m.

The alarms went off while students in LabSci were taking an organic chemistry test.

“The fire alarm went off when there were about 12 minutes of the test left…then the police came and said to get out of the building, and that was with 7 minutes left,” sophomore Michael Harding said. “[The TA] was basically saying that if we were really concerned about the fire alarms we should turn in the tests, but if we were really concerned about orgo we should stay and finish.”

“Everyone went out for a good 20 minutes, and then we moved over to Louderman and took the last 10 minutes of the test. It was just really irregular.”

The Millbrook Garage is still accessible to pedestrians and vehicles.

WUPD officers stationed outside of Laboratory Sciences declined further comment.
