November 29 explosion at Murray State sends 3 to hospital

Via WPSD, a short news item: 

MURRAY, KY — Three people were treated at a hospital and released following a chemical leak at Murray State University on Tuesday afternoon, university officials say. 

According to a Facebook update from MSU, all buildings on the Gene W. Ray science campus will be open on Nov. 30, including the chemistry building — though there will not be any laboratory activities. 

School officials say students with questions should contact a faculty member. 

This was followed up by a piece from the Murray State News (article by Dionte Berry): 

Emergency responders were on the scene of a chemical explosion in the Jesse D. Jones Chemistry Building resulting in the evacuation and temporary shut down of the Gene W. Ray science campus.

The campus body was alerted of a chemical leak in the chemistry building around noon on Tuesday, Nov. 29 and was told to avoid the area. 

Three people were sent to Murray Calloway County Hospital because of the explosion, with one being injured by the explosion said Murray Fire Chief Eric Pologruto. All three have now been treated and released. The extent of their injuries is unknown.

Although the Admin News updates labeled the incident as a chemical leak, Pologruto said the incident was more of a small chemical explosion, which triggered an alarm throughout the entire science campus. 

Pologruto said the explosion was caused by a reaction during an experiment that was conducted. 

There's no other news as to what happened; seems to me that it is unusual for explosions in academic chemistry labs to require medical attention. Sure would be nice to have some details, but it doesn't look like any will be forthcoming from the local media.
