GLASSBORO — An unexpected chemical reaction set off alarms in Rowan University's Science Hall Wednesday afternoon but caused no fire or other emergencies, university spokesman Joe Cardona said.

The incident was initially dispatched as a building fire around 5:30 p.m. in the facility that fronts Route 322 on Rowan’s Glassboro campus.

A student conducting an experiment mixed several substances, Cardona said, and the reaction set off the alarms, which then set emergency protocol in motion. No injuries were reported.

Area fire companies, along with Rowan and Glassboro police, ambulances and other area emergency responders, arrived. As of about 6:30 p.m., two fire trucks were parked just outside the Science Hall, which stands about where the former Bosshart Hall, the campus’ old science building, once stood.

Other fire trucks and emergency vehicles stood by in the parking lot just west of the Science Hall and the adjacent Westby Hall.
