A chemistry building at University of Maryland College Park was evacuated Wednesday morning after an experiment caused a classroom fire, leading 17 people to be taken to a hospital for evaluation, authorities said.
People were conducting a lab experiment when a chemical reaction caught on fire at the Chemical & Nuclear Engineering Building, campus police said. Prince George's County Fire & EMS were called about 11 a.m.
The fire was extinguished by a powder extiguisher, a fire department spokesman said.
Multiple people were transported for precautionary evaluations, the fire department said: four students, a contractor, an employee, eight Prince George's County Fire personnel, two members of the campus police department and an assistant fire marshal. A spokesman initially said there were no reports of injuries.
Firefighters worked to clear the building and make sure all fire was out. The building was being ventilated by a fan.
The fire department said about 2 p.m. that they were preparing to clear the scene soon.
Campus police asked people to avoid the area and follow police directions.
