DOWNINGTOWN, PA (CBS) -- A shelter-in-place order has been lifted in Downingtown, Pennsylvania, after authorities responded to a hazmat incident Wednesday.

Crews were dispatched to the scene at 415 Boot Road in Downingtown just after 10 a.m. for reports of 300-500 gallons of hazardous material spilled inside a facility, officials said. 

Emergency responders noticed a small vapor cloud coming from the facility that dissipated after they arrived. The shelter-in-place was lifted around 11:30 a.m. after it was determined there was no threat to the public. 

The Chester County Department of Emergency Services Hazardous Response Team said the hazardous materials spilled were a mixture of nitric acid and phosphoric acid. 

The incident was placed under control at 2 p.m., officials said. 

There were no major injuries in the incident.

A facility with children inside was located within a one-mile of the radius surrounding the incident, but the children were quickly evacuated to a safe location and their parents were notified, officials said. 

One person was taken to a hospital for evaluation, authorities said.

Recovery and clean-up operations will be determined by the Pennsylvania Department of Environmental Protection and the property owner, officials said.
