A "valve malfunction" resulted in a boron trifluoride leak, state police said. The gas has a "pungent, suffocating odor," according to the Occupational Safety and Health Administration.

Video from the scene posted by state police showed a white cloud billowing from the facility.

Hazardous materials crews responded and successfully contained the leak after about an hour, authorities said.

Six employees at the business, three first responders and one employee from a nearby business were transported to area hospitals for treatment due to exposure, police said. They are in stable condition and their injuries are believed to be non-life-threatening, police said.
