Dozens of first responders rushed to the Greyston Bakery on Alexander Street in Yonkers Friday after an apparent explosion.

Crews say there was an explosion inside the bakery's maintenance shop and then a small flash fire.

News 12 is told two workers were taken to the hospital and treated for very serious burns.

Firefighters, with the help of some workers, were able to bring the fire under control.

While officials say the explosion does not appear to be suspicious, they say there may be some Occupational Safety and Health Administration violations.
