17 people were working in the facility at the time of the explosion.
It was so loud the fire chief, who lives three blocks away, said "It knocked me off my feet."
Ambulances were requested to the scene, and everyone in the building has been accounted for. Three people suffered minor injuries.
Neighborhood residents were advised earlier to close their windows because of chemicals in the air. The chemicals were found to be not threatening to residents in the area however.
