Fairfield Fire Department responded to a smoke condition at Metal Specialties on Commerce Drive around midnight. Firefighters found an odd-colored flame and realized it was a chemical reaction taking place in the plant. Firefighters quickly retreated and called in the Fairfield County Hazmat Team. Fire officials tell us everything worked to plan, the public was never in danger and the building was vented and metered at all times. Fire department turned over the property back to the owners around 3am.
