JACKSON (AP) — Federal investigators are gathering information one day after an explosion killed an Alabama man and injured three others at copper tubing plant in northeast Mississippi.

Itawamba County Coroner Steven McNeece says 29-year-old Phillip Cason Hosch, of Sulligent, Ala., died in the blast about 4 p.m. Wednesday at Mueller Copper Tube in Fulton.

Memphis, Tenn.-based Mueller Industries confirmed three people were injured, but did not release any details on their conditions.

A spokesman for the Occupational Safety and Health Administration said his agency had sent officials to investigate the blast.

The plant was evacuated following the explosion and the fire was extinguished about an hour later. John Hansen, president of manufacturing operations for Mueller, said the blast occurred during maintenance that initiated a fire at the facility.
