PITTSBURG, Kan. (AP) — The Occupational Safety and Health Administration is investigating the death of an employee at a Pittsburg plant.

Authorities say 51-year-old Harley Burch Jr. of Pittsburg died Tuesday after being injured in an accident at the Vinylplex plant, which makes PVC plastic pipe products. Lt. Tim Tompkins says Burch was working near a manufacturing machine and somehow came into contact with a piece of equipment.

OSHA spokesman Scott Allen said Wednesday that investigators will interview witnesses and try to determine what caused the accident.
