WICHITA, Kan. (AP) — Wichita police say two men have died at an industrial accident in south Wichita.

The accident was reported Thursday morning at Occidental Chemical Corporation.

They were contract workers at the plant. The men were pronounced dead at the scene. Their names have not been released.

Sedgwick County Sheriff Lt. Lin Dehning says a preliminary investigation indicates some of the men’s mechanical equipment failed.

Dehning says no chemicals were released from the plant and the public was never in danger.
