HOUSTON (AP) - A company official says four people were killed and six injured when a crane collapsed today during routine maintenance at a southeast Houston refinery.
All were contract employees working at the Lyondell-Basell refinery.
The company was preparing to do routine maintenance on one of the units at the refinery.
Lyondell-Basell vice president Jim Roecker says the crane, operated by Deep South Crane & Rigging, was not scheduled to be active today. But he says the engine was on after the crane hit the ground.
About 1,500 contract workers are employed at the refinery.
