CARLSTADT, N.J. —  Authorities say a factory worker was seriously injured when a large pile of steel accidentally fell on him.

The incident occurred around 9:20 a.m. Wednesday at a bed frame company in Carlstadt. Authorities say the 56-year-old man's legs were pinned under the pile but he was alert and conscious as rescue crews worked to free him.

The man was rescued about an hour later and was taken to a hospital. Authorities say he suffered "extensive" leg injuries, but his name and further details on his condition have not been disclosed.

Authorities say a ceiling hoist was being used to move a bundle of steel when it somehow lost its load and it fell on the worker.

The federal Occupational Safety and Health Administration is investigating the accident.
