A man in his 30s was taken to the hospital with serious injuries Saturday after his arm became caught in a machine at Aloun Farms in Kapolei.

Honolulu fire Capt. Carlton Yamada said the man was almost finished with his shift when he was trying to remove debris from the bottom of an onion sorter with a conveyor belt mechanism. The man’s arm got caught and was pulled into the machine, where it became stuck between the frame and the roller system, causing deep lacerations in his arm.

An Emergency Medical Services supervisor said the man was taken to the hospital in serious condition.

Yamada said firefighters were dispatched to the farm in the 91-1400 block of Farrington Highway at 2:37 p.m. and found others had already freed the man from the machine.
