LINCOLN, Maine (AP) — A co-owner a paper mill in Lincoln, Maine, says a worker has been hospitalized after suffering burns during the mill’s annual shutdown for maintenance.

Keith Van Scotter, co-owner of Lincoln Paper and Tissue LLC, says the worker suffered hot water and steam burns while inspecting one of the tissue machines at the plant on Thursday.

Van Scotter tells the Bangor Daily News the worker’s injuries are serious, but that he’s expected to recover.
