New York (CNN) -- The injury-plagued Broadway musical "Spider-Man: Turn Off The Dark" has been cited for two safety violations by the State Department of Labor following a series of on-stage accidents, including a spill that hospitalized one of the show's actors in December.
One violation was a safety line that was not attached to the stage -- a snafu that led to a more than 20-foot fall by one of the show's stunt actors on December 20, Department of Labor spokesman Leo Rosales said.
Christopher Tierney, 31, suffered four broken ribs, a hairline skull fracture, a broken shoulder blade, a bruised lung, three cracked vertebrae and broken bones below his elbow, his father said.
The second violation was a misplaced raised portion of stage that caused two accidents last fall while actors were rehearsing back flips, Rosales said.
The two citations were issued Friday.
"Spider-Man" spokesman Rick Miramontez said the $65 million production is in full compliance with Department of Labor guidelines and "will continue to work with state officials to maintain the highest safety standards at all times."
Labor Department officials will make surprise inspections to ensure that all safety measures are in place, Rosales said.
The show, which is currently in previews, has delayed its opening date five times. It is now set to debut March 15.
