CHELSEA -- A man in his 30s was killed this afternoon when a freight elevator he was working on at an industrial building fell on him, police said.
The accident happened about 4:10 p.m. at State Garden Inc. at 360 Beacham St. in the city's produce warehouse district, said Police Chief Brian Kyes.
The man had rigged the elevator to stay up while he was working on it, Kyes said.
"It appears he was working on an elevator, doing some kind of work on it, and it just kind of gave way," Kyes said.
Kyes said the man worked for State Garden, not for an elevator repair company. "I don't think that's his specialty," he said.
Investigators from the US Occupational Safety and Health Administration, Chelsea Police, and the Suffolk district attorney's office are on the scene, he said.
A message left for Mark J. Demichaelis of Winchester, who is listed in state records as president of the company, wasn't immediately returned.
