A 30-year-old man died Friday after being crushed beneath a metal conveyor structure while working on top of a silo in Petaluma, officials said.
Authorities did not identify the man, who reportedly worked for dredging company Lind Marine.
Petaluma firefighters were dispatched around noon to 100 East D St., where bystanders saw a large metal tower on top of a silo collapse and heard someone screaming for help, according to fire officials.
Police used a patrol car to smash through a locked gate. Rescue efforts involved Rancho Adobe Fire, Sonoma Valley Fire, Sonoma County Sheriff’s Office, California Highway Patrol and Cal/OSHA.
Firefighters climbed to the trapped man using a 35-foot ladder and lifted the metal structure enough to free him. The victim was flown to a local hospital, where he died.
