The man was working at A&A Concrete Supply Inc., 10250 Linne Road, around 3:30 p.m. when the incident occurred, according to David Bramell, division chief with the Tracy Fire Department.
Bramell said the victim worked for Express Chipping, based in the Los Angeles area, which was contracted by A&A Concrete Supply to clean the inside of its mixers. Over time, concrete can dry and harden in the drums, he said.
“In the course of that process, he chipped off a large piece that pinned him inside the drum,” Bramell said.
Other workers in the area immediately realized what happened and began to try and free the man. However, he was trapped by a piece of concrete estimated to weigh about 1,800 pounds, he said.
Firefighters arrived on the scene but were not able to remove the rubble from around the man until about 4:50 p.m. His body was removed from the mixer, which is mounted on the back of a truck, around 5:05 p.m., according to Bramell.
“After people accessed him, we determined that the injuries he had sustained were fatal, so then it switched to a recovery operation,” he said.
A medical helicopter was spotted flying over the scene around 4 p.m. however it never landed.
Firefighters were also seen carrying tool boxes and a hydraulic pump capable of lifting large pieces of concrete.
Bramell didn’t release the name of the victim.
Express Chipping was permitted to do the work, and no regulations appeared to be broken, Bramell said.
