SAN FRANCISCO (AP) - Fire officials say a 1,000-pound (455-kilogram) rebar tower at a Northern California construction site toppled over, injuring three workers including one critically.
Fremont Fire Battalion Chief Jeff Youngsma said the three workers, all men, were trying to tighten the 20-foot (6-meter) tall tower Wednesday morning when it collapsed on them.
Ambulances transported the man with critical injuries to a hospital. The other two men were treated separately for moderate injuries.
Youngsma said the incident occurred at a construction site in Fremont, California about 45 miles (72 kilometers) southeast of San Francisco.
He said California’s Division of Occupational Safety and Health plans an investigation.
