SAN FRANCISCO -- Two workers were killed Friday morning at a San Francisco warehouse after large slabs of rock fell and crushed them, authorities said.
Emergency responders received a call about 10:15 a.m. reporting that 10 slabs of rock had fallen on two employees as the slabs were being unloaded from a truck at Galaxy Granite Inc., a stone fabricator in San Francisco's Bernal Heights neighborhood, said Fire Department spokeswoman Mindy Talmadge.
The slabs were in a container attached to the back of the truck, Talmadge said, and the incident occurred while the workers were inside the container.
Rescue crews and company employees freed the workers shortly after arriving, she said.
One was pronounced dead at the scene, and the other at San Francisco General Hospital.
Peter Melton, a spokesman for the California Division of Occupational Health and Safety, said his agency was investigating and that Galaxy Granite had never received a safety citation.
Cal-OSHA has six months to complete its investigation.
It was not immediately clear how heavy or how large the slabs were or what they were composed of; Talmadge reported that they were granite, while Melton said they were marble.
Two people who answered the phone at Galaxy Granite on Friday afternoon did not identify themselves and had no comment on the incident.
