SAN FRANCISCO (AP) - San Francisco fire officials say three workers were seriously injured when scaffolding attached to a home collapsed.
Fire spokeswoman Mindy Talmadge says the workers - three men ages 24, 50 and 58 - fell about 25 feet on Friday morning.
At least two of the men's injuries were considered potentially life threatening. Television news footage of the broken scaffolding showed a makeshift wooden platform that appeared to be nailed to the side of a home.
Police Capt. Mike Caplan told KGO-TV that no permits had been issued for the work.
Talmadge did not know who, if anyone, the workers were employed by. She said the California Division of Occupational Safety and Health will investigate the incident.
