Fire raged through two floors of a county office building Saturday, injuring three people and forcing 45 workers to flee.
The fire on the seventh and eighth floors of the 12-story Los Angeles County Health Department building caused office windows to shatter and fall into the street. Heat could be felt a block away.
Fire chief Donald Manning said one firefighter and one worker were treated for smoke inhalation, and a fire captain was cut by broken glass. None was injured seriously.
All of the 45 workers in the building were accounted for about two hours after the fire.
Officials said they didn't know how the fire started but said a lack of sprinklers allowed it to get out of hand before 250 firefighters brought it under control. The building was constructed before a city ordinance made sprinklers mandatory.
The building, about 20 years old, houses county health records and staff for the county's hospital system, employee Pete Cascarono said.
The exterior of the structure was used in the television series Quincy.
