SAN FRANCISCO—A house fire broke out in San Francisco Tuesday, July 21, at 1254 33rd Avenue. Firefighters indicated it began after 7 p.m. at the house near Golden Gate Park. San Francisco firefighters first reported it as a 1-alarm fire.

Smoke and flames were visible from the roof and white exterior. Interior crews reported a compromised floor.

The fire moved from a 1-alarm to a 2-alarm classification by the San Francisco Fire Department once the severity increased. A 2-alarm fire calls for four trucks, instead of three for a 1-alarm,  equipped with water pumps and hoses, each manned by four firefighters. Three personnel units would also accompany. Each additional alarm warrants for one more truck and personnel unit.

Firefighters contained the fire a little after 8:30 p.m. The San Francisco Fire Department reported no injuries and asked the public to avoid the area.
