A fire caused by a burning mattress at a residential building that also houses a health care facility in San Francisco’s Parkside neighborhood was quickly extinguished Thursday evening, a San Francisco Fire Department spokesman said.

The blaze was first reported around 8:30 p.m., at Kindred Nursing and Rehabilitation at 2043 19th Ave., according to fire officials.

A mattress inside the building apparently caught fire. Once at the scene, firefighters brought the blaze under control within about six minutes, according to fire department spokesman Jonathan Baxter.

The building was occupied at the time, however no residents were displaced and no injuries were reported, Baxter said.
