Two firefighters were injured in a possible explosion in a three-alarm fire house fire Sunday afternoon (Dec. 4) in the unincorporated Emerald Hills area, a fire official said.
The fire was reported at 2:22 p.m. at a three-story, single-family home at 651 Vista Drive.
The firefighters suffered burns to their faces and were taken to Santa Clara Valley Medical Center, Redwood City Fire Department officials said on Twitter at 4:51 p.m.
The firefighters were expected to be released shortly after being treated.
No one else was injured, Cal Fire Assistant Chief Mark Steward said.
The home may now be uninhabitable, Steward said. The residents were not home when the fire broke out and are now staying with family.
Building officials will make the decision whether to deem the house uninhabitable, Steward said.
Firefighters are not sure what exploded. The cause of the blaze is under investigation and fire officials do not suspect foul play, but they haven't ruled it out until investigators complete their work, Steward said.
