Firefighters responded to a report of a major explosion at a house at 372 Camphor Ave. at about 7:40 p.m., according to the Fremont Fire Department. The first companies to arrive reported that the front portion of the house and a garage had collapsed as a result of the blast, and what remained was fully engulfed in flames.
One person suffered major burns and was hospitalized, according to a report prepared by Battalion Chief Ron McCormick. No injuries to the 20 fire personnel on scene were reported.
The fire was under control by 8:05 p.m., and flames that had threatened neighboring homes did not breach defensive lines formed by firefighters.
The house that burned suffered major structural damage that investigators estimated would rise to around $500,000, with an additional $50,000 accounting for the loss of damaged contents.
Crews will likely remain at the scene for the remainder of the night, McCormick reported early Sunday, as the cause of the explosion and ensuing fire has yet to be determined.
