Home battery backup explodes in Sausalito house

An explosion linked to lithium ion batteries was reported in a Sausalito home. No injuries were reported.

Southern Marin firefighters responded around 2:20 a.m. Monday to a reported structure fire at 30 Atwood Ave.

Sprinklers extinguished a fire in the garage, said Elysha Omoomy Costella, a fire spokesperson. The fire and explosion was traced back to a battery bank used to power the house in the event of a blackout, she said.

Firefighters remained on scene until 7 a.m. Marin County firefighters, Sausalito police, and Pacific Gas & Electric Co. crews assisted, Costella said.
