BERKELEY -- A man was injured in an apartment fire Monday morning, but he is expected to survive his injuries.

Fire crews put out the blaze at the single-story complex that houses five units in the 2300 block of Acton Street. The apartment's resident was taken to a hospital with smoke inhalation and some minor burns but is expected to be OK, Berkeley Fire Chief Gil Dong said.

The fire, which started around midnight, was burning in the entry way to the unit when crews arrived, Dong said. Crews extinguished it before it spread to other parts of the complex.

Investigators are still trying to piece together what started the blaze, which caused approximately $25,000 in structural damage and $5,000 in property damage, Dong said.

At least one media report indicated the injured man tried to put out the fire himself with a hose, but fire crews could not confirm that.
