Occupants of a neighboring building reported the blast shortly before 10 a.m. in La Habra, Los Angeles County Fire Inspector Kesith Mora said.

Arriving firefighters found flames showing from the building, he said. The fire was contained in about a half-hour.

The people who were hurt were transported to hospitals with unknown injuries.

The building in a commercial district houses a metal plating and polishing firm. A phone message left at the business was not immediately returned.

The cause of the blast was under investigation.
