SUN VALLEY (CNS) - A building that warehouses ammunition for movie shoots caught fire today, and the firm's 80-year-old owner suffered serious burns, a firefighter said.

Los Angeles city firefighters said they heard exploding ammunition and called a ``greater alarm fire'' after the blaze broke out at 11:18 a.m. at 10648 Elkwood St., just off the northern end of the main runway at Bob Hope Burbank Airport, said firefighter Katherine Main.

Firefighters had the fire out within 36 minutes of their arrival. Main said the building housed Hollywood Engineering, which supplies munitions for movie shoots.

Paramedics rushed the building's owner to an area hospital with nonspecified serious injuries. His name was not released.

Traffic on the nearby Golden State (5) Freeway slowed as Los Angeles city firefighters went into defensive positions, to prevent the fire from spreading to other buildings in the industrial area. The building was described only as a one-story commercial structure.

Burbank Airport police assisted in traffic control on at the corner of Clybourn Avenue and Elkwood Street in Sun Valley.
