CHICAGO (STMW) -- No one was injured during an extra-alarm fire at a vacant building on the South Side Sunday morning.

At 5 a.m., a still and box alarm fire was called for a three-story vacant building at 6619 S. Union Ave., Fire Media Affairs spokesman Quention Curtis said. A fire was immediately escalated to a 2-11 alarm.

No one was injured, Curtis said.

The fire was extinguished at 5:42 a.m.

A 2-11 alarm sends at least eight engines, four trucks, two tower ladders, five battalion chiefs, a district chief, a deputy district chief, a squad company, an ambulance and the Command Van to the scene.
