Firefighters in Butte battled a blaze Tuesday night  at McDonald's restaurant on Harrison Avenue in Butte.

No one was injured in the fire, but officials say the building is a total loss. KXLF reporter Melanie Yuill who was on the scene says the roof of the McDonald's has collapsed and much of the structure is burnt. But the fire department says luckily everyone got out safely and no one was hurt.

Jeff Miller of the Butte-Silver Bow Fire Department said there were "no injuries to any civilians no injuries to any firefighters."

The fire was reported just before 4 p.m. Employees say customers were immediately evacuated. Smoke and flames poured from the building for hours. Miller says the fire started in the attic of the restaurant.

"It traveled fast. It was way above their head. It gets up in there, there's a big void the fire just traveled very rapidly," he said.

Three fire engines plus a ladder truck responded to the blaze.

"We were in there for a while did what we could then it became too dangerous, so we backed everybody out went to a defensive mode of fire attack," said Miller.

Firefighters worked above the smoke and flames spraying water, tore holes in the side of the building, and sprayed water into the structure through those holes.

"Without a doubt it's a total loss. It's even more difficult when it's a food service. There's standards that have to be kept, so it's pretty well lost," Miller said. He added that the cause of the fire is not yet known but says an investigation will continue.
