Some 26 firefighters from South Salt Lake and West Valley City battled a basement fire for more than an hour Saturday before finally getting it under control.

The 4:40 a.m. fire displaced a family of six and three other adults from the two-apartment structure, 230 E. 2155 South, South Salt Lake Fire Chief Steve Foote said. No one was injured.Firefighters arriving at the scene Saturday morning saw lots of smoke, but had trouble finding the location of the fire because the basement entrance was in the rear of the building. When they did discover it, the fire was burning very hot and putting out a lot of smoke, leaving firefighters with "zero visibility," Foote said.

At one point, the basement ceiling began to sag and firefighters had to pull out of the building. Basement fires are difficult to fight because there is usually only one doorway to the area, making them extremely dangerous, Foote said.

The cause of the fire is still under investigation.
