A gas leak forced an evacuation at a Homestead apartment building late Wednesday night.Residents at the building on East Ninth Avenue noticed a strong smell of gas around 11:30 p.m.  Firefighters and crews from Equitable Gas found levels too dangerous to allow anyone back inside.A family -- including a 2-month-old baby and a 4-year-old girl -- was forced to wait outside for about four hours until the building was aired out.The long wait was frustrating for the residents, who said they weren't given good information about how long they would have to stand outside."I'm freezing. There's a 2-month-old baby out here, a 4-year-old.  I took my jacket off for my daughter," Hillary Smith said. "It's just ridiculous because no one has called Red Cross for us. They haven't asked us if we're all right."The residents were allowed back inside around 3:30 a.m.Equitable Gas said the problem appeared to come from a broken pilot light in the range or the furnace, so they had to cut the gas service off until the problem could be fixed.
