David Gold Flames erupt as firefighters attempt to enter the 6th Street Kitchen around 7:30 this morning. A second blaze around mid-morning forced another evacuation for the residents of apartments above the restaurant.

Shortly after the tenants of a Sixth Street apartment building were allowed to return to their homes after an early morning fire, they were forced to evacuate a second time while firefighters put out a lingering pocket of flames.

The second evacuation, which occurred around 9:40 a.m., came after firefighters extinguished a blaze that gutted the 6th Street Kitchen, a restaurant located on the ground floor of the building at 507 East Sixth Street.

A Fire Department spokesman said that fire marshals at the scene came across areas that were still smoldering on the first floor. They called for several units to return. “It wasn’t a major operation. It was put out in about 20 minutes,” said the spokesman.

Paul Canetti, 27, who lives on the building’s third floor said that he had returned to his apartment after being allowed back inside by firefighters.

“Within 30 seconds of being in the apartment, we couldn’t breathe, so we said, ‘No, we will not stay here,’ ” Mr. Canetti said. “We went back downstairs. Within five minutes, we hear them radioing for firefighters to come back because the fire was still burning between the first and second floor.”

Mr. Canetti said he and other tenants were again forced to evacuate.

Around 1 p.m., Mr. Canetti said they were let back into their apartments. “The apartment is a war zone. It’s pretty terrible. Everything is knocked over and completely covered in soot.”

The American Red Cross was at the scene and gave disaster relief paper work to the tenants. “They said we should call them if we need a place to stay, and they would put us up in a hotel for a few days,” he said. “I think I’m going to take them up on that because I definitely cannot stay in my apartment.”
