WORCESTER, Mass. (WHDH) — A fast-moving fire spread through a multi-family home Saturday, forcing firefighters to move quickly to rescue residents trapped inside.

Flames filled the house so quickly, five people could find no way out. They waited for firefighters while hanging out of their windows.

“It looks as if some lives were saved from the actions of our firefighters today,” said Samuel Richesson, Worcester Fire Department.

The three-family home caught fire around 5 a.m. Saturday. The flames started on the first floor but they shot through the roof — leaving people on the top floor stranded.

“Most of the rescues were taken out from the third floor of the building. They were taken out by ground ladder and aerial ladder. This was also done under very heavy fire conditions and very extreme circumstances,” said Richesson.

Fifteen people share the Worcester home. Seven were sent to hospitals to get checked out.

Neighbors watched firefighters work to make sure everyone was quickly accounted for.

“They help people come down and they do a good job,” one man said.

People who escaped the flames looked on from the street while crews doused their house. The three alarm fire took hours to put out.

Firefighters say nothing from the house could be salvaged.

Firefighters are looking into whether a lit candle could have sparked the flames.
