PHILADELPHIA (CBS) – A fire tore through an apartment building in Philadelphia’s Germantown neighborhood late Monday night, forcing dozens of tenants out into the cold.

Crews were called to the six-story Morris Manor Apartments on the 5700 block of Morris Street, around 11:30 p.m. It is believed the fire started on the third floor.

The flames were brought under control in about an hour, but firefighters were left to deal with ice quickly forming on just about everything. Several cars along the street could be seen completely covered in ice.

Three people were sent to the hospital with minor injuries.

Officials say a total of 40 people were displaced as a result of the blaze.

Two cats also had to be rescued.

“We got them out of the building. Gave them a quick evaluation with their families. And two cats on the first floor are sheltering in place,” said Jennifer Leary with Red Paw Emergency Relief.

“There’s a lot of people who are wheelchair-bound and they needed help to get out, so, fortunately, I’m glad that the firefighters got here as fast as they got or else it would be a real tragic situation,” said one resident.

The cause of the fire remains under investigation.

People are expected to be allowed back in most of the apartments by Saturday.
