PASSAIC - The Red Cross says that 107 people are displaced after a Friday morning fire tore through a Passaic apartment building.

Firefighters battled the heat as they worked to get the five-alarm fire under control.

Officials say 31 of the 32 units in the building were occupied. The Red Cross says all 31 families were affected by the fire. The organization assisted them with food and clothing as needed.

Multiple floors inside the building collapsed as a result of the fire. A small portion of the roof collapsed into the building.

The fire was first reported at around 9:00 a.m. in an apartment building on Gregory Avenue. The building is across the street from the Passaic High School.

Firefighters from 15 communities in two counties were called to the scene.

Chief Patrick Trentacost says nine fire fighters were hospitalized for heat exhaustion and one EMS supervisor was treated for smoke inhalation. Five civilians were also treated for smoke inhalation and other minor injuries.

Students at Passaic High School were evacuated to Lincoln Middle School as a precaution. Classes were eventually canceled for the day. A public library across the street was also closed for the day.

The city of Passaic has established the Senior Center as a temporary shelter for residents impacted by the fire.

The fire was declared under control as of 2 p.m. Friday.
