More than 200 firefighters were needed to battle a seven-alarm fire in Manhattan on Monday, after an appliance is believed to have sparked the blaze.

Fire officials said the fire broke out just before 2 p.m. on the second floor of a six-story building on 775 Riverside Drive in Washington Heights, spreading to the building's cockloft.

The FDNY said at least 16 people suffered injuries, but those injuries are not considered life-threatening. Four of those people injured are city police officers, and one is a city firefighter.

The fire was under control around 9 p.m., the fire department said.

The blaze was believed to have begun after a woman was making toast and the electrical toaster malfunctioned and sparked, according to Fire Commissioner Daniel Nigro. Officials said a smoke alarm was present in the apartment.

Officials said the fire caused a partial collapse of the roof.

Before 5 p.m., authorities had advised nearby residents to close windows and avoid smoke.

The building's age played a role in the spread of the fire. Nigro said an open dumbwaiter shaft in the building had the effect of a chimney, as the blaze quickly spread through there and into the cockloft.

A few hours before the fire was under control, authorities said they believed the number of injuries would increase.

The Red Cross sent teams to the scene to register affected residents.

The agency has had a busy past few weeks; the Red Cross said it has helped nearly 700 people affected by more than 150 local disasters since Christmas — and that was before the fire in Washington Heights.
