A blaze at a Brooklyn warehouse that was originally called in at 6:30 a.m. Saturday eventually grew into a seven-alarm fire, with more than 100 firefighters called in to contain the flames in freezing temperatures.

The four-story warehouse contained paperwork and patient records from at least 100 hospitals, giving the flames plenty of fuel to light up the sky throughout the day.

The fire department has said the fire could smolder for several days.

No Brooklyn hipsters have been reported injured.
