HACKENSACK, N.J. — The City Fire Department and Mutual Aid spent Sunday afternoon battling a problematic fire at Newman’s Fish Foods, which fire officials say was not suspicious.

The vicinity of Elizabeth Street was engulfed in heavy clouds of smoke this afternoon when a second-turned-third-alarm blaze tore through the wholesale and supply store after noon Sunday.

Firefighters rushed to the structure after 12:30 p.m. to find heavy smoke billowing at a distance. Upon entry into the building, flames were running the roofline in the structure, according to Hackensack Fire Captain Justin Derevyanik.

The blaze wasn't going down without a fight.

“Several hand lines were placed in service through a bay door to knock down heavy pockets of fire,” said Derevyanik.

Firefighters struggled with severe water issues due to limited access for apparatus on the dead end juxtaposing the building, and also had to evacuate the building at one point within the two-hour job due to the threat of a collapsing roof which had a dip in it.

The fire quickly turned into a third alarm and additional resources and mutual aid from surrounding towns were summoned to the scene. A host of large hose and master streams operated from the exterior knocked down a large portion of the blaze. At this point, companies reentered the structure to finish extinguishing the fire. One firefighter was hurt.
