Elizabeth, New Jersey fire engulfs large industrial building

ELIZABETH, NJ - A fire that broke out at a massive industrial park in Elizabeth, New Jersey is still burning Friday evening and officials say it could continue to burn for days. 

Officials received a call around 5:30 a.m. after a passerby saw the flames at the park that was the industrial park that was home to the Singer Sewing Machine factory for more than a century and reported it.

No one was in the building and no injuries were reported, Mayor J. Christian Bollwage said.

Two roofs and one wall collapsed, but the fire was burning in several buildings closest to the waterfront, away from the oldest historical portion of the building, Bollwage said.

"The iconic portion of the building is not threatened, nor do we expect it to be," the mayor said.

Video from the scene showed the building engulfed in flames with firefighters surrounding the structure.

More than 100 firefighters were on the scene of the four-alarm fire, a classification requiring one of the highest levels of response in the city, officials said. Mutual aid assistance was being given by numerous area fire departments, and New York City lent firefighting boats to help battle the blaze.

The cause of the fire is under investigation, and the blaze itself could take several days to extinguish, Bollwage said.

Three businesses inside the warehouse were totally destroyed by the flames. 

The building is south of Newark Liberty International Airport and near Staten Island. A huge plume of smoke was seen from Manhattan.
