An explosion at a New Jersey warehouse sparked a two-alarm fire and hurt four people Monday evening, authorities say.
The fire started when two chemicals were accidentally mixed at the Crest Foam factory at 100 Carol Pl. in Moonachie, officials said.
The plant's president, Mike Bessette, said there was a loud boom, and the explosion caused ceiling fixtures to fall down. The building was then evacuated.
There were 17 workers inside the building at the time, and all were accounted for.
Four people sustained minor injuries and were taken to Hackensack University Medical Center for treatment.
The fire has been extinguished, but investigators are expected to stay on the scene until Tuesday. It's unclear if the building will need to be torn down.
There are no risks to anyone in the area, officials said. Neighbors were initially advised to close their windows and leave the area as a precaution.
