Emergency crews in Yonkers responded Saturday morning to a chemical-based three-alarm fire at a Yonkers warehouse.

It’s the second time this month that crews responded to a fire and hazmat situation at 143 Woodworth Ave – a household beauty products warehouse.

Assistant Fire Chief PJ Goldfeder said the fire was sparked by a reaction from stored chemicals and is a “full hazmat assignment.”

According to Goldfeder, the first calls came in around 3 a.m. He says crews on scene witnessed smoke but no flames - and later realized it was from a chemical reaction coming from inside the warehouse.

"At approximately 7 a.m., there was an exothermic reaction causing the fire behind us," he told News 12.

There have been no reported injuries.

Pictures from the scene show large plumes of smoke above the neighborhood, which is close to a train station.

News 12 will have more as the situation develops.
