Gov. Phil Murphy and his wife Tammy Murphy offered their thanks to Passaic first responders who fought a massive fire in the city on Friday.

The governor and his wife brought pizzas to the East Side Firehouse on Monday.

The 11-alarm fire decimated the chemical plant and warehouse. Those buildings are being demolished.

Murphy marveled at the coordination that took place to fight the fire and to prevent the fire from spreading to the main building that housed chlorine.

"They came within 15 feet of 2 million pounds or 2 million tons of chlorine, which would have had a catastrophic result. So thank God they were able to push back. They had 100 different communities represented,” Murphy said. “New York City was on standby. This thing was a huge scale, and the heroism and the bravery on display by these folks, it just takes your breath away."

Firefighters were on the scene on Monday checking for flare-ups in the rubble.

Passaic Mayor Hector Lora says that the air quality remains safe in the area.

The cause of the fire remains under investigation.
