A construction worker fell from the roof into a tank filled with nitric acid at a Clifton, N.J. industrial site.
A co-worker jumped into the tank to help rescue the man who fell.
Fire and emergency personnel were called to Clifton Boulevard on Monday morning.
SkyFoxHD was over the scene Monday morning as emergency response crews examined the tank and the roof of the building.
The man, Martin Davis, plunged nearly 40-feet into the tank, according to northjersey.com.
The men were working on the roof of a metal tube manufacturing plant called Swepco Tube Company.
Davis suffered head-to-toe burns. He was air lifted to Saint Baranbas burn center.
Rob Knucols, the man who jumped in to save Davis, was taken to St. Joseph's Medical Center in Paterson. He has burns on his legs and abdomen.
Four other workers were transported to area hospitals for exposure to the acid. They were all believed to be part of the rescue effort.
