Psychological Egoism Refuted, Again

A New Jersey roofer jumped into a vat of nitric acid solution to save a co-worker who had fallen 40 feet into the tank, fire officials said.
Rob Nuckols, 51, was working on the ground floor Monday morning at Swepco Tube LLC when his colleague Martin Davis plunged through a roof and into the vat of diluted acid and became fully submerged, officials said.
He jumped into the vat and was waist-high while he and three others pulled Davis out, Clifton Fire Chief Vince Colavitti told The Record of Woodland Park. The vat contained a 40 to 70 percent nitric acid solution used for cleaning metal tubing.
