A corroded pipe and decades-old regulations cause catastrophe at Philadelphia Energy Solutions

Today's topic is a news story from earlier this year regarding the fire and explosions and ultimate shuttering of the Philadelphia Energy Solutions oil refinery. The official word from the U.S. Chemical Safety and Hazard Investigation Board is that a corroded pipe fitting, found to be half the thickness of a credit card at its thinnest point, led to that incident. The concern is that the pipe, which was installed when Richard Nixon was president -- 1973 -- went all this time without being properly checked.
