Derailed tanker held toxic chemical

The Richmond Times-Dispatch for December 19, 2020 published the following report to do with a derailment in downtown Roanoke.

The report describes damage to a car containing liquid sulfur. Sulfur is a yellow solid at room temperatures. It is used to make sulfuric acid (the acid in our car batteries). The sulfur is liquefied for transportation and loaded into tank cars. (Its melting point is 115.2 °C / 239.4 °F.)

Liquid sulfur is a hazardous chemical. We there to be a spill, the high temperature liquid could cause severe burns. Also, were it to catch fire, it would generate sulfur dioxide (SO2) fumes that are toxic.
