Testing requirements for companies transporting oil by rail are getting tighter after a spate of explosions caused by crude train derailments in the U.S. and Canada, federal officials said.
A move last Thursday by the U.S. Department of Transportation (DoT) built upon a Feb. 25 order that targeted oil shipments for more stringent testing.
There has always been testing to determine the volatility of oil and other hazardous liquids, but there were no standards on how often that had to occur.
DoT officials are now specifying that within the “reasonable, recent past” companies must test the flash point and boiling point of crude to determine how likely it is to ignite.
Officials are telling companies not to re-label crude as some other volatile product in an attempt to get around testing.
