As a hazardous materials trainer and consultant for nearly 30 years, I am always amazed by the complacency some companies that ship hazardous materials have towards the gravity of the hazmat regulations. At the risk of sounding like an alarmist, if not done properly, a routine shipment can cost a shipper an awful lot of money.
Time and time again, usually after the fact, the guilty shipper will say things like: "We only ship this stuff occasionally." Are we supposed to gather it's only hazardous sometimes? Or, "We've always ship it this way and never had a problem," assuming two wrongs make a right.
