When shipping dangerous goods, only the shipper knows the potential perils that a packaging might face. Many in industry assume that if they are in possession of UN tested packaging and a packaging test certificate, they have met the requirements of the regulations concerning the packaging of dangerous goods. However, nothing could be farther from the truth! The UN requirements state that in addition to the appropriate packaging test selection, shippers should consider the mode of transport as well as conditions of climate when choosing a packaging. Failure to select the right package for a journey is often the result of shippers assuming that UN packages will perform their job unimpeded. Although the principal cause of leaks in transport is usually due to handling, initial package selection for other types of failures is critical. Therefore, when purchasing a packaging, specifically a steel drum, a shipper must request more from a drum supplier than “I want an X drum for a product.” The shipper should request “ an X rated drum for a product which will be shipped all over the world and needs a packaging that will minimally meet the UN criteria and will not be unduly affected by vibration, temperature, pressure, various types of handling equipment, and the like.” In all, the selected package must be able to successfully transport the contents safely to their destination. A cushion of safety is wise to incorporate into every drum purchase.
