All of our products here at Skolnik have been rigorously tested to meet every relevant safety standard required for each of their uses. One such regulation standard that containers such as our overpack salvage drums have is a UN marking, providing valuable information about the contents of the drums. While they can be a bit mystifying, we have resources to help answer questions about those markings, and once explained, most of these make sense. Right in the middle of the code there is, however, a letter designation that perhaps needs more elaboration: the X, Y, or Z of the UN Packing Group.
Each letter describes which of groups I, II and III the container is appropriate for. These groups identify the hazard level of the package, with each groups then representing three levels of danger: I is the highest, II is a medium hazard, and III is the lowest rating.Thus, the letter on the salvage drum establishes what level of protection the container provides and what products can be stored in them.
While this letter may be enough information for day to day operations, this leaves one last question still unaddressed: how does the UN determine what is low, medium, and high danger?
The answer to this is found in the very dry and technical Manual of Tests and Criteria, in which UN details their elaborate testing process for various types of materials. Throughout the graphs and charts, one can find that all explosives are assigned to group II. Or if handling flammable liquids, according to the manual, anything that has a flash point greater than 23 degrees Celsius but less than 60.5 degrees is in group III. There are specifications for substances liable to spontaneous combustion, and for ones that, when in contact with water, emit flammable gases. Multiple types of hazards are examined, quantified, and categorized according to how quickly they explode, burn, or corrode.
So, as it turns out, there is elaborate, methodical and thorough science behind these threat-level groups. These categorizations then go on to inform how the materials ought to be stored. While that’s a bit of a reassuring no-brainer, details such as these can easily be overlooked and taken for granted in the hustle and bustle of shipping logistics.
