What Are UN Packing Groups?

November 27th, 2017 by Natalie Mueller

Filed under: Salvage Drum

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. Whether you’re trying to decide which Skolnik brand overpack salvage drum is most appropriate for your needs, or have used the same Skolnik brand overpack salvage drum for years, having a fuller appreciation of the container and its components can provide you with the confidence that you’re making the right choices in your business.

The UN System for Dangerous Goods Packaging

Skolnik steel barrels are all UN tested for their contents/purpose. If a manufacturer or shipper fails to comply with UN standards, they could face hefty fines, litigation and more. It is always important for manufacturers to adhere to UN regulations, but for dangerous goods packaging the stakes are even higher because, in addition to a fine, failure to comply with UN standards for dangerous goods packaging could lead to a spill, disaster or contamination. But what does this mean? How does the United Nations affect packaging regulations?

The UN system for dangerous goods packaging is universally used and recognized. The system is used to classify, package, mark and label dangerous goods to facilitate their safe transport. All national and international regulations governing road, rail, sea and air transport are based on the United Nations’ system. With all manufacturers, suppliers and transport professionals following a single set of rules, the chances of contamination are greatly reduced.

The regulations dictate a minimum standard of performance. These performance standards are based on the intended contents of a package. Packages must exceed these standards before they can be authorized to contain and transport dangerous goods. The UN system starts with a sort of checklist of general criteria and specifications that the design of packages must meet. The packages then undergo rigorous physical testing before receiving UN certification.

At Skolnik, we pride ourselves in consistently engineering and manufacturing steel drums that exceed the UN certification criteria for dangerous goods and other uses. Our industrial packaging is designed and tested to be thicker, heavier and stronger than the industry standard, and our dangerous goods packaging is no different.

Open Head vs. Tight Head Steel Drums At A Glance

July 20th, 2017 by Natalie Mueller

Filed under: Industry News

There are numerous different configurations of an industrial container. When determining which container is appropriate for a specific use, businesses consider the container’s material, gauge or thickness of the material, size, shape, linings, closures, head style, and many more factors. Some of these factors come with a multitude of options, for head style, it is just a choice between two: open head or tight head.

So what is the difference between an open and tight head drum?

An open head container, also called 1A2 drums, has a fully removable cover secured with a Lever lock or bolt ring closure. Tight head drums, also known as closed head or 1A1 drums, have a non-removable top. One can only access the container via a 2” and ¾” plug in the top of the container.

On a tight head drum, the head is an integral part of the drum construction — both ends are flanged and permanently sealed. Because of the limited access to the contents, tight head drums are often used for liquids, especially lower viscosity liquids. For example, Skolnik’s stainless steel wine drums are tight head containers.

Open head drums, on the other hand, are used for a wide array of contents. Skolnik’s lever lock closure drums are UN rated for solids and liquids, particularly thicker liquids such as soil absorbents, syrups, glues, oils, etc. Open head drums are typically used in situations where people need access to the contents, either for frequent addition or extraction.

Skolnik Industries manufactures both open head and tight head steel drums in over 500 configurations, always to UN and DOT certification standards. If you are unsure what style head or closure your contents require, don’t hesitate to ask a Skolnik representative.

Liquids-Certified Overpack Drum

Using a drum that has been tested and certified to hold your particular contents is crucial. If you came to this post looking for details on an overpack container for your liquids, we are sorry to disappoint. Despite the post title, there is no such thing as a liquids-certified overpack drum. Why? Well, that answer is pretty clear once you think about it.

An overpack is a container that makes handling a package more convenient or consolidates two packages that are not leaking. It is designed to hold another container. That other container is considered a solid, regardless of what it is holding inside. Overpack drums are often used in multi-pack situations too. In all cases, the overpack technically contains a solid.

But what if you want to use an overpack drum to contain a liquids-certified package that is leaking? You shouldn’t. Overpack drums are not certified for liquids or to hold damaged packages. The container inside an overpack must be intact, if it is damaged, defective or leaking you must use a salvage drum.

Some sources use the terms overpack and salvage interchangeably, but they are not the same. We have previous blogs that cover the differences between salvage drums and overpack drums in more detail. One of the differences? There is such thing as a liquids-certified salvage drum.
