The Basics of UN Drums

Proper packaging is crucial, especially for dangerous goods. Using the wrong container to transport or store your goods can have a disastrous impact on your facility, community, employees and the environment. With countless manufacturers and transportation companies across the globe building and utilizing industrial containers everyday, there needed to be a level of regulation and oversight in the packaging and transportation industry. One of those levels of regulation comes from the United Nations.

For a drum to be UN approved and rated it needs to be built, tested and certified to contain liquid or solid dangerous materials. Only packages that are certified to have passed the UN packaging standard tests may be used to transport dangerous goods.

A few basics on UN drums and the regulations that surround them:

UN drums are tested against drop, stack, leak and pressure standards. UN performance standards are an internationally recognized system of ratings for solids and liquids.

All UN certified drums are marked with a code that indicates the physical nature of the product for which they are suited. This code always starts with the letters “UN” in a circle. This marking is permanent.

There are three dangerous goods packing groups. The first (packing group I) refers to UN Drums and barrels such as those manufactured by Skolnik. This packing group is built to the highest standard.

It is the shipper’s legal duty to select and fill packages correctly. It is also the shipper’s duty to ensure that packages are marked accordingly. Shipping container packers should check that packages are properly marked and, if they are not, should not transport them. But the responsibility of proper selection falls on the shipper.

Do you know what UN rating your materials need? Skolnik can help you understand the UN ratings and guide you to the packaging suited for your use. What’s more, Skolnik UN drums are built stronger and thicker than the industry standards require.

Overpack Container Regulations At-A-Glance

An overpack drum is a type of protective packaging manufactured to contain non-hazardous or hazardous materials or provide outer protection for another container to prevent or mitigate damage. At its most basic definition, an overpack is simply a large container in which another smaller container can be placed. Overpacks can be made out of any material — such as Skolnik’s steel overpack drums. The Department of Transportation (DOT) regulates the movement of all hazardous materials and have specific performance standards that overpack containers must meet.

Not to be confused with Salvage Drums or Salvage Overpack Drums, Overpacks are designed to protect non-leaking containers or to be used as a combination pack.

Because they are designed to provide additional protection, they are built stronger and must meet more stringent requirements than other containers.

So what are a few of those regulations?

  • Overpack containers must always have a UN marking on them that specifies the type of hazardous materials it is certified to contain.
  • An overpack will never have a liquids rating because it is designed to hold another container — a solid. Regardless of what the inner package contains, the overpack technically contains a solid.
  • The container inside an overpack must be intact — if the container is damaged, defective or leaking you must use a salvage drum.

Salvage drums, on the other hand, are certified to hold damaged, leaking or non-compliant containers and are held to even stricter regulations than overpack drums.

These are just a high level overview of the DOT’s overpack regulations. Remember that preparing hazardous materials for shipment can be complicated, and safety and compliance are key. Reserve the task of packing your hazardous materials for someone who has the appropriate DOT hazmat shipping training.

Skolnik Industries TIH (PIH) Overpack Drums range from a 20 gallon overpack to an 85 gallon overpack drum and are certified according to UN criteria and qualify as secure outer packaging. If you have any questions about using an overpack or salvage drum, don’t hesitate to ask your Skolnik representative.
