Why is there confusion between overpacks and salvage drums?

Traditionally, many manufacturers have referred to salvage drums as “overpacks.” So the industry has
become more familiar with the term overpack than salvage drum and believes that all overpacks must
be salvage drums. This is an incorrect assumption. Recently some manufacturers have been
offering drums that look like salvage drums but refer to them as “overpacks.” Unless your employees
or buyers are very sophisticated on the differences between overpacks and salvage drums under
DOT regulations, they may unwittingly purchase these overpacks believing they are buying drums
they can use for salvage drum applications. If overpacks that look like salvage drums cost less than
salvage drums that could be the first tip that the overpack may not meet the performance standard of
a salvage drum.

Why Is UN Packing Group Important? 

As the correct packaging is crucial for the safe transport of dangerous goods, the UN Model Dangerous Goods Regulations offers a global system for the packaging of substances for the purpose of transport. This system includes a list of UN packing groups for dangerous goods classes and divisions, as well as specific packing instructions for that substance. 

Identifying the UN packing group (and adhering to the required packaging instructions) of your substances enables you to ensure the safe transport of dangerous goods across Australia and the globe. 

How to Assign UN Packing Group? 

There are three different packing groups, each representing a specific degree of danger. The 3 UN packing groups are: 

Packing Group I: Substances presenting high danger 
Packing Group II: Substances presenting medium danger 
Packing Group III: Substances presenting low danger 

But how do you assign a packing group to your dangerous goods? 

To understand the packing group of your dangerous goods, you must first refer to the safety data sheet of your substances. This will inform you of the dangerous goods class or subdivision of your chemicals. 

 You can then refer to the Australian Dangerous for the Transport of Dangerous Goods by Road & Rail (ADG) Code to learn more about the assignment of packing groups for each dangerous goods class and subdivision.

1. What is the difference between an “overpack” and a “salvage drum”? 

Put simply, overpacks are used to protect non-leaking packages, and salvage drums are used with leaking or defective containers. 

 Salvage drums look almost identical to overpacks, but they are stronger and meet even more stringent performance requirements than overpacks. When containers are placed in salvage drums, they must be surrounded with absorbents that are capable of soaking up any leaks that could occur during shipment. 

2. What is an Overpack Salvage Drum? 

Sometimes, a container is dual-rated as both an overpack and a salvage drum, and may be labeled as an “overpack salvage drum.” When a container of this type is ready to be shipped, the inappropriate marking should be removed. For example, if it contains an intact container, the words “salvage drum” should be removed or indelibly covered. After that, the proper shipping name, orientation labels and the appropriate word – “overpack” or “salvage drum” – must be written or attached to the container. 

3. What are the Ultra-Overpacks made of? 

The overpacks are made from low-density polyethylene.  

4. What is the significance of UN marking? 

The UN markings on Ultra-Overpack Salvage Drums can tell you things such as what type of hazmat can be shipped, the material the overpack is made of and the year and country of manufacture. For more information click here. 

5. What are the slots in the top of the lid for? 

The slots in the overpack lids are designed to be used with 50 x 101mm wooden beams. By sliding the 50 x 101mm into those slots, it is much easier to apply torque on the lids to ensure that they are tightened to the required amount. Please note that the use of a 50 x 101mm is NOT required and lids can be tightened by hand.
