An Overpack is an enclosure used to provide protection or convenience in handling a package, or to consolidate two or more packages. Overpacks are not the same as Salvage Drums and are only meant for non-leaking packages. If an Overpack drum is sold as a Salvage Drum, the DOT will hold the manufacturer and distributor liable and both parties could face a fine. The DOT does, however, expect a level of knowledge from the shipper and can hold them liable if they do not meet the proper requirements or misuse a drum.
So when should you use an Overpack Drum?
According to UN criteria and standards, Overpack Drums are certified as secure outer packaging. They are tested for solids and should not be used if the integrity of the inner package has been compromised.
An Overpack can be simply defined as a larger container into which a smaller one may be placed. An Overpack can be made of any material, the traditional choice being a 55 gallon metal drum. Overpack Drums come with their own set of UN and DOT requirements, but passing leak and pressure tests are not always among them. More often than not, Overpacks are used to facilitate the handling of another package or two. Skolnik, however, does pressure test Overpack Drums. Our Stainless steel Overpack Drums have each been tested at 1A2/X plus 15 psi hydrostatic pressure per CFR 49 for the over-packing of Toxic (Poisonous) by Inhalation packaging. But despite this rigorous testing and the fact that Skolnik products are made thicker, heavier and stronger than industry standards require, the DOT would still not consider our Overpack Drums as Salvage Drums.
But fear not, if it is a Salvage Drum you need, Skolnik can still help. Both our Overpack and Salvage Drum lines come in a variety of capacities, meet domestic and international regulations and offer extreme durability.Tags: barrel transport, hazardous materials, hazmat containment, overpack, overpack drums, overpack vs salvage, secondary spill containment, skolnik industries, steel drum, when to use an overpack
