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.

Safe Lithium Battery Containment

Lithium-ion batteries are the most commonly used batteries in consumer electronics and medical devices today, and they have been exploding. For all of the benefits and conveniences, lithium batteries have offered consumers — higher power density, lower memory effect, long life — they have a number of downsides and risks. Their sensitivity can lead to an explosion and, for this reason, they are considered “dangerous goods” and are banned from commercial aircraft.

The result is a kink in the supply line and, for those who rely on medical devices powered by lithium batteries, more than a mild inconvenience. At present, these batteries are only permitted on cargo aircraft and cargo planes only fly to large airports. As a result, the batteries cannot get to their final destinations.

The world isn’t going to suddenly stop needing lithium ion batteries anytime soon, so this is a puzzle that needs a solution. But, you know what they say: Necessity is the mother of invention. Skolnik Industries and Labelmaster have been working together to devise a package that can safely contain spent lithium ion batteries for bulk transport. This overpack package would serve as a multi-pack solution for the batteries as well as a secondary spill containment measure should the batteries be compromised in transit.

While it is always a pleasure to work with our friends at Labelmaster, we’re eager to find a safe and strong solution to this problem. The project cannot be completed until the DOT releases its final testing requirements for these package types, and, as with all Skolnik Industries products, this lithium battery-safe overpack container would be rigorously tested to meet all pertinent DOT regulations.

Once the regulations are set, we look forward to providing shippers and manufacturers with a safe, efficient solution to lithium battery containment, and helping alleviate the delay for those who need battery replacements for their medical devices.

Unpacking UN Ratings: The 1A2 Drum

The shipping and transportation of dangerous goods or hazardous materials is a tightly regulated process — and rightly so! You wouldn’t want to be on an aircraft or train or sharing the roads with just any old material packaged any old way. These materials require a special container that meets criteria set by the DOT and the UN. And, it is the responsibility of the shipper to choose the correct packaging for their materials.

At Skolnik Industries, we’re always happy to help our customers select the best container for their needs. To start, let’s take a look at UN ratings and what they mean.

Many of our products UN rating begins with a 1A, we’ll talk about why that is in a moment, but for the sake of this exploration let’s say that you worked with the team at Skolnik and we discerned that you need a container with a 1A2/X60/S UN rating for your hazardous materials.

First, you’re in luck, Skolnik has several hazardous waste containers that fit that specification.

But what do those numbers mean?

 

Well, the 1 refers to the fact that it is a drum, not a wooden barrel, box, bag or some other type of container.

Here are the UN codes for other containers:

1 – drum

2 – wooden barrel

3 – jerrican

4 – box

5 – bag

6 – composite receptacle

7 – pressure receptacle

 

The following letter tells us the material of the container, in this case an A for steel.

Other material codes:

A – steel

B – aluminum

C – natural wood

D – plywood

E – reconstituted wood

G – fiberboard

H – plastic

L – textile

M – paper, multiwall

N – metal other than steel or aluminum

P – glass, porcelain or stoneware

 

So far we’ve determined that we need a steel drum, our specialty! But what about the second number? This number refers to the drum head. The 2 means that it is an open head drum. (A closed-head drum would be marked with a 1).

We’ve cracked the first part of the code: we need a 1A2 container, or a steel, open head drum!

If you want to dig deeper, our example UN rating was 1A2/X60/S – so what are the other parts?

 

The X designation tells us what level of hazardous materials your packaging can be used for. The rating is either an X, Y or Z. Packing group I is the most hazardous and packing group III is the least.

X – covers hazardous packing group I, II or III

Y – covers packing groups II and III only

Z – covers packing group III only

What a versatile drum we’ve chosen!

 

That next number refers to the maximum gross mass the container has been tested to handle, in our example 60kg. The final S indicates that this is the UN rating for solids for this container (Liquids ratings differ in that they communicate the maximum specific gravity of liquid that the container has been tested to hold instead of mass, liquid ratings also indicate the maximum hydrostatic pressure the container can hold).
So there you have it, when we say you need a 1A2 drum, that means it is a steel, open head drum – the remaining code elements tell you what your container is safe to carry.

Trust the Strength of Steel for Hazmat Transport

There are a lot of requirements and questions that go into choosing the correct drum or container for the job, and that goes double for choosing the correct drum or container for the shipping and transportation of hazardous materials. The first of those questions is “what material container do I need?” If your container needs to travel by plane, train, or automobile (or ships too!) Skolnik’s steel hazmat drums are your friend.

Think about it this way, airplanes, ships, freight trains, and trucks are made of metal. They are specifically engineered to withstand the pressure put on them by increased altitude and turbulence, the raucous waves and long journeys. You’d be rightfully hesitant to board a plastic aircraft. So why would you trust a plastic or fiber container to safely contain hazardous materials at 39,000 feet? Or a plastic container knocking about in the middle of the ocean? Or hitting potholes on the road? Skolnik steel hazmat containers are specifically engineered to withstand the pressure and variables of air, sea and land travel. Whether you are transporting hazardous liquids, solids or gels, steel is strong, durable and equipped for the job.

The UN and DOT have strict regulations when it comes to the safety and construction of aircrafts, ships and vehicles, it is no wonder they have strict regulations when it comes to the transportation and shipment of hazardous materials via those vessels. All Skolnik steel drums under-go rigorous UN and DOT testing for their intended uses. You can trust a steel hazmat drum from Skolnik to meet, or even exceed, any imposed agency standards and carry your materials safely and securely from point A to point B.
