“2” – “separated from” (normally, CTUs at least 6 metres apart) “1” – “away from” (normally, CTUs at least 3 metres apart) The numbers (1, 2, 3 or 4) will tell the people stowing the goods how far apart they must be separated, as follows: Where they intersect, you will either find the letter “X” or a number. To determine the segregation for two classes, you would read a row for one class (across) and for the other class read a column (down). The table for segregation by class can be found in section 7.2.4, as follows

Can the classes of dangerous goods go in the same Cargo Transport Unit (CTU) or will they have to be placed in separate CTUs so they can be stowed in different areas? (Note that of course if goods can’t be placed in the same CTU, you obviously cannot package them together.) However, let’s concentrate on what the shipper needs to know. There are a number of complexities for the crew of the vessel as to where on the ship dangerous goods of differing classes may be loaded – on deck, next to each other in compartments inside the hull, or in separate compartments.

The rules for segregation by class can be found in IMDG Code Part 7. In other words, if you determine that there are any applicable segregation requirements, you can’t put the two dangerous goods in the same cargo transport unit together, nor may you put them in the same package or overpack. shall not be transported in the same cargo transport unit…” “Dangerous goods which have to be segregated from each other according to the provisions in chapter 7.2. The most important thing to remember when planning a marine load is section 7.3.4.1, which states that: Shipper and carrier knowledge of the substances involved.Substance-specific guidelines based on codes found in the List of Dangerous Goods, IMDG Code Volume 2.A generic segregation-by-class table found in section 7.2.4, IMDG Code Volume 1.This has led the International Maritime Organization (IMO), which created the IMDG Code, to develop a system that relies on three steps of protection: So, it’s important to keep chemicals from mixing during the trip. And marine carriers transport millions of tonnes of dangerous goods per year. Well, if you’ve ever seen a ship at sea in a storm, you’ll understand how chemicals could mix if they both leak at the wrong time. Basics of IMDG Segregationįirst, why is segregation so important for marine shipment. Not following these rules can result in your shipment being stopped at the port if you’ve mistakenly combined two substances that the Code has classified as requiring segregation. But the most complex system for segregation is that for marine shipments under the International Maritime Dangerous Goods (IMDG) Code.

system have a detailed table indicating classes that have to be shipped on separate vehicles, those which may be shipped without restriction, and those which may be shipped on the same vehicle but must be separated to prevent commingling in case of an accident. On the other hand, the Hazardous Materials Regulations (HMR) in the U.S. For example, Canada’s Transportation of Dangerous Goods Regulations (TDG) doesn’t have any specific guidelines other than a table in section 5.7 that only applies to class 1 Explosives. Different regulations will have different requirements. Unfortunately, the solution isn’t always easy to find. A shipper may have two different chemicals – can they ship them in the same packaging? Or even in the same freight container? The answer is important because having to separate parts of a shipment can increase the cost of transport by a lot. One of the most common issues we get asked about at ICC The Compliance Center is segregation of dangerous goods.
