Hey there! As a supplier of Iso Tank Containers, I often get asked about the markings on these bad boys. You know, those little symbols and numbers that seem like some sort of secret code? Well, today I'm gonna break it down for you and explain what each marking means.
First off, let's talk about why these markings are so important. Iso Tank Containers are used to transport all sorts of dangerous and non - dangerous goods across the globe. The markings on them are like a safety manual in visual form. They tell everyone from the people loading the container to the truck drivers and port workers what's inside, how to handle it, and what precautions to take.
UN Number
One of the most crucial markings you'll see on an Iso Tank Container is the UN number. The "UN" stands for the United Nations. Each UN number corresponds to a specific hazardous substance. For example, UN 1012 represents propane. This number helps emergency responders quickly identify the substance in case of an accident. If there's a spill or a fire, they can look at the UN number and immediately know what kind of chemicals they're dealing with and how to respond safely.
Product Name
Right next to the UN number, you'll usually find the product name. It's pretty self - explanatory. If the UN number is 1012, the product name will say "Propane". This double - verification is important because sometimes, different substances can have similar - looking UN numbers, and having the product name there makes it crystal clear what's inside the tank.
Hazard Class Label
Iso Tank Containers also have hazard class labels. These are diamond - shaped signs that indicate the type of hazard the substance poses. There are nine main hazard classes, including flammable liquids (Class 3), toxic substances (Class 6), and corrosive materials (Class 8). For instance, if you see a red diamond with a flame symbol, it means the contents are flammable. This label is a big red flag (literally) for anyone handling the container, reminding them to take extra precautions.
Tare Weight and Gross Weight
Another important set of markings are the tare weight and the gross weight. The tare weight is the weight of the empty container. The gross weight is the weight of the container plus its contents. These numbers are essential for transportation. Truck drivers need to know the gross weight to make sure they're not overloading their vehicles, which could lead to accidents or fines. And at ports, the weights are used for shipping calculations and to ensure that the container can be safely loaded onto ships.
Maximum Allowable Working Pressure (MAWP)
The MAWP marking shows the maximum pressure that the tank can safely handle. It's measured in pounds per square inch (psi) or bar. This is super important because if the pressure inside the tank exceeds the MAWP, it could lead to a rupture or an explosion. Operators need to monitor the pressure constantly and make sure it stays within the safe range.
Serial Number
Each Iso Tank Container has a unique serial number. This number is like the container's fingerprint. It's used for tracking and identification purposes. If there are any issues with the container, such as a manufacturing defect or a maintenance problem, the serial number can be used to look up its history and find out when it was made, where it's been, and what kind of servicing it's had.
Year of Manufacture
The year of manufacture is also marked on the container. This information helps determine the container's age. As containers get older, they may require more frequent inspections and maintenance. It also gives an idea of the container's design and construction standards, as manufacturing techniques and safety requirements have evolved over the years.
Inspection and Testing Dates
Iso Tank Containers need to be regularly inspected and tested to ensure they're safe for use. The markings will show the dates of the last inspection and the next due date. This is a key safety feature. If a container hasn't been inspected on time, it shouldn't be used for transportation until it passes the required tests.
Compatibility Markings
Some containers have compatibility markings. These indicate what substances the container can safely hold. For example, a container might be marked as suitable for transporting certain types of acids but not others. This is important because using a container that's not compatible with the substance can lead to corrosion, leaks, and other safety hazards.
