One of the class 4 safety marks has a blue background, do you know what that means and what kind of danger does the color blue indicate? This means the product is Dangerous when wet (4.3). Please keep in mind that Class 4 isn’t the only one separated into different types of hazards, called Divisions. Classes 1, 2, 5 and 6 also have Division.
Remember that if a product has more than one type of hazard, it may belong to more than one dangerous goods class. For example, methanol is a flammable liquid but it’s also toxic. The primary class – the greatest risk – is listed first, with the subsidiary class in brackets.
You must not forget that the type of danger is always shown by the class number. Often the degree of danger is shown by a packing group number – one, two or three – in Roman numerals: Packing group “I” means great danger, packing group “II” means moderate danger while Packing group “III” means minor danger.
When dealing with TDG, it is always important to remember the difference between primary and subsidiary classes.
At Pipeworx, we have various products that fall under hat TDG regulation, many of our operator transport a large amount of diesel, gasoline, propane and other products used for welding. All the available shipping names are listed in the TDG Regulations and it’s up to the shipper to choose the correct one.
It is not an easy job, because there are hundreds of thousands of chemical compounds and millions of trade names. However, the TDG list limits the choices when it comes to the shipping name – the one that’s used to describe the product on the container and on the shipping document.
