Dangerous Goods Classes & Regulations - Gases

An in-depth look at one of the nine classes of dangerous & hazardous goods - Class 2: Gases

Shipping Class 2 Dangerous Goods

There are a total of nine dangerous/hazardous goods classes that are used day in and day out within the logistics sector. Each item/product/good that when transported are a risk to safety, health or the environment needs to be categorised into one of those classes.

On the Tudor Website you will find information in respect of each class of the nine dangerous goods categories. If you want a full overview of what you need to consider when shipping dangerous goods, be sure to check out our previous blog here.


What is a Class 2 Dangerous Good?

Class 2 of the nine dangerous goods is gases. This covers compressed gases, liquefied gases, dissolved gases, refrigerated liquefied gases, mixtures of gases and aerosol dispensers/articles containing gas. Gases are generally pressurised and it is this reason that makes them hazardous when transported by air, sea or road. If the pressure is suddenly released it can pose a serious threat. Gases can also be extremely flammable, whilst others can be toxic or corrosive to humans.

As you would expect, the transportation of gases is regulated and only trained personnel are able to pick up and deliver this type of hazardous cargo. In addition, a dangerous goods note must be completed by an individual who has carried out specific hazardous cargo training.


Class 2: Gases – Sub Divisions:

Gases can cause dire physical damage, for example; If a cylinder valve gets damaged, the escaping gas could be concentrated into a powerful jet making the cylinder take off like a rocket. Although a lot of gases can cause physical injury of this sort, fatal chemical damage can also be inflicted and therefore the class is split into sub-divisions. There are three sub-divisions of class 2 hazardous cargo which are as follows:

Division 2.1: Flammable Gases

Division 2.2: Non-Flammable / Non-Toxic Gases

Division 2.3: Toxic Gases
