These substances may explosively decompose, burn rapidly, be sensitive to impact or friction, react dangerously with other substances, or cause damage to the eyes.

Dangerous goods are classified into 9 classes, based on the substance’s characteristics and properties. These criteria are outlined in the TDG Regulations.

The following table shows common safety marks for each class. To view all the required safety marks, please see the “Marks of Safety” from Transport Canada.

The purpose of the Transportation of Dangerous Goods (TDG) Act and Regulations is to promote public safety when dangerous goods are being handled, offered for transport or transported by road, rail, air, or water (marine). TDG also establishes safety requirements.

Aerosols under UN 1950, AEROSOLS may be transported as flammable or non-flammable or non-toxic gases, depending on the properties of the aerosol.

Class 9 dangerous goodsshipping requirements

Substances include those that present a danger sufficient to be included in the TDG regulations, but which cannot be assigned to any other class.

Assigning a substance into a hazard class is usually done by the consignor. The person deciding the classification must be competent, meaning they have the education, training, and experience required for the task. Some substances have been assigned classes in the TDG Regulations.

Always consult the TDG Regulations for full details on classes, divisions, and exemptions. This table provides a general overview of each class.

These substances may cause fire (through friction), become explosive when in contact with water, become explosive even with contact with oxygen (air), or undergo a reaction that will result in a stronger exothermic reaction (a reaction that releases heat). For example, Class 4.2 Substances liable to spontaneous combustion includes substances that will ignite within 5 minutes of coming in to contact with air.

Substances are considered Class 9 when they are listed in column 3 of Schedule 1 in the TDG Regulation, or by other inclusions and exclusions as defined in the regulations.
