- What is the 150 kg Gross Mass Exemption?
- Subsection 1.15 of the Transportation of Dangerous Goods Regulations (as outlined by Transport Canada) will exempt a person from most parts of the Regulations if they meet all exemption conditions.
- How do I use the exemption?
- Most people use this exemption without even knowing it; it is used when you bring small amounts of dangerous goods such as gasoline, propane, paint, etc, home from the place of purchase.
- This exemption can only be used if the dangerous goods are available to the general public, and the dangerous goods must be transported by the user/purchaser or by a retailer to or from a user/purchaser. Carriers, who are not the retailer, cannot use this exemption.
- Since you may not transport all dangerous goods under this exemption, it is important to check subsection 1.15(2) first. It will list the products that CANNOT be transported under this exemption.
- Key points to remember:
- The total mass of all dangerous goods (i.e. oxygen, propane, gasoline, etc) must not be greater that 150 kg; gross mass includes the weight of the container and all of its contents.
- The dangerous goods must be packed in containers that weigh 30 kg or less (except for gases – see below).
- The dangerous goods must be available to the general public and transported by the user/purchaser or by a retailer to or from a user/purchaser.
- The containers must be designed to not leak under normal conditions of transport.
- You must not combine this exemption with:
- exemptions in sections 1.16, 1.21 and 1.22, or
- a shipment of dangerous goods that requires a shipping document (i.e. a fully regulated shipment).
- When using the 150 kg Gross Mass Exemptions for Class 2 Gases, there are two important things to note:
- If you are transporting a gas such as propane or oxygen, the cylinder must be certified for use in Canada and marked with the letters "TC". Cylinders certified for use in the United States will be marked with the letters "DOT". As a general rule, you may not use cylinders only marked with the letters "DOT" in Canada. You will find certain exemptions to this rule in section 5.10(2)(c). It is possible that a cylinder can be certified for use in both Canada and the United States. If this is the case, the cylinder will be marked with the letters "DOT/TC".
- Flammable gases, such as propane or acetylene, are limited to a cylinder size of 46L.
- What if I don't meet the conditions for the exemption?
- As with any exemption, if you cannot meet one of the specified conditions, then the exemption does not apply and you must comply with the entire Transportation of Dangerous Goods Regulations. This means you might need a shipping document, labeling, placarding, training, a certified container or package, etc.
