What is an exemption in the DGR, and can you name two common types?

• A. A provision that allows certain dangerous goods to be transported with simplified or different requirements; common types are Limited Quantities (LQ) and Excepted Quantities.
• B. A requirement to always apply the full DGR rules.
• C. A type of packaging material.
• D. An endorsement by the shipper.

Answer: (A)

Exemptions in the Dangerous Goods Regulations let certain shipments move under simplified or alternative rules because the overall risk is lower. Two common types are Limited Quantities and Excepted Quantities.

Limited Quantities allow dangerous goods to be shipped in small amounts per package with reduced packaging, labeling, and paperwork requirements. There are specific limits on how much can be in each package and how many packages can be shipped, but the goal is to enable convenient transport of low-risk quantities while keeping safety in check. This is often used for consumer items or samples that contain hazardous materials but in small amounts.

Excepted Quantities cover extremely small amounts of dangerous goods that pose minimal risk. The per-package quantities are tiny, and many standard dangerous goods requirements (like full documentation or extensive labeling) are not needed. This exemption is meant for very limited, low-hazard cases.

In both cases, the idea is to balance practical transport with safety by recognizing when the risk is sufficiently low to justify lighter requirements.
