Part 1 - Special Cases

Dangerous Goods



Question

Part 1, subsection 5 of section 1.17 on limited quantities, refers to documentation of limited quantities exceeding 500 kg gross mass. This question has to do with the section refereing to: « by one consignor to one destination is greater than 500 kg ». If there is a trailer with multiple destinations and each destination has a separate bill of lading, does the 500 kg apply to the complete trailer or to each destination?

Answer

Subsection 1.17(5) is intended to apply to a consignor who offers for transport to one destination an accumulation of limited quantities with a gross mass exceeding 500 kg. In the scenario above there is one consignor but many destinations and each destination is receiving an accumulation of limited quantities that exceeds 500 kg and these accumulations are in one road vehicle. Consequently, each destination with an accumulation exceeding 500 kg would require a document completed in accordance with subsection 1.17(5).



Question

Cargo truck tanks are sometimes furnished with additional small tanks, permanently attached to the truck frame and filled with an ammonia solution (UN 2672). Such a tank is rigidly plumbed to the main tank and its purpose is to scrub hydrogen sulphide (H2S) from sour crude oil during the main tank loading. Can the ammonia solution in the scrubber tank be exempted as per section 1.27 taking into account that the ammonia is only used to safeguard the fill-in operation and protect the environment?

Answer

The ammonia contained in the tank (scrubber) is necessary for the safe operation of the means of containment and is necessary for the safety of the people loading and unloading the crude oil. The ammonia and the means of containment used to contain it are therefore exempt under section 1.27. The associated piping system which is mounted to the crude oil tank and containing the crude oil vapours would be subject however to the design and construction requirements of CSA B620 and to the periodic inspection and test requirements of Clause 8.



Question

Does section 1.25 exemption apply to all transportation within a facility?

Answer

When a segment of a transportation event is due to occur or has occurred outside the boundaries of a facility, the whole transportation event must be done in compliance with the Regulations, including those segments taking place within a facility.



Question

Can a police officer on travel status and handling or transporting ammunition or ammunition loaded in a firearm be exempt from the TDG Regulations, except Part 6 on Training, according to section 12.4(2) of the TDGR?

Answer

Yes, a police officer is considered on duty while he is on travel status.



Question

What is the extent of section 1.26?

Answer

The Emergency Response Exemption was intended to apply to vehicles dedicated solely to emergency response. It does not apply to vehicles or equipment that might be used in emergency response but are also used for different purposes. Therefore, dangerous goods onboard a vehicle not exclusively used for emergencies are not exempt.



Question

When using a dangerous good (such as ethanol or formaldehyde) to preserve a biological sample (such as a frog or an animal organ) during transportation, should the dangerous good be exempt from the Regulations?

Answer

No, sections 1.19.1 and 1.19.2 do not apply to this situation. They apply only to samples that are believed to be dangerous goods. In this case, the sample is not a dangerous good, it is the substance used to preserve the sample that is a dangerous good.



Question

Can a fuel pump transported aboard an aircraft be exempt from the TDG Regulations, in accordance with section 1.27 of the TDG Regulations?

Answer

Since a fuel pump is not necessary for the safety of the individuals on the aircraft, and is not required for the operation or the safety of the aircraft, section 1.27 does not apply. The fact that the fuel pump would not be used during the operation of the aircraft is another reason why 1.27 does not apply.



Question

What does subparagraph 1.35(a)(ii) mean regarding the placards or labels displayed on a means of containment that is visible from outside of the road vehicle?

Answer

The provision states that where placards cannot be displayed on all four sides of the tank because of the tank configuration (for example if only two or three of the sides are visible from outside the vehicle), placards are required only for those sides that are visible.
