Notes to Table 3.2.7.1.:
\r \n(1) The numbers refer to the class and division of dangerous goods as defined in the Transportation of Dangerous Goods Regulations, SOR/2001-286 (TDGR), made under the Transportation of Dangerous Goods Act (Canada).
\r \n(2) The categories and subcategories in the “Workplace Hazardous Materials Information System (WHMIS)” refer to hazardous products classified in Part 7 of the Hazardous Products Regulations, SOR/2015-17, made under the Hazardous Products Act (Canada).

\r \n(4) RESERVED.
\r \n(5) RESERVED.
\r \n(6) 50 kg for nitrocellulose-based products; 10 kg for “strike anywhere” matches.
\r \n(7) “Oxidizing substances” refers to solids or liquids, not gases.
\r \n(8) The TDGR defines “packing group” as “a group in which dangerous goods are included based on the inherent danger of the dangerous goods.” Packing Group I products are more hazardous than Packing Group III products.
\r \n(9) Class C in the WHMIS applies to oxidizing materials. Oxidizers do not usually self-combust but they will feed a fire by supplying oxygen or cause other materials to suddenly ignite. Oxidizers exist in all three states: gas (oxygen, ozone), liquid (nitric acid, perchloric acid solutions) and solid (potassium permanganate, sodium chlorite). Some oxidizers, such as the organic peroxide family, have both combustibility and oxidizing properties, which means they can have strong reactions that can result in an explosion.
\r \nThe exempt amount listed for oxidizing materials in this Table applies to two categories of oxidizers based on the TDGR classification: oxidizing substances and organic peroxides. Since the WHMIS does not have a corresponding classification for these two categories of oxidizers, it was decided that the exempt amount applicable to Class C should be the more stringent one, thus reducing the potential that large quantities of oxidizing materials with combustibility properties will be stored without implementing the applicable safety measures in Subsection 3.2.7.
\r \n(10) Small quantity exemptions may be determined by other authorities such as the TDGR, the WHMIS and environmental protection legislation.
\r \nIgnition sources
\r \n3.2.7.2. (1) Heating appliances shall not be permitted in a fire compartment used for the storage of dangerous goods classified as flammable gases, flammable liquids, flammable solids, pyrophoric materials, water-reactive substances, oxidizers or organic peroxides, unless they are installed in a manner that will not create a fire or explosion hazard.
\r \n(2) Smoking shall not be permitted within a fire compartment used for the storage of dangerous goods and signs shall be posted in conformance with Article 2.4.3.2.
\r \n(3) Except as provided in Sections 3.4. and 5.17, open flames and spark-producing devices shall not be used in an area where dangerous goods are stored.
\r \nAmbient conditions
\r \n3.2.7.3. (1) Rooms or parts of buildings used for the storage of dangerous goods
\r \n(a) shall be dry and cool, and
\r \n(b) where the products being stored are capable of releasing flammable or toxic gases or vapours under normal ambient conditions, shall be provided with a ventilation system to exhaust such gases or vapours outdoors to an area where they will not return to the building.

\r \n(2) Storage heights for a protected storage area stated in Table 3.2.7.5. are permitted to be exceeded provided the dangerous goods are stored on racks or shelves.
\r \n(3) When a storage area is required by this Article to be protected, it shall be sprinklered or protected with a special fire suppression system, in conformance with NFPA 13, “Standard for the Installation of Sprinkler Systems”, Part 2 and good engineering practice with respect to specific dangerous goods.
\r \n(4) Stored dangerous goods other than compressed gases shall be kept not less than 100 mm above the floor level.
