In addition, they must also have the proof of classification that may be required by <a href=\"https:\/\/tc.canada.ca\" target=\"_blank\" rel=\"noopener noreferrer\">Transport Canada<\/a><\/span><span style=\"font-weight: 400\">\u00a0as per <\/span><a href=\"https:\/\/www.thecompliancecenter.com\/ca\/product\/bk-clrome\"><span style=\"font-weight: 400\">section 2.2.1 of the TDG<\/span><\/a><span style=\"font-weight: 400\">.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Just to refresh your memory, the classification standards for dangerous goods in theory are those set by the UN Manual of Tests and Criteria.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Though this is true, I would like to demonstrate that there are a few exceptions.<\/span><\/p>\n<p><span style=\"font-weight: 400\">To demonstrate one of these exceptions, let&#8217;s discuss number <a href=\"https:\/\/www.thecompliancecenter.com\/ca\/selector-product-search\/zero\/1093\/zero\/\">UN1093<\/a>, STABILIZED ACRYLONITRILE, primary class 3 and subsidiary class 6.1, packing group I.<\/span><\/p>\n<p><span style=\"font-weight: 400\">As usual, we must turn to Schedule 1 of the TDG to find the product or we can also go to the alphabetical index in Schedule 3.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Now let&#8217;s establish the ground rules needed to check Schedule 1 for this product.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The DG contains the special provision 155, which states that if the product is to be transported stabilized by temperature control, it must be transported in accordance with section 7.1.6 of the UN Recommendations.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">We cannot use the limited or excepted quantity exemptions because a &#8221;0&#8221; appears in columns 6a and 6b.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Column 7 displays the number 1,000 which means that if the container contains more than 1,000 liters, an emergency\u00a0 response assistance plan (ERAP) must be prepared and approved by Transport Canada.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">For the purposes of this scenario, the containers did not contain quantities that would require an ERAP.<\/span><\/p>\n<p><span style=\"font-weight: 400\">To establish the classification, everyone knows about the Safety Data Sheets (SDS) and we usually use this document to get the specifications of our product.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Now, I consulted the SDS to determine the classification of the product in question and it showed a flash point and boiling point that classified the product as a packing group II flammable liquid. This information is found in section 9 of the SDS.<\/span><\/p>\n<p><span style=\"font-weight: 400\">After this, I checked section 11 of the SDS to determine if the product was toxic and yes, the product met the characteristics of class 6.1 of packaging group II.<\/span><\/p>\n<p><span style=\"font-weight: 400\">This is where my questions began, because in Schedule 1 of the TDG, the product is listed as a DG of packing group I, but the product characteristics according to the SDS show those of packing group II instead.<\/span><\/p>\n<p><span style=\"font-weight: 400\">I then began my research to find out why this situation was occurring and more importantly to find the answer.<\/span><\/p>\n<p><span style=\"font-weight: 400\">I managed to find out why and it is related to the fact that the TDG is inspired by and adopts the UN classification criteria, and in the UN recommendations the product UN1093 is indeed classified as UN1093, STABILIZED ACRYLONITRILE, primary class 3 and subsidiary class 6.1, of packing group I.<\/span><\/p>\n<p><span style=\"font-weight: 400\">This is despite the fact that the product does not meet the characteristics, however the UN does classify it as such and our Canadian TDG regulations by default display the product in the same way as the UN.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">This is the reason why the classification of my product did not match the characteristics of part 2 of our TDG.<\/span><\/p>\n<p><span style=\"font-weight: 400\">In conclusion, it is important to never forget that this scenario can happen occasionally and to remember to do the proper research in order to find the answers.<\/span><\/p>\n<p><span style=\"font-weight: 400\">At ICC we are able to assist if you ever find yourself in such a
