DG Classes, Safety Marks and Associated Hazards

1 1 DG Classes, Safety Marks and Associated Hazards Knowledge and Skills Needed for Competency Element 1 The information included in this document is to help you prepare for the evaluation of competency element 1. After studying this section you should: be able to identify the nine classes of dangerous goods be able to identify their safety marks (placards or labels) be able to identify the hazards associated with the goods in each class be able to find information about placards and labels be able to explain what to do when you find an incorrect safety mark be able to explain when to fix and remove placards Introduction It is important to be able to correctly identify dangerous goods because the classification is the first and most important step of the TDG regulation. Without the proper shipping name and classification you will not be able to handle, label or ship the good in Canada. If you do not correctly identify or comply with TDG regulations you may face legal charges. Maximum penalties in the federal regulations include fines of up to $100,000 and up to two years in jail. In addition, it is important to know about shipping and handling dangerous goods to have a safe work environment.

2 2 A. Identifying the Nine Classes of Dangerous Goods and their Associated Hazards Worked Example The worked example below is to show you how to find the general category and associated hazards of each class of DG. Safety Mark (Placard or Label) General Category General category: Explosives Specific : Class 1 Hazards 1.1 Mass explosion hazard Ex: Charges, Demolition UN 0048 class How to find the General Category To find the general category follow the steps below: 1. There are 9 classes of dangerous goods. Certain classes are divided into subgroups called divisions. These indicate less significant differences between goods in one class. The division will be indicated by adding a decimal point and the division number after the class example class 1.1 (see table above). 2. If you are looking for the classification and hazards of the 9 classes go to the Transport Canada web site schedule 1: 3. To find the classification of your product you need the Shipping Name or UN number: for example UN Type OO48 in the box after UN and click on search 4. The computer will show you: a. UN0048 in the first column b. the shipping name and description charges, demolition in the second column c. the classification 1.1 in the third column.

3 3 2. How to find the Associated Hazards To find the associated hazards follow the steps below: 1. Each class or division is assigned a hazard symbol. This will be used on labels for the packages and placards for vehicles and freight containers. 2. If you are looking for associated hazards for the 9 classes go to the Transport Canada web site schedule 1 which lists all products by UN number: 3. Then go to Part 2 from the menu on the left side of the screen and enter. You will be able to identify the hazard in each class for the regulations in Canada. Scroll down the page and use the information in the General and Division sections of each of the nine classes to complete the table on the next page. 3. Evaluation Preparation Work Using the procedures explained on the previous pages complete the table in the evaluation preparation document on the website. You should know the general category and associated hazards of the remaining 8 classes of DG. You will complete this table and it to the content specialist before the evaluation.

4 4 B. Finding Information about Safety Marks: Placards or Labels It is almost impossible to memorize every placard and what every safety mark means. However, it is important to know where you can find information about them so that you can transport goods safely. The shipper will determine which dangerous goods safety marks are to be displayed on the product. 1. Information about placards and labels can be found at the following website: 1. If you are looking for placards to use on trailers or safety marks to use on packages, you must have the UN 4 digit number or Shipping Name and go to Transport Canada web site schedule 1: 2. After you have found the class of your good from column 3 of schedule 1 go to PART 4 from the menu on the left side of the screen and enter. 3. Go to Requirements for Dangerous Goods Safety Marks. This will identify the safety marks and how to show them on trucks or boxes in Canada 4. If you are looking for placards on trucks or container (large means of containment): a. go to section 4.3. This will advise you when to apply the placard on large mean of containment over 450 kg or litters. (truck or container) b. Then go to section 4.15 and refer to table SOR/ Column 1: This lets you identify the type of goods you will be shipping: single goods, mixed goods Column 2: This identifies what you must do: the type of placard or placards you must use Column 3: This identifies if you need to show the UN number c. Once you have identified the placard(s) that you need to use refer to the appendix at the end of part 4 to see which placard to use 5. If you are looking for labels on the box (small means of containment): a. Go to section 4.10 to see the labelling requirements. Then use the process above to find the label needed using the appendix at the end of section 4.

5 5 Example You need to ship 40 boxes of demolition charges by truck. Each box weighs 30 Kg. 1. Using schedule 1 search for the class and UN number, using the shipping name: charges, demolition. 2. This will give you the information: a. UN number (column 1): UN0048 b. Class (column 3): 1.1D 3. Total weight = 40 boxes X 30 Kg = 1,200 Kg 4. 1,200 Kg is over 450 Kg. You will need to use a placard for the truck 5. Using part 4, section 4.15, table SOR/ a. you can identify in column one that you need to ship a single good that has an ERAP (see row 2 of the table) b. Column 2 of the table states that you must show the primary placard c. Column 3 of the table shows that you must show the UN number 6. This is also true for the label on each box of demolition charges 7. Below is what placards and labels you should use Placard for Truck Label for Boxes + Charges, Demolition UN 0048

6 6 2. Documentation on TDG regulation can also be obtained from from Transport Canada web site or buying from Government of Canada publications: Bureau de communications Canada Ottawa (Ontario) K1A 0S9 Tel.: or Fax: or C. Incorrect Placards or Labels If you find an incorrect placard it is important to know what your responsibilities are and what you should do. 1. Shipper s Responsibilities The shipper responsibilities are classified, packed, identified, labelled and do the document for the good moving accordingly to clear language regulation in Canada but if there is discrepancy between label, classification and document than check with the manufactory Material Safety Data Sheet and do not ship the good until discrepancy fixed or call manufactory. (See Transport Canada website, Part 4, section 4.4) 2. Carrier s Responsibilities If the carrier finds a discrepancy between the document and the label on the package at the shipper s door, the driver should not take the goods. If the good is in transit, the carrier will make sure that placards are on the trailer. If they are lost in transit, the carrier will replace them. If the carrier finds a discrepancy at the carrier terminal then the carrier will not move the good until the discrepancy is fixed by a supervisor calling the shipper. (See Transport Canada website, Part 4, section 4.5) 3. Consignee s Responsibilities The receiver off-loads goods safely from trailer then removes placard. If there is a discrepancy with labels then call the shipper immediately.

7 7 D. Fixing and Removing Placards The regulations for fixing and removing placards are listed below: 1. Fixing Placards As per Clear Language Regulation part 4.3: A person must not load or pack dangerous goods into a large means of containment for transport unless, immediately before the loading or packing, the large means of containment displays the dangerous goods safety marks that will be required when the loading or packing is complete. 2. Removing Placards As per Clear Language regulation part 4.3: A person must finish unloading the trailer before removing the safety placard on the outside of the trailer.
