Based on the qualities and properties of the material, dangerous goods are divided into 9 classifications. The TDG Regulations specify these requirements. Typically, the consignor designates the hazard class for a drug. The classification must be made by a qualified individual who possesses the necessary education, experience, and training. The TDG Regulations have classified several chemicals into various classifications. Please refer to the OSH Answers Transportation of Dangerous Goods (TDG) - Classification for further information on how classification functions.
What are each class's primary worries?
For complete information on classes, divisions, and exclusions, always refer to the TDG Regulations. The general description of each class is given in the table below. Examples of Class Hazards Explosives of Class 1 This category is divided into six sections. The substance or item must have the potential to cause a mass explosion, fragment projection, fire hazard, minor blast or projection hazard, ignite or start while in transit, be extremely insensitive with a mass explosion hazard, or be very insensitive with no mass explosion hazard in order to be considered. •Ammonium picrate •Weapons cartridges (with specific characteristics) Black phosphorus •Pyrotechnic elements Gases in Class 2 Flammable gases, non-flammable and non-toxic gases, and toxic gases are the three categories. According to UN 1950, based on the aerosol's characteristics, gases may be conveyed as flammable, nonflammable, or nontoxic aerosols. Nitrogen and propane Dioxide of carbon uncompressed oxygen Refrigerated liquid oxygen, chlorine, and sulfur dioxide flammable liquids in class 3 Substances are classified in this class if it is anticipated that they would be able to catch fire at standard temperatures, based on a liquid's flash point and other characteristics. Gasoline and diesel engines •Methanol Flammable Solids, Substances Prone to Spontaneous Combustion, and Substances That Emit Flammable Gases When Contacted with Water are examples of Class 4 Substances and Products (Water-reactive Substances) Flammable solids, compounds susceptible to spontaneous combustion, and water reactive substances make up Class 4's three subcategories. These chemicals have the potential to ignite fire (via friction), explode when in contact with water, explode even when in contact with oxygen (air), or experience a reaction that will intensify an exothermic process (a reaction that releases heat). For illustration, Class 4.2 The list of chemicals that are prone to spontaneous combustion includes those that catch fire five minutes after coming into contact with air. Safety matches and sulfur •Naphthalene •Activated carbon •Caesium carbide Class 5 substances that oxidize, such as organic peroxides Oxidizing chemicals and organic peroxides make up the two categories. These compounds have the potential to react severely with other substances, burn quickly, burn explosively, be sensitive to impact or friction, or harm the eyes. •Fertilizer with an ammonium nitrate basis Dibenzoyl peroxide with hydrogen peroxide Class 6 Biological and Chemical Agents Toxic chemicals and compounds that cause infections make up the two categories. Class 6 substances are those that, when ingested, inhaled, or in touch with the skin, can result in death, serious injury, or harm to human health. If they have certain features, medical or clinical waste may also be categorized as an infectious substance. The following substances are present: strychnine, arsenic, phenol, chloroform, bacteria, and viruses. Radioactive Materials of Class 7 The items covered by the Packaging and Transport of Nuclear Substances Regulations are considered radioactive materials. •Products containing tritium Corrosive substances of class 8 This class does not have any divisions. If a substance is known to result in skin damage like burns, destruction (thickness), or lesions, it is classified as being in Class 8. Acetate acid Fluoride acid Class 9 Other Products, Materials, or Organisms When a substance appears in column 3 of Schedule 1 of the TDG Regulation or by one of the other inclusions and exclusions specified in the regulations, it is referred to as a Class 9 substance. Substances include things that are dangerous enough to be covered by the TDG laws but that don't fit into any other category. • Solid carbon dioxide (dry ice) • Lithium batteries and cells
Which safety marks apply to each class?
The TDG Regulations specify the mandatory safety marks' size, form, and color. For each class, the following table lists typical safety marks. Please refer to Transport Canada's ""Marks of Safety"" to obtain a list of all mandatory safety markings. Class Typical Safety Mark (s) Explosives of Class 1 The sample displays classes 1.1, 1.2, and 1.3. Gases in Class 2 Examples reveal: flammable gases (Class 2.1), non-flammable and non-toxic gases (Class 2.2), and toxic gases (Class 3) flammable liquids in class 3 An example demonstrates Class 3 Flammable Liquids. Flammable Solids, Substances Prone to Spontaneous Combustion, and Substances That Emit Flammable Gases When Contacted with Water are examples of Class 4 Substances and Products (Water-reactive Substances) Class 4.1 Flammable solids are displayed in the sample. Organic Peroxides and Other Members of Class 5 of Oxidizing Substances Glass 5.1 Oxidizing chemicals, as seen in the sample Toxic and infectious substances of class 6 Class 6.1 Toxic and Class 6.1 Infectious Substances are evident in the samples. Radioactive Materials of Class 7 Sample displays Radioactive materials of class 7, category I, white Corrosive substances of class 8 Sample displays Corrosives of Class 8 Class 9 Other Products, Materials, or Organisms Samples include Class 9 Lithium Batteries and Class 9 Other Products, Substances, or Organisms."""
