How Many Classes Of Hazardous Materials Are There

How Many Classes Of Hazardous Materials Are There – If your organization works with dangerous goods, your operational compliance is critical to the safety of your employees, your property, the environment and your community. There are 9 classes of dangerous goods in the Australian Dangerous Goods Code. Dangerous goods are classified according to their physical and chemical properties. Categories range from Class 1 explosives to various Class 9 dangerous goods. Dangerous Goods Australia explains: “Substances (including mixtures and solutions) and articles subject to this code are classified based on the hazard or greatest hazard they pose assigned to one of nine classes. Some of these Dangerous Goods Classes are specially subdivided sections. For more information on the classes and subdivisions of dangerous goods in Australia read on Classes and Divisions of Dangerous Goods Class 1: Explosives Section 1.1: Substances and Articles Presenting a Risk of a massive explosion Section 1.2: Substances and articles presenting a risk of explosion but no risk of mass explosion: Substances and articles presenting no significant risk Part 1.5: Very insensitive substances presenting a risk of mass explosion Part 1.6: Very insensitive Items that ke at risk of mass explosion Class 2: Gas Part 2.1: Combustible Gas Division No. 2.2: Non-toxic Gas Section 2.3: Toxic Gas Class 3: Flammable Liquids There is no subsection for Class 3 Flammable Liquids. Class 4: Flammable Solids are spontaneously flammable Substances that emit gases are spontaneously flammable Contact with water Section 4.1: Solid substances Flammable mist, self-reactive substances and solid sensitizing explosives. Peroxides Section 5.1: Oxidizing substances Section 5.2: Organic peroxides Class 6: Toxic and infectious substances Section 6.1: Toxic substances Section 6.2: Infectious substances Class 7: Radioactive substances No subsection for radioactive substances Class 7. Class 8: Corrosive No subsection for Class 8 Corrosive. Class 9: Other Dangerous Goods There is no subsection for Class 9 Other Dangerous Goods. To better understand the classes or subdivisions of workplace hazardous materials and the risks they pose, let’s look at each class in more detail. Here we list the definition of each category of dangerous goods according to the relevant Australian standards: Dangerous Goods Classification Chart which defines each class of dangerous goods. 1: Explosives As stated in Section of the Australian Dangerous Goods Code, Class 1 dangerous goods can be defined as follows: (a) Explosives (materials which are not explosive but which are capable of forming gas, dust and vapor explosions. Not included in Class 1), except those too dangerous to transport or where the primary hazard is appropriate for another class. and (b) explosives, except for devices containing explosives in such quantity or in such an accidental or accidental manner, or the detonation of which during carriage does not cause any external effect on the device, including explosion, fire, smoke, heat or strong Noise . Noise; and (c) Substances and articles not listed under (a) and (b) which are manufactured with a view to achieving a practical, explosive or oxidizing effect. Explosive Class 2: Gas According to Section of the Australian Dangerous Goods Code, a gas is any substance which: has a vapor pressure greater than 300 kPa at a temperature of 50°C. Or it is a complete gas at 20°C at a standard pressure of 101.3 kPa. (a) Section 2.1 Combustible gases – Combustible gases at a standard pressure of 20 °C and 101.3 kPa: (i) in a mixture of 13% by volume or less with air; or (ii) has an air flammability range of at least 12%, regardless of the lower flammability limit. (b) Section 2.2 Non-flammable, non-toxic gases – gases which: (1) displace – gases which normally liquify or displace oxygen in the atmosphere; or (ii) oxidizing – a gas capable of causing or assisting the combustion of substances other than air, generally by supplying oxygen. or (iii) not contained in any other section. (c) Section 2.3 Toxic Gases – Gases which: (1) are known to be highly toxic or corrosive to humans and thus present a health hazard; or (ii) considered toxic or corrosive to humans because it has an LC50 (as defined in equal to or less than 5000 milliliters per cubic meter (ppm). Class 3: Flammable liquids Flammable liquids are substances that burn in an ignition source. It is used for high-power equipment such as vehicles, generators, outdoor power equipment, etc. The Australian Dangerous Goods Code defines a Class 3 flammable liquid as follows: A flammable liquid is a liquid or mixture of liquids or liquids containing dissolved or suspended solids (e.g. their hazardous ones) that produces flammable vapor temperatures. A maximum temperature of 60 °C, closed cup test, or a maximum temperature of 65.6 °C, open cup test, is commonly referred to as the flash point. This class also includes: (a) liquids offered for carriage at temperatures at or above the flash point; and (b) Substances carried or offered for carriage in the liquid state at elevated temperatures and producing flammable vapor temperatures at or below the maximum carriage temperature. When working with flammable liquids, it is important to remember that the flash point of a substance can vary depending on the presence of impurities. Flammable Liquids Class 4: Flammable Solids Flammable solids are substances which are subject to spontaneous combustion and/or substances which, in contact with water, emit flammable gases. When combustible solids burn, they often emit toxic gases. Class 4 dangerous goods are divided into three parts as follows: (a) Part 4.1 Combustible solids are solids which are flammable under conditions of transport or which through friction may cause or contribute to fire. A self-reactive substance that undergoes a strong exothermic reaction. A solid desensitizing explosive that can detonate if not diluted sufficiently. (b) Section 4.2 A spontaneously combustible substance is a substance which, under normal conditions of transport, will self-heat or become heated on contact with air and then burn. (c) Section 4.3 Substances which, in contact with water, emit flammable gases Substances which, on interaction with water, may spontaneously ignite or emit flammable gases in dangerous quantities. Class 5: Oxidizing substances The Australian Dangerous Goods Code defines Class 5 dangerous goods as follows: (a) Section 5.1 Oxidizing substances are substances which, while not necessarily being flammable per se, are generally capable of producing a to cause burns. be or help him. Other material such as such material may be included in the article. (b) Section 5.2 Organic peroxide An organic substance that has a divalent structure -0-0- and can be considered a derivative of hydrogen peroxide where one or both hydrogen atoms have been replaced by an organic radical. Organic peroxides are thermally unstable substances that can undergo exothermic self-accelerating decomposition. In addition, it may exhibit one or more of the following properties: (i) undergoes explosive decomposition; (b) burns quickly. (iii) sensitive to shock or friction; (iv) dangerous reactions with other substances; (v) cause eye damage. Class 6: Class 6 toxic and infectious substances are divided into two parts. These definitions for each subsection under the ADG Code are listed below: (a) Section 6.1 Toxic Substances These substances can cause death or serious injury or damage to health if swallowed or inhaled, or if they come into contact with skin. (b) Section 6.2 Infectious substances These are substances which are known or can reasonably be expected to contain infectious agents. Pathogens are defined as microorganisms (including bacteria, viruses, rickettsia, parasites, fungi) and other agents such as prions that can cause disease in humans or animals. Toxic Substances Class 7: Radioactive Substances According to Section of the ADG Code, radioactive material is defined as: any material containing radionuclides where both the concentration of activity and the amount of activity in the cargo exceed the levels specified by the Australian Standard, AUST ST. For Class 7) For more detailed information on radioactive material, consult your supplier, the appropriate safety data sheet or a dangerous goods professional. Class 8: Corrosive Substances The Australian Dangerous Goods Act defines a corrosive substance as follows: A Class 8 substance (a corrosive substance) is a substance which by chemical action causes serious injury upon contact with living tissue or causes serious injury if spilled. Materially damage or destroy goods, materials or other items. Corrosive substances Class 9: Miscellaneous dangerous substances and articles under the Australian Dangerous Goods Code,
