Shipping papers may alert you to the presence of hazardous materials through a variety of required entries, including those listed below. Use of human senses of smell or taste should not be used to determine the presence of a hazardous material Hazardous occupancies and problem locations should be identified and evaluated during a pre- incident planning. DOT Placarding System requires vehicle carrying over 1001 pounds of corrosive to display ________ placard. A type of gas that can be extremely toxic and is considered by the DOT to be a hazardous material is a(n): Definitions of DOT hazard classes and divisions.(Top of the ERG Guide Pages) Know the different hazard class they are listed in the ERG. Know the number of classes and materials represented by the division Class 1 (Explosives) An explosive is any substance or article, including a device, that is designed to function by Explosion (i.e., an extremely rapid release of gas and heat) or that, by chemical reaction within Itself, is able to function in a similar manner even if not designed to function by explosion. Explosives in Class 1 are divided into six divisions. Each division will have a letter designation. Class 2 (Gases) Class 3 (Flammable/Combustible Liquid) - Flammable liquid is any liquid having a flash point of not more than 60.5ºC (141ºF). Examples of Class 3 liquids include acetone, amyl acetate, gasoline, methyl alcohol, and toluene. Combustible liquid is any liquid that does not meet the definition of any other hazard class and has a flash point above 60ºC (140ºF) and below 93ºC (200ºF). Flammable liquids with a flash point above 38ºC (100ºF) can be reclassified as a combustible liquid. Examples of combustible liquids include mineral oil, peanut oil, and No. 6 fuel oil. Class 4 (Flammable Solids) Class 5 (Oxidizers and Organic Peroxides) - Division 5.1 (oxidizer) - Division 5.2 (organic peroxide) materials are assigned to one of seven types Class 6 (Poisonous Materials) Class 7 (Radioactive Materials) - Radioactive material is any material having a specific activity greater than 0.002 microcuries per gram (mCig). Examples of Class 7 materials include cobalt, uranium hexafluoride, and depleted uranium found in aircraft (as counter balances) and munitions. Class 8 (Corrosive Materials) - Corrosive material is a liquid or solid that causes visible destruction or irreversible alterations in human skin tissue at the site of contact or a liquid that has a severe corrosion rate on steel or aluminum. Examples of Class 8 materials include nitric acid, phosphorus trichloride, sodium hydroxide, and sulfuric acid. Class 9 (Miscellaneous Hazardous Materials) - Miscellaneous hazardous material is a material that presents a hazard during transport, but that is not included in another hazard class, including the following: (a) Any material that has an anesthetic, noxious, or other similar property that could cause extreme annoyance or discomfort to a flight crew member so as to prevent the correct performance of assigned duties. (b) Any material that is not included in any other hazard class, but is subject to the DOT requirements (a hazardous substance or a hazardous waste). Examples of Class 9 materials include adipic acid, hazardous substances (e.g., PCBs), and molten sulfur.
