Finally, also based on the material classification, strict guidelines are furnished for proper labeling/marking of packages of hazardous materials offered for transport, and for placarding of transport vehicles. Based on the classification of the material, the DOT is also responsible for determining the appropriate packaging materials for shipping or transport. These materials are placed in one of nine categories, based on their chemical and physical properties. The DOT has broad authority to regulate hazardous materials that are in transport, including the discretion to determine which materials shall be classified as “hazardous”. Examples: hypodermic needles, human and animal waste. These types of materials often come from hospitals. They consist of materials infected with some type of germ, bacteria, or virus that could cause disease in humans or animals. These materials are also toxic wastes, but are in a separate category. People and animals exposed to these types of materials can develop severe health problems. Most of these materials are produced at nuclear power plants and by research facilities.Ĭonsist of poisonous chemicals.
Include materials with both high and low radioactivity that can lead to dangerous side effects for thousands of years. Examples: old weapons and ammunition, sodium metal, stannic chloride.
Examples: paint removers, the chemical Benzene.Ĭan explode or release deadly fumes by mixing with water or reacting to heat or pressure. This causes a risk of explosion and the spreading of toxic gas over an area, as well as fire and smoke. Present a fire hazard because they are flammable at relatively low temperatures. Because they can eat through the containers they are carried in, they are of special concern during transportation. Hazardous Material can be:Īre strong enough to eat away at steel drums or human skin. The substance can be identified from placards, labels or markings on the transporters. Some Hazardous Materials exist beneath the surface of the ground and have an oil or foam-like appearance. Some can be detected because they cause physical reactions such as watering eyes or nausea. Many hazardous materials (hazmat) do not have a taste or an odor. Hazardous materials (hazmat) are any material that has properties that may result in risk or injury to health and/or destruction of life or facilities.
