Understanding Dangerous Goods
Dangerous goods, also known as hazardous materials, are substances that pose a risk to health, safety, property, or the environment during transportation. The USPS has stringent guidelines for shipping these materials, and all employees and customers must be aware of these regulations.
Classification of Dangerous Goods
Dangerous goods are classified into several categories based on their properties. The following are the primary classes defined by the U.S. Department of Transportation (DOT):
1. Explosives (Class 1): Materials that can explode or produce a dangerous reaction.
2. Gases (Class 2): Compressed gases, liquefied gases, and gases that may become hazardous when transported.
3. Flammable Liquids (Class 3): Liquids that can ignite easily, including solvents and fuels.
4. Flammable Solids (Class 4): Solids that can catch fire through friction, heat, or moisture.
5. Oxidizers and Organic Peroxides (Class 5): Substances that can cause or enhance the combustion of other materials.
6. Toxic and Infectious Substances (Class 6): Materials that can cause harm to human health, including biological agents.
7. Radioactive Materials (Class 7): Substances that emit radiation and are hazardous to health.
8. Corrosives (Class 8): Materials that can damage living tissue or severely corrode materials.
9. Miscellaneous Dangerous Goods (Class 9): Items that present a hazard during transportation but do not fit into the other classes.
