Hazardous Material Disposal and Management
Compiled by Jim Szpakowski

Hazardous Material: is any solid, liquid, or gas that can harm people, other living organisms, property, or the environment. The term hazardous material is used in this context almost exclusively in the United States. The equivalent term in the rest of the English-speaking world is Dangerous Goods. A hazardous material may be radioactive, flammable, explosive, toxic, corrosive, biohazardous, an oxidizer, an asphyxiant, an allergen, or may have other characteristics that make it hazardous in specific circumstances.

Dangerous Goods: are substances which pose risk to health, safety, property or the environment during operation and/or transportation. (In the United States, the equivalent term is Hazardous Material.) They are divided into classes on the basis of the specific chemical characteristics producing the risk. (Wikipedia)
