A hazardous waste is a waste that, because of its quantity, concentration, or physical, chemical, or infectious characteristics, may cause or significantly contribute to an increase in mortality or serious, irreversible or incapacitating illness, or may pose a substantial present or potential hazard to human health or the environment when improperly managed, stored, transported, treated or disposed of. In practice a waste is classified as hazardous either because it exhibits one or more of a defined set of characteristics (ignitability, corrosivity, reactivity, toxicity), or because it appears on a specific regulatory list of hazardous wastes/substances.
