Refer to our HAZARDOUS WASTE IDENTIFICATION page for a complete description, including all definitions, applicable regulations and "listed wastes".
According to Federal Regulations CFR 40, parts 100 - 399, a Hazardous waste is a solid, a semi-solid, a liquid, or a contained gas that, "because of its quantity, concentration, or physical, chemical, or infectious characteristics, it may cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness or pose a substantial present or potential hazard to human health and the environment when improperly treated, stored, transported, or disposed of, or otherwise managed. "
A Chemical Waste is HAZARDOUS if it exhibits one or more of the following characteristics:
- Ignitability
- Corrosivity
- Reactivity
- Toxicity
In addition, specific materials have been designated or "listed" by the Federal Government specifically as a hazardous waste, regardless of the characteristics of the material, because the material is believed to meet the statutory definition of a hazardous waste. Four specific lists of designated hazardous waste are :
- F Series - designates hazardous wastes from nonspecific sources
- K Series - designates hazardous wastes from specific sources
- P Series - designates acutely hazardous wastes from commercial chemical products
- U Series - designates toxic hazardous wastes from commercial chemical products
