What is dangerous waste?

Washington state uses the term "dangerous waste" rather than the federal law's term of "hazardous waste." This is because Washington state's Dangerous Waste Regulations are more protective than federal laws. The definition of "dangerous waste" is more expansive than "hazardous waste."

When is a product dangerous waste?

Products used by businesses may qualify as dangerous waste once they are discarded or no longer have a use (i.e., become a waste). The only way to know for sure if something is dangerous waste is to designate it.

  • Learn how to designate your waste.
  • Look for products labeled “DANGER,” “FLAMMABLE,” “WARNING,” “POISON,” or something similar. When these products become waste, they may be considered dangerous waste.
