Dangerous waste basics

Most businesses in Washington generate some type of dangerous waste — waste that’s potentially harmful to health and the environment. You are responsible for handling and disposing of your waste properly.

This page offers videos, guidance documents, and posters to help you better understand this topic.

What is dangerous waste?

Washington uses the term "dangerous waste," while federal law uses the term "hazardous waste." Washington's Dangerous Waste Regulations, while based on the federal Resource Conservation and Recovery Act (RCRA), are more protective than federal rules. The term "dangerous waste" includes more wastes than the federal definition.
