How to Use

Handle chemical waste materials as hazardous substances unless they are on the List of Non-Hazardous Chemical Wastes. Used hazardous materials containers are an exception, however. The Empty Container Decision Tree determines whether they are hazards.

To use the Empty Container Decision Tree, the container must be completely empty. This means:

  • No liquid can be removed by tilting or inverting the container
  • No solid materials can be removed by scraping or chipping
  • Aerosols are used to the maximum extent under normal use
