Waste Compatibility

Chemical waste that are incompatible should not be mixed or stored together. If these wastes must be stored in the same area, they should be physically separated using secondary containment or another means that will prevent the materials from contacting each other in the event of a spill or leak.

The following are sources of information about compatibility:

• EPA Chemical Compatibility Chart
• RCRA Waste Compatibility Chart
• Laboratory Safety Manual Chemical Storage Information
• Mallincrodt Chemical Storage Chart

Container Compatibility

The container used for hazardous waste collection must be compatible with the waste and must not contain residues of incompatible materials.

The following table shows general chemical categories and compatible container types.

Take special care in choosing containers for the following wastes:

• Nitric Acid: reacts with organics (including acetic acid) to produce heat and gas. If product containers for organics are used to collect nitric acid, be sure to rinse thoroughly to avoid potential over-pressurization and subsequent burst of the container.
  
• Perchloric Acid and Organic Peroxides: highly reactive with organics and organic material, such as wood. May also react with metals.
  
• Hydrofluoric Acid: Dissolves glass containers
