B. Appendix B- Examples of Potentially Incompatible Waste1

1. Many hazardous wastes, when mixed with other waste or materials at a hazardous waste facility, can produce effects that are harmful to human health and the environment, such as:
a. heat or pressure;

b. fire or explosion;

c. violent reaction;

d. toxic dusts, mists, fumes, or gases; or

e. flammable fumes or gases.

2. Paragraph 5 of this Appendix contains examples of potentially incompatible wastes, waste components, and materials, along with the harmful consequences that result from mixing materials in one group with materials in another group. Paragraph 5 is intended as a guide to owners or operators of treatment, storage, and disposal facilities, and to enforcement and permit-granting officials, to indicate the need for special precautions when managing these potentially incompatible waste materials or components.

3. The tables in Paragraph 5 are not intended to be exhaustive. An owner or operator must, as the regulations require, adequately analyze his wastes so that he can avoid creating uncontrolled substances or reactions of the types listed in Paragraph 5, whether they are listed in Paragraph 5 or not.

4. It is possible for potentially incompatible wastes to be mixed in a way that precludes a reaction (e.g., adding acid to water rather than water to acid) or that neutralizes them (e.g., a strong acid mixed with a strong base), or that controls substances produced (e.g., by generating flammable gases in a closed tank equipped so that ignition cannot occur, and burning the gases in an incinerator).

5. In the tables below, the mixing of a Group A material with a Group B material may have the potential consequence as noted.
