EXAMPLES OF POTENTIALLY INCOMPATIBLE
				  WASTE
Many hazardous wastes, when mixed with other waste or
				  materials at a hazardous waste facility, can produce effects which are harmful
				  to human health and the environment, such as (1) heat or pressure, (2) fire or
				  explosion, (3) violent reaction, (4) toxic dusts, mists, fumes or gases, or (5)
				  flammable fumes or gases.
Below are examples of potentially incompatible wastes, waste
				  components, and materials, along with the harmful consequences which result
				  from mixing materials in one group with materials in another group. The list 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.
This list is not intended to be exhaustive. An owner or
				  operator must, as the regulation requires, adequately analyze his wastes so
				  that he can avoid creating uncontrolled substances or reactions of the type
				  listed below, whether they are listed below or not.
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).
In the lists below, the mixing of a Group A material with a
				  Group B material may have the potential consequence as noted.
