NOTE: Descriptions along diagonal are properties of materials by themselves.
All potential material interactions should be examined for incompatibilities. Even if process materials are relatively
non-hazardous when considered independently, some potentially dangerous interactions may occur when materials
are combined. Interactions between process chemicals, containment materials, and other materials with which the
chemicals come in contact can be examined in pairs by using an interaction matrix.
