Chemical compatibility refers to the ability of two or more substances to exist together without undergoing undesirable chemical reactions. This concept is critical in hazardous materials management, particularly in the context of START and ICS protocols, where the safe handling and storage of chemicals are paramount. Not to be confused with chemical reactivity, which focuses on the potential for a chemical to undergo a reaction, compatibility emphasizes coexistence without adverse effects. In hazmat and CBRN operations, it is often referenced alongside scene control concepts such as Hot, Warm, and Cold Zones and decontamination corridors to clarify operational boundaries.
