Which term describes materials that could pose a hazard if mixed?

The term that describes materials that could pose a hazard if mixed is incompatible materials. Incompatible materials refer to substances that, when combined, can cause dangerous reactions such as explosions, the release of toxic gases, or other chemical reactions that could harm people or the environment. This classification is critical in fields such as medical gas handling and chemical storage, where the safety of procedures can depend significantly on avoiding the combination of specific materials.

Understanding incompatibility is essential for ensuring safe storage, handling, and transportation of various substances. For instance, in the context of medical gases, certain gases must not come into contact with each other to prevent hazardous reactions. This knowledge is vital for compliance with safety regulations and for maintaining a safe working environment.
