In hazardous material terminology, what does absorption refer to?

Absorption refers to the process in which a substance is taken up and integrated into another material. In the context of hazardous materials, this often involves a hazardous liquid being soaked into another solid or liquid material, such as protective gear or absorbent materials. This process is critical for managing spills or leaks, as it helps contain and minimize the spread of hazardous substances.

The other options describe different interactions that do not align with the concept of absorption. For example, sticking to the surface represents adhesion, while blocking harmful substances may refer more accurately to filtration or barrier methods. Preventing chemical reactions involves strategies related to chemical compatibility and safety precautions, which are distinct from the concept of absorption. Understanding absorption is essential for effective hazardous material response and cleanup strategies.
