Which process involves the physical picking up of a liquid hazardous material?

The process that involves the physical picking up of a liquid hazardous material is absorption. Absorption refers to the ability of a material to draw in or take in another substance, often a liquid, into its bulk. In the context of hazardous materials, absorption would involve a substrate, such as a sponge or absorbent material, that physically collects and retains the hazardous liquid within its structure.

This process is critical in emergency response as it allows responders to effectively manage spills and mitigate the risk of further contamination or harm in the environment. By absorbing the liquid hazardous material, responders can prevent it from spreading and enable safer clean-up operations. Understanding absorption is vital for Incident Commanders and first responders to ensure proper handling of hazardous materials during incidents.
