What physical method temporarily contains a liquid hazardous material for absorption or disposal?

The method used to temporarily contain a liquid hazardous material for absorption or disposal is containment. Containment refers to the physical barriers or procedures put in place to prevent the hazardous material from spreading or escaping from its designated area. This can involve using barriers such as dikes, berms, or liners to limit the area affected by the spill, allowing for safe absorption, cleanup, or disposal.

Containment is an essential action in emergency response, as it helps protect the environment, public health, and safety by limiting the exposure and spreading of hazardous materials. It allows responders to manage the incident more effectively and to plan for further actions needed to address the hazardous situation.

The other methods such as retention, control, and diversion may have their own specific applications in hazardous materials management but do not specifically focus on the temporary physical containment aspect that is critical for managing liquid spills and leaks.
