In the GHBMO sequence of events, where does the action of adsorption occur?

In the GHBMO (Gather, Handle, Burn, Maintain, Operate) sequence of hazardous materials response, adsorption typically occurs during the "Engulf" step. This is because adsorption involves the process by which molecules of a gas, liquid, or dissolved solid adhere to the surface of a solid or liquid. In this context, when hazardous materials are being handled, containment strategies often include techniques that utilize adsorption to effectively capture and immobilize pollutants, thereby preventing their spread and reducing the risk of exposure.

During the Engulf phase, responders might use materials such as absorbents (e.g., activated carbon, clay) to surround and bind with hazardous substances, facilitating safer handling and transport. This treatment is crucial for mitigating the hazard posed by spills or leaks. Therefore, the action of adsorption is most relevant and effectively applied during this phase of the sequence, ensuring that the hazardous material does not escape into the environment or pose additional risks to health and safety.
