Which of the following is NOT a method mentioned for decontamination?

In the context of decontamination procedures, methods are employed to remove or neutralize hazardous materials to protect both people and the environment. Among the methods listed, cooling is not typically identified as a decontamination strategy.

Discarding involves the safe removal and disposal of contaminated materials to eliminate the hazard. Dilution refers to reducing the concentration of a harmful substance, often with water or another solvent, to make it less harmful. Absorption entails using materials that can soak up contaminants, effectively reducing their presence and potential harm.

Cooling, while it may be useful in certain emergency situations to mitigate heat or facilitate handling of materials, does not specifically serve the function of decontaminating contaminants and is not recognized as an effective method for addressing hazardous materials. Hence, it qualifies as the option that does not fit within recognized decontamination practices.
