Which decontamination step directly addresses minimizing exposure to hazardous materials?

The step that directly addresses minimizing exposure to hazardous materials is removing or isolating the materials effectively. This action is fundamental in controlling the situation and preventing further contact with hazardous substances. By physically removing the source of contamination or isolating it, first responders can significantly reduce the risk of exposure to both individuals and the environment.

Neutralizing the materials immediately focuses on changing the chemical nature of the hazards, which can be beneficial but may not address exposure as directly as effective removal or isolation. Absorbing excess materials helps to limit exposure, but it is often a temporary measure and may not be sufficient for full decontamination. Informing the public about the hazards is essential for awareness and safety but does not physically mitigate exposure or eliminate the hazard itself.
