One critical factor to consider regarding the public when responding to a hazardous materials incident is their proximity to the incident and potential exposure risk. This aspect is vital because it directly relates to the safety and health of individuals in the area. Assessing how close people are to the hazardous materials helps determine the level of risk they face from exposure to harmful substances, which may require evacuation, sheltering in place, or providing specific information on protective actions.

Understanding proximity allows responders to effectively implement safety measures, including establishing exclusion zones, providing timely warnings, and ensuring that the public is informed about the risks associated with the incident. Addressing proximity enables an organized and efficient response, reducing the potential for harm to the public and helping to maintain order during a potentially chaotic situation.
