What is the primary purpose of performing mass decontamination?

The primary purpose of performing mass decontamination is to remove immediate threats of hazmat exposure. In the context of a hazardous materials incident, individuals who have come into contact with contaminated substances pose a risk not only to themselves but also to rescuers and others in proximity. Mass decontamination aims to quickly and efficiently strip away hazardous materials from victims to mitigate further exposure and prevent the spread of contaminants.

By addressing the potential for harm resulting from exposure, emergency responders protect the health and safety of individuals affected by the incident. This rapid action is crucial to avoid the escalation of health risks, allowing for further medical attention to be given once the immediate danger has been mitigated. Other options, while relevant in different contexts of emergency response, do not capture the essence of the primary function of mass decontamination in a hazardous materials scenario.
