What is the purpose of establishing a perimeter around a hazardous materials incident?

Establishing a perimeter around a hazardous materials incident is crucial for isolating the threat and limiting the spread of contamination. By creating a defined boundary, emergency responders can prevent unauthorized individuals from entering the area, thereby protecting both the public and response teams from exposure to hazardous materials. This containment strategy ensures that the hazardous substance does not migrate beyond the designated area, which is vital for controlling the situation and conducting clean-up operations safely.

Furthermore, a secure perimeter allows first responders to focus on mitigating the incident without distraction or interference, while also enabling effective surveillance and monitoring of the situation. This approach is an essential practice in emergency response protocols to protect public safety in hazardous materials incidents.
