• A. Setting up barricades to block traffic
• B. Establishing a perimeter to keep unauthorized persons away
• C. Using loudspeakers to disperse crowds
• D. Deploying law enforcement to manage crowds

Answer: (B)

Establishing a perimeter to keep unauthorized persons away is a fundamental strategy for crowd control at hazardous materials incidents. This approach ensures that only authorized personnel, such as emergency responders and relevant on-site management, are allowed in the affected area. By creating a designated zone, emergency services can work more effectively without interference from the public or unauthorized individuals, reducing the risk of exposure to danger and allowing for a more organized response to the hazardous situation. Additionally, maintaining control of the perimeter helps to manage the flow of information and resources, ensuring that necessary operations can be carried out safely and efficiently.
