What is the process for requesting additional resources during a large-scale incident per SOP202?

The correct choice outlines a structured approach to effectively manage resources during a large-scale incident. Assessing needs is a critical first step, as it helps in identifying the specific requirements for additional manpower, equipment, or support services. This assessment ensures that the request is based on a clear understanding of the situation on the ground.

Communicating with dispatch is equally vital, as it establishes a direct line to the command center or support teams, enabling them to coordinate and deploy resources efficiently. This communication helps to streamline operations and ensures that the response is rapid and well-organized, which is particularly important during large-scale incidents where time and accuracy can significantly impact outcomes.

The other options do not provide a proactive or effective means to handle resource requests. Waiting for resources to arrive does not address the immediate needs of the situation, potentially leading to delays in response and exacerbating the incident. Collecting information from bystanders may be useful for situational awareness but does not facilitate the necessary action for resource acquisition. Utilizing social media for such requests could create information overload or miscommunication, as it may not reach the appropriate channels quickly or effectively enough in an emergency context.
