What is one responsibility of the third due company in a mass casualty incident (MCI)?

In a mass casualty incident (MCI), the responsibilities of responding companies are critical to ensuring an organized and effective response. The third due company plays a vital role in establishing ingress and egress routes for ambulances. This responsibility is crucial because it ensures that emergency vehicles can access the scene quickly to transport patients and can also evacuate those requiring urgent medical attention.

By establishing these routes, the third due company helps maintain a continuous flow of traffic necessary for an efficient response, minimizing delays that could jeopardize patient outcomes. Proper ingress and egress routes also help in managing the overall scene safety, allowing first responders to operate without the added complication of obstacles or congestion caused by emergency vehicle movement. This contributes to a more coordinated and effective response in a chaotic situation like an MCI.
