After the collapse, what did the Deputy Chief (Command) request to assist on scene?

The request for a 4th and 5th alarm after the collapse signifies the need for a significant increase in personnel and resources to manage a complex emergency situation. Such a request is typically made in response to incidents that exceed initial response capabilities, particularly in cases where the scale of the disaster, like a structural collapse, requires more firefighters, equipment, and support services to ensure the safety of both responders and civilians.

By calling for additional alarms, the Deputy Chief is prioritizing the allocation of resources necessary for search and rescue operations, fire suppression, and potentially hazardous material containment. This level of response also ensures that medical personnel and logistical support units are brought in to manage any casualties or injuries that may arise from the incident. The request reflects a proactive approach to emergency management, emphasizing the importance of readiness for escalating situations and ensuring the overall safety and efficacy of the response effort.
