What is a 3rd alarm MCI response comprised of?

The correct response outlining a 3rd alarm MCI (Mass Casualty Incident) response typically includes three engines and one truck. This configuration is designed to ensure that adequate resources are allocated for a situation that requires enhanced capabilities due to the severity of the incident.

When a third alarm is activated, it signifies that the incident has escalated, necessitating an increased level of response to support the operational demands. The inclusion of three engines provides necessary water supply and firefighting capabilities, while the truck is crucial for access, search and rescue operations, and providing additional support with its ladder and equipment.

A balanced response like this allows for effective management of the incident scene, including efficient triage, treatment, and transportation of patients, which is vital in a mass casualty scenario where time is of the essence in saving lives. Understanding this composition empowers responders to adequately prepare and allocate resources effectively in the event of a mass casualty incident.
