During a mass casualty incident, what is the designated area where ambulances meet and organize arrivals?

• A. Treatment area
• B. Staging area
• C. Triage zone
• D. Reassessment bay

Answer: (B)

In mass casualty incidents, keeping the flow of patients and resources orderly relies on clear zones. The staging area is the space near the incident where ambulances meet, check in, and wait to be assigned missions or transport. This arrangement lets the incident commander assess available units, avoid crowding at the scene, and coordinate which patients go to which hospitals. It also gives responders time to prep equipment and organize supplies without cluttering the care areas. The treatment area is where patients receive care, the triage zone is where patients are sorted by acuity, and a reassessment bay isn’t a standard on-scene designation.
