Loading Zone


A large open area where all casualties from an incident are assembled, organized, and loaded into awaiting ambulances that then transport to directed hospitals. Typically used when casualties outnumber available transport ambulances.

Mobile Command


The Incident Commander is performing command functions in addition to other critical duties, such as a first arriving officer moving to contact a shooter. Another responder should assume Command (and establish a stable Command) as soon as practical. Mobile Command  is sometimes referred to as a “working command.”
