When responding to a fire incident with a transmitted 10-21, what type of fire should be expected?

A transmitted 10-21 generally refers to a brush fire incident. This designation indicates a specific type of fire that is often characterized by wildland or urban interface scenarios where vegetation is the primary fuel source. These fires can rapidly spread in certain conditions, especially in areas with dry brush, grass, or trees.

Brush fires typically require different tactics compared to fires in residential, vehicle, or commercial structures, as they often involve unconventional terrain and may necessitate specialized equipment and resources. Understanding the context of a transmitted 10-21 helps first responders prepare adequately for the unique challenges associated with brush fire incidents. This includes considerations like access, the potential for rapid spread, and the need for wildland firefighting techniques.
