What does Code 10 signify?

• A. A specific classification indicating a particular type of emergency situation.
• B. A routine non-emergency status.
• C. A code for weather advisory.
• D. A code for equipment inspection.

Answer: (A)

In fire department communications, codes like this are used to convey a specific kind of emergency quickly. This code signifies a specific classification indicating a particular type of emergency situation, which tells responders exactly what kind of incident they’re dealing with and what resources or actions are needed. It isn’t used for routine non-emergency status, weather advisories, or equipment inspections, which would be described or flagged in other ways. Since codes can differ by department, always use your agency’s defined meanings, but the essential idea is that this code communicates a defined emergency type so crews can respond appropriately.
