If there is a structure fire with flames and active operations, what code is most appropriate?

• A. FSTRW
• B. FSTR
• C. FTRA
• D. FTRE

Answer: (A)

The main idea here is signaling that the fire is actively being fought and resources are on scene. When flames are present and crews are conducting fire attack and other suppression operations, the appropriate code marks it as a working fire. That communicates to all responders that this is an active incident requiring coordinated efforts, more units, and a heightened safety posture.

The code that fits this scenario is Structure Fire - Working. The “Working” portion (the W) signals that suppression actions are underway, not just a reported or potential fire. This distinction matters because it triggers the right level of response and resource allocation, and alerts arriving units to expect ongoing operations, possibly water supply needs, ladder assignments, and longer scene times.

Other codes don’t convey the same status. A plain Structure Fire describes the incident type but not the active operations. Codes that imply rescue or other modifiers would suggest a specific condition (like occupants trapped or a different priority) that isn’t stated here.
