Where is the fire located?

• A. How many firefighters are on scene?
• B. What is the wind direction?
• C. Where is the fire located?
• D. What is the color of smoke?

Answer: (C)

Locating the fire is the critical first step in size-up because it directly guides the tactical plan: where to place hose lines, where to enter or remain outside, and how to protect exposures. Knowing exactly where the fire is allows you to target the attack, anticipate spread paths, and decide whether to operate offensively or defensively. The other prompts—how many firefighters are on scene, wind direction, or the color of smoke—provide important context for overall operations but do not tell you where the fire sits, which is essential for directing immediate actions and preventing further involvement. For example, wind direction affects ventilation and flow paths, but it won’t tell you which compartment is burning. Smoke color can indicate smoke conditions and fuel but not the precise location of the fire.
