What is the primary purpose of a size-up at the start of a wildland fire assignment?

• A. To assess fire behavior, fuels, topography, weather, and safety to guide suppression actions.
• B. To decide how long the shift will last.
• C. To select the exact equipment for the incident.
• D. To assign blame for the fire start.

Answer: (A)

The main point of a size-up at the start of a wildland fire assignment is to rapidly form a clear picture of the situation so you can decide how to fight the fire safely and effectively. By evaluating fuels, topography, weather, and early indicators of fire behavior, you anticipate how the fire may spread and where hazards lie. This information guides the suppression approach—whether to use a direct or indirect strategy, where to place lines, and which routes and safety zones are needed—so actions protect responders and important values. It’s also about setting safety priorities and establishing a plan for communications and contingencies. Other tasks like determining shift length, selecting equipment in detail, or assigning blame aren’t the primary purpose of the initial size-up.
