What is a prudent approach when planning with S-390 results?

• A. Use them to inform safe placement of lines and anchor points and maintain safety buffers
• B. Treat them as exact predictions with no validation
• C. Ignore them when time is short
• D. Disregard safety considerations

Answer: (A)

Using S-390 results to guide planning is about turning forecasted fire behavior into safe, actionable decisions. These results show where the fire is likely to move and how intense it could be under current conditions, so you can choose line locations and anchor points that are more likely to hold and protect crews. Designing with these findings helps you set safe buffers—mockets of space around the line to absorb unexpected changes in wind, fuels, or slope—giving crews a margin to maneuver or retreat if conditions shift. This approach keeps safety at the forefront while still aiming to contain the fire, because it translates predictions into concrete considerations like where to place anchors, how long a line should be, and how much separation is prudent from hazards. Always pair these results with real-time observations and weather updates and adjust your plan as conditions evolve. Relying on the results as exact guarantees or ignoring them undermines safety and can lead to dangerous outcomes.
