In strip firing with multiple igniters, if slope is pushing the fire AWAY FROM your control line, which pattern should you use?

• A. 1,2,3
• B. 2,3,1
• C. 3,2,1
• D. 2,1,3

Answer: (C)

Ignition sequencing in a strip is used to control how the burn front moves toward the control line and to establish a burned edge (black) next to that line. When the slope tends to push the fire away from the control line, you want the burn to progress toward the line and finish with the area closest to the line already burned. So you start at the far end (the point farthest from the control line), then ignite the middle, and finally the point nearest the control line. This pattern makes the fire front move toward the line first, and the last ignition near the line helps create a solid black along the control line, reducing the chance of the fire crossing. Starting near the control line first would risk the fire running away and escaping before a secure edge is established.
