What grid is used in Point/Spot Firing?

• A. 2x3 chain grid
• B. 3x4 chain grid
• C. 1x2 chain grid
• D. 4x5 chain grid

Answer: (C)

Point/Spot firing hinges on laying out a pattern of ignition points so you can control where and how the fire burns. The grid spacing determines how closely those spots are lit and how the fire progresses. A 1x2 chain grid means spacing one chain in one direction and two chains in the other, creating a compact array of ignition points. This arrangement provides enough coverage to start and sustain a controlled burn while keeping individual ignition spots close enough to interact and form a steady front, yet spaced enough to avoid a single, overly intense heat patch. It also makes it easier to monitor flame behavior and intervene if needed. Larger grids would leave gaps that could let the fire jump or burn unevenly, while denser grids might produce too much heat in one area. So, for Point/Spot Firing, the 1x2 chain grid is the appropriate pattern.
