What is an ignition sequence?

• A. The random distribution of ignition points.
• B. The planned order and timing of ignition points to achieve desired fire behavior and control.
• C. The number of ignition devices used.
• D. The color coding of ignition sources.

Answer: (B)

An ignition sequence is the planned order and timing of ignition points to shape fire behavior and keep the burn under control. By deciding where to light first and how quickly to advance the burn, you can control the rate of spread, direction of the fire front, and heat intensity to meet objectives while maintaining safety and holding capability. This approach uses tactics like back, flank, or head ignitions in a deliberate sequence to progress along a boundary, match wind and slope, and create a predictable, manageable burn. It’s not about lighting points randomly, the number of devices, or color coding, since those aspects don’t determine how the fire will actually move or how controllable it will be.
