What is a key risk associated with mistimed ignition in a direct attack?

Explanation:
Mistimed ignition in a direct attack creates a high risk that flames and heat will move toward the crews or their escape routes. In a direct attack, ignition ahead of the main fire is timed to help burn out fuels between the fire and the line, shaping the burn so firefighters can work safely. If the timing is off, the burnout can surge when crews aren’t in a safe position, or wind and fire behavior can carry flames toward the firefighters, push the fire toward unprepared areas, or create spot fires beyond the control line. This unpredictability can lead to rapid flare-ups, loss of the intended line, or entrapment, which is the core danger in mistimed ignition. The other statements don’t reflect how ignition timing affects control or crew safety—timing doesn’t instantly make the fire easier to control, fuel moisture doesn’t dramatically change because of the ignition moment, and fires don’t self-extinguish instantly.
