Ridgeline Escape Route Compromised
You are a first-year FFT1 supervising a 12-person hand crew on a ridge above a 40-acre fire in a drainage. The slope is 35%, fuel model 10, and live fuel moisture is low. At 1415 the wind is 12 mph gusting 20 from the southwest, temperature 92°F, relative humidity 18%. The fire is spotting about 1/8 mile ahead. Your escape route is a brushed-in old dozer line that runs down the ridge to a blackened safety zone; it takes about 12 minutes at normal pace. One crew member has a minor ankle sprain and is moving slowly. At 1430 the wind shifts to the northwest and increases to 18 mph gusting 28. A spot fire crosses the lower third of the escape route. The radio channel is busy with traffic from two engines and a dozer. You have one sawyer and one swamper.
1. Using LCES, identify which elements are failing and explain what makes this a high-risk decision point rather than a routine spot fire.

LCES is failing as a system, not just one component. Lookouts: no dedicated lookout; the crew is focused on line construction and smoke is limiting view. Communications: the tactical channel is congested with engine and dozer traffic, so a warning may not get through. Escape route: the spot fire has crossed the lower third of the only route to the black, so the route is no longer reliable. Safety zone: 12 minutes at normal pace is too long with an injured crew member and a wind-driven fire; effective travel time is longer. The wind shift, increased gusts, spot below the escape route, and unburned fuel between crew and fire match several Watch Out Situations. This is a high-risk decision point because the fire can close the route while the crew is committed above it. The correct frame is not 'can we catch the spot' but 'can we guarantee escape if the spot runs.' If not, disengage and re-establish LCES before any line work.
2. What immediate actions would you take in the next 5 minutes, and would you order shelter deployment? Explain the decision criteria.

Immediate actions: stop saws and line construction, call a head count, and move the crew toward the pre-identified black or a cleared area away from the spot's likely run. Assign one firefighter to the ankle injury and another as lookout; drop tools if they slow movement. Do not commit to the spot fire. Shelter deployment is a last resort, not a first action. Use it only if the fire is imminently threatening and the crew cannot reach a survivable area. Decision criteria: time-to-arrival versus time-to-safety-zone, flame length and radiant heat, whether the route is still open, and whether the deployment site is clear of heavy fuels. If the spot is still small and the route is open, move. If the route closes and flames will reach the crew before they can clear the area, deploy in the largest cleared area, face down, and protect airways. The injured member's slower pace is critical; do not let the crew split.
3. Draft a concise radio report to the division supervisor that includes the critical facts and your intended action.

Use a priority call and keep it short: 'Division, Crew 1, priority traffic. We are on the ridge above the drainage. Wind shift and spot fire have crossed our lower escape route. LCES is compromised. I have 12 personnel, one minor injury. We are disengaging to the black and will report when accounted for. Request you hold engine and dozer traffic off this channel unless emergency.' Then confirm receipt and give a follow-up time. The report includes who, where, what changed, current action, and need. Avoid a long explanation on a congested channel. If no answer, repeat once, then use an alternate channel or relay through dispatch. Document the time and content.
