Ngir yéeg tundu bu tàggatul, daw ci liiñ bu lakk bi ngir jàll ci barab bu lakk bi dafa melni lu doy waar. Waaye ci taarixu fay lakk yi ci àll bi, jàll ci "The Black" muccal na téemeeri dundu ci noonu la daw lakk bi ci broos bu lakkul ("The Green") dafa jur luy ray nit.

• Bàyyil sa sac à dos ak sa vest synthetik.
• Pour water from your bottles over your wool/cotton clothing, hair, and a cotton bandana tied over your nose and mouth.
• Shield your face and eyes with your gloved or covered forearms, hold your breath for the 3-second dash, and step briskly through a low gap in the flames onto the burned black ground.
• Walk 30 to 50 meters (100 to 165 feet) deep into the black until the ground feels cool and radiant heat from the unburned green edge diminishes.
• Hazards to watch for inside "The Black":
• Falling "Widowmaker" Snags: Burned standing trees and hollowed-out roots collapse without warning after a fire passes. Stand in a clearing inside the black well away from the height of any burned trees.
• White Ash Pits: Deep pockets of fluffy white ash indicate burned-out tree stumps or root systems still glowing at 500 degrees Celsius (932 degrees Fahrenheit) underground. Stepping into a white ash pit causes catastrophic third-degree foot and leg burns. Step only on solid rock or thin black char, never into deep white ash depressions.
• Re-burn in Unburned Canopy: If only the ground needle litter burned ("underburn") while the green pine needles in the overhead tree crowns are still intact and unburned, a sudden wind shift can still cause a crown fire re-burn overhead. Only rely on The Black where either the canopy also burned or there are no dense overhead tree crowns.

Phase 3: Selecting a Last-Resort Survival Zone when overrun¶

If the wildfire is advancing too fast to escape and the flames are too tall (3+ meters / 10+ feet) to punch through into The Black, you have minutes to pick a Last-Resort Survival Zone to survive the passage of the flame front.

What kills you during an overrun: Radiant Heat and Superheated Gas¶

You do not have to be touched by a single flame to die in a wildfire. Two invisible killers precede and accompany the flame front:

1. Radiant Heat (Infrared Radiation): Travels in straight lines at the speed of light from the wall of flames. At 10 meters (33 feet) from a major crown fire, radiant heat flux exceeds 40 to 80 kilowatts per square meter, enough to blister bare human skin in 3 seconds and ignite clothing. Because radiant heat travels strictly in straight lines (line-of-sight), placing any solid, non-flammable barrier (a boulder, a dirt bank, a deep trench, or water) between your body and the flame wall blocks 100% of direct radiant heat.
2. Convective Superheated Air (Thermal Airway Injury): Turbulent gusts of superheated air (300 to 800 degrees Celsius / 572 to 1,472 degrees Fahrenheit) roll ahead of and through the flame front. Inhaling one breath of 300-degree air causes immediate laryngeal edema (swelling of the voice box and windpipe) that seals the airway shut. However, because hot air rises, the air layer within 10 to 15 centimeters (4 to 6 inches) of bare mineral dirt stays hundreds of degrees cooler and retains breathable oxygen.

Ranking Last-Resort Survival Zones from Best to Worst¶

Step-by-step Overrun Survival Procedure (The 10-Minute Flame Pass)¶

In most forest and brush wildfires, the intense flaming front takes only 2 to 10 minutes to pass over a stationary point (though smoke, embers, and radiant heat from burning logs continue afterward). If you are forced to lie down in a clearing, road cut, or behind a boulder:

1. Throw your backpack and stove fuel canister 20 meters (65 feet) away. Keep only your water bottles, a wool/cotton garment or leather gloves, and your satellite SOS device in a pocket underneath your torso.
2. Cover every square centimeter of bare skin with non-synthetic fabric and soil: Pull down cotton/wool sleeves, turn up your collar, put on leather or wool gloves, and pull a wet cotton bandana or merino wool buff over your nose, mouth, and ears. If you have bare arms or legs, rub wet mud or loose mineral dirt thickly over your exposed skin to reflect infrared heat.
3. Dig a "Breathing Pocket" in the dirt: Scrape a fist-sized hollow in the cool, damp mineral dirt directly beneath your nose and mouth. Press your face firmly into that dirt hollow with your damp cotton/wool cloth covering your mouth and nose.
4. Stay flat and DO NOT GET UP when the roar and heat peak: As the flame front hits the edge of your clearing, the noise will sound like a jet engine, darkness will be total, embers will shower your back, and the heat on your back and calves will be agonizing. Do not panic, do not lift your head to gasp, and do not stand up and run. Standing up puts your lungs into 500-degree-Celsius air and guarantees fatal airway burns within two breaths. Stay pressed flat into the dirt breathing slow, shallow breaths from the soil pocket until the roar subsides and the air cools.

Phase 4: Vehicle entrapment at a trailhead or forest road¶

Sometimes hikers make it back to their parked car at a remote dirt trailhead only to find the single-lane forest road out is already cut off by flames or fallen burning trees.

• A parked trailhead vehicle is safer than running on foot through burning brush, provided you position the car properly:
• Park on the barest ground available: Drive onto the center of the widest bare dirt/gravel parking pad or rocky turnout, as far away from trees, brush, and wooden trailhead kiosks as possible. Do NOT park over dry tall grass or pine needle beds (which will ignite directly underneath your gas tank and catalytic converter).
• Keep the engine idling (until oxygen drops) with headlights and hazard flashers ON: Keeping headlights and emergency flashers on allows firefighters and helicopters to spot your vehicle through dense black smoke.
• Roll all windows 100% UP and set climate control to "RECIRCULATE" (or turn vents OFF): Never leave windows cracked open; glowing embers and superheated toxic gas will blow inside the cabin.
• Get down on the vehicle floorboard below the window glass line: Window glass transmits radiant infrared heat directly onto your face and arms (and tempered side windows can shatter from extreme heat). Lie down on the floor mats below the level of the metal doors, and cover everyone completely with wool blankets, cotton jackets, or spare clothing/floor mats (never synthetic sleeping bags).
• Expect loud noises and stay inside until the main flame front passes: Tires may pop and melt, exterior plastic trim may catch fire, and heavy gusts will rock the vehicle. Modern automotive fuel tanks rarely explode immediately; stay low under the window line inside the metal cabin until the outside flame wall moves past, then exit onto the burned bare dirt upwind if the vehicle exterior catches fire.

Phase 5: Post-fire medical triage and navigating out of the burn zone¶

Once the main fire front has passed and the air cools enough to stand up:

1. Check for Airway Thermal Burns (Red Flag Number 1): Look at your companions' faces. Singed nasal hairs, soot around the mouth or in sputum, a hoarse or raspy voice, brassy cough, stridor (high-pitched wheezing when inhaling), or difficulty swallowing indicate inhalation thermal injury. The upper airway can swell completely shut over the next 1 to 4 hours. Re-trigger your Satellite SOS immediately and report "Suspected airway burns requiring immediate helicopter hoist/evacuation." Keep the victim sitting upright (semi-Fowler's position) to reduce airway swelling and minimize physical exertion.
2. Treat Cutaneous Burns Correctly: Cool active burns with clean cool water from your drinking bottles for 10 to 20 minutes if available, remove any melted clothing ONLY if it is not stuck to the skin (never peel melted nylon or polyester out of a burn wound; cut around it), and cover burns loosely with clean dry gauze or a clean cotton shirt (see Lakk). Protect burn victims from hypothermia once the heat subsides.
3. Navigate Out Using "The Black" While Avoiding Post-Fire Deadly Hazards:
4. Never walk back into unburned green brush where shifting winds can reignite the flank. Stay inside The Black or on wide bare roads while waiting for rescue crews.
5. Watch overhead continuously for falling burned trees ("Widowmakers") and underground burned-out root cavities / white ash pits that collapse under a hiker's boot.
6. Beware of rolling rocks and debris on steep slopes: In steep mountain canyons, wildfires burn away the logs and brush holding talus rocks in place, sending bowling-ball-sized rocks tumbling down onto trails continuously after the fire passes.
