Fire

How to start, maintain, and use fire for warmth, water purification, signaling, and morale.

Three Keys to Fire

  1. Preparation matters more than ignition. Spend 80% of your time gathering and sorting fuel before you strike a single spark.
  2. Tinder must be bone-dry and fine. If your tinder isn't right, nothing else will work.
  3. Start tiny. A fire grows from ember → tinder → kindling → fuel. Skip a step and it dies.

1. Why Fire Matters

Fire does five critical things in survival:

2. Preparing Your Fire

Before you try to light anything, gather and sort three categories of fuel:

1. Tinder (catches a spark)

Must be absolutely dry, fine, and fluffy. Size of a baseball to grapefruit-sized bundle. See section 3.

2. Kindling (catches from tinder)

Small sticks, pencil-thickness and thinner. Dead twigs still attached to trees are typically dryer than those on the ground. Gather a double armload — you think you have enough, you don't.

3. Fuel (sustains the fire)

Wrist-thick to arm-thick pieces. Dead standing wood is best. Avoid green wood (it hisses and smokes) and rotting wood (crumbles and smolders). Start with smaller fuel and increase size as the fire grows.

Rule of thumb: Gather three times more fuel than you think you'll need. Then gather more. Running out of fuel at 2 AM in the cold is a serious setback.

4. Ignition Methods

Lighter or matches (easiest)

Hold flame under your tinder bundle. Shield from wind with your body. A lighter works in rain if you keep it dry in your pocket. Wet matches can be dried by running them through your hair (the oils help).

Ferro rod / fire steel

Scrape the rod firmly with a knife spine or sharp edge at a 45° angle, directing sparks into the tinder. Hold the rod close to the tinder — don't swing from a distance. The striker should move, not the rod.

Flint and steel

Strike a piece of hard steel (back of knife blade, file) against sharp flint, quartz, or jasper. Catch the spark on char cloth or very fine tinder.

Battery and steel wool

Touch both terminals of a battery (9V works best, but any battery works) to fine steel wool. It ignites instantly. Place it in your tinder bundle immediately.

Fire plow (primitive — difficult)

Rub a hardwood shaft rapidly back and forth in a groove cut in a softwood base. Friction creates a fine dust that eventually ignites. This requires considerable effort and practice.

Bow drill (primitive — effective with practice)

  1. Fireboard: A flat piece of dry, soft wood (cedar, willow, cottonwood). Cut a V-shaped notch to the edge.
  2. Spindle: A straight, dry stick about 2 cm thick and 30 cm long. Same wood or harder.
  3. Bow: A slightly curved branch with cordage tied between the ends (shoelace, paracord, strip of clothing).
  4. Socket: A harder piece of wood or stone with a small depression to hold the top of the spindle.
  5. Wrap the bowstring once around the spindle. Place the spindle in the fireboard notch. Press down with the socket. Saw the bow back and forth rapidly.
  6. Fine, dark dust collects in the notch. When it begins to smoke on its own, tip it onto your tinder bundle and blow gently.
If you carry one extra item in your pack, make it a lighter. Even a cheap disposable lighter gives you thousands of flames and works when wet if kept in a pocket. A second lighter or ferro rod is smart insurance.

5. Fire Structures

Teepee fire (best for starting)

Place your tinder bundle in the center. Lean kindling sticks around it in a cone shape, leaving a gap on the windward side for lighting and airflow. Light the tinder from the windward gap. As kindling catches, add larger sticks in the same teepee pattern.

Log cabin fire (long-lasting)

Stack fuel in alternating layers like a log cabin, with tinder and kindling in the center. Burns steadily and collapses inward, creating a good coal bed.

Long fire (for sleeping beside)

Lay two long, thick logs parallel, about 30 cm apart. Build your fire between them. The logs contain the fire, reflect heat, and the fire burns along their length. Excellent paired with a lean-to shelter.

Star fire (fuel conservation)

Arrange 4–5 long logs in a star pattern with their ends meeting at the center. Light the center. As the ends burn down, push the logs inward. Good when fire fuel is limited.

6. Maintaining a Fire

7. Fire in Wet Conditions

Making fire in rain is one of the hardest survival skills. Here's how to improve your odds:

The most common mistake in wet conditions: giving up too early. The first few minutes of a fire in rain are smoky and discouraging. Keep feeding fine, dry material. Once you have a coal bed, rain on top won't easily kill it.

8. Signal Fires

9. Fire Safety

Never use fire inside an enclosed shelter. Even a large shelter with a seemingly adequate opening can accumulate lethal carbon monoxide. If you must warm a shelter with fire, use heated rocks instead: warm them in the fire, then move them inside.
