Fire triangle and fuels
- Tinder – Very fine, dry material that catches from a spark or small flame: dry grass, birch bark, fine wood shavings, cotton, paper.
- Kindling – Thin dry twigs and splits from about matchstick to thumb thickness.
- Fuel wood – Thicker dry wood, added only once the kindling is burning strongly.
- Let air in – Stack fuel loosely so air can flow in from below.
Danger: Never pour petrol (gasoline), spirit, lighter fluid or other flammable liquids onto a fire or embers. The vapours can ignite explosively and cause severe burns.
