Fire Science

4. Fires involving energized electrical equipment like wiring or appliances.
6. A method of creating fire through friction, converting kinetic energy into heat.
9. The three essential elements—Oxygen, Heat, and Fuel—that must be present simultaneously for a fire to exist.
11. Indicated by a Yellow Flame (or "safety flame"), which is cooler and produces soot.
12. Wood ranging from pencil-sized to thumb-sized used to burn long enough to ignite larger logs.
13. A metal alloy rod that produces sparks between 3,000°F and 5,000°F when scraped.
15. A natural, resin-soaked pine wood used as a highly effective tinder.
16. Fires involving combustible metals such as magnesium or potassium.
18. The process that allows a fire to sustain itself; interrupting this reaction is one method of fire suppression.
20. Fires involving ordinary combustibles like wood, paper, and cloth.

1. The four-step technique for using a fire extinguisher: Pull the pin, Aim at the base, Squeeze the lever, and Sweep from side to side.
2. A tool used to create fire by concentrating solar radiation onto a point.
3. Highly combustible material, roughly the size of pencil lead, used to catch the first spark or flame.
5. Indicated by a Blue Flame, representing the most efficient and highest heat.
7. The material being oxidized during combustion, such as wood or gas.
8. Fires involving commercial cooking oils and fats.
10. Wood that is wrist-sized or larger used to provide long-term heat and light.
14. The catalyst for fire; approximately 16% is required in the air for combustion to occur.
17. The energy required to reach a material's ignition temperature.
19. Fires involving flammable liquids such as gasoline, oil, or grease.
