What is the fire triangle?

• A method for starting fire using three tools
• The three basic needs for fire: heat, oxygen, and fuel
• A type of flame that forms a triangular shape
• The three ways fire spreads: conduction, convection, and radiation
• A natural phenomenon where fire moves in three directions

Why does blowing on a campfire make it burn brighter?

• It increases the heat of the firewood
• It removes the smoke and lets the fire "breathe"
• It adds more oxygen, which fuels the combustion process
• It speeds up the flash point of the fuel
• It spreads the fire wider to new fuel sources

What is the purpose of a fire extinguisher?

• To lower the flash point of the fire
• To remove one or more elements of the fire tetrahedron
• To increase the speed of oxidization to control flames
• To add water to the fire and make it spread
• To reduce the fuel available to the fire by breaking it down

What is a major reason wildfires spread so quickly?

• The fire triangle cannot be stopped
• Convection carries embers to new areas
• Oxidization happens too fast to control
• Water cannot extinguish fire in forests
• Firefighters have to remove the fuel manually

Which of the following statements about flames is true?

• They always appear orange, regardless of the temperature
• They are solid, stable structures that do not move
• They cannot exist in environments without oxygen
• They can only burn in open air, not in controlled environments
• They do not produce gases when burning

Which fire-starting method is MOST likely to be used in a survival situation?

• A disposable lighter
• Flint & steel
• A match
• A safety match
• A candle

Which material is MOST likely to have a low flash point?

• Dry wood
• Cooking oil
• Gasoline
• Candle wax
• Paper

If early humans had never learned to control fire, which of the following would be MOST different today?

• The way people communicate
• The development of human languages
• The ability to travel long distances
• The evolution of human diets
• The invention of numbers

If a new fire-starting tool was invented today, what would it need to do to be better than existing methods?

• Be faster and easier to use in different conditions
• Create a fire without needing fuel
• Remove oxygen instead of adding it
• Work only in controlled environments
• Only produce blue flames for safety reasons

What would happen if fire had no flash point?

• Fire would start burning instantly in any condition
• Fire would never burn because no vapors would ignite
• Fire would spread randomly in all directions
• Fire would create only heat, not light
• Fire would be completely uncontrollable
