Understanding Fire Behavior Concepts

Ranger Katie explains the fire behavior triangle, which includes weather, fuel, and topography as key factors influencing how a fire behaves. She demonstrates how these elements affect fire movement and emphasizes the importance of safety precautions during such demonstrations.

What are the three components of the fire behavior triangle?

• Oxygen, fuel, and heat

• Wind, rain, and humidity

• Weather, fuel, and topography

• Mountains, valleys, and rivers

How does a sunny day affect fire behavior?

• It makes the fire burn slower

• It has no effect on the fire

• It can make the fire burn faster and hotter

• It extinguishes the fire

What is the effect of atmospheric pressure on fire behavior?

• It makes the fire invisible

• It extinguishes the fire

• It can make the fire burn differently

• It has no effect

Which type of fuel is likely to catch fire more easily?

• A clump of pine needles

• A wet log

• A large pine tree

• A stone

What does topography refer to in the context of fire behavior?

• The weather conditions

• The temperature of the fire

• The landscape features like hills and valleys

• The type of fuel available

Why should you not try fire experiments at home?

• They do not provide any learning

• They are too easy to perform

• They require special training and safety precautions

• They are not interesting

What safety equipment is mentioned for fire demonstrations?

• Fire hose

• Fire extinguisher and water

• Fire blanket

• Fireproof suit

How does wind affect fire spread on flat terrain?

• It extinguishes the fire

• It slows down the fire

• It has no effect

• It can push the fire far and fast

What happens to a matchstick fire when there is no wind?

• It burns out quickly

• It changes color

• It spreads rapidly

• It becomes larger

Which factor is NOT part of the fire behavior triangle?

• Weather

• Fuel

• Topography

• Humidity
