10

Factors that affect the rate in which a fire will grow include all of the following except ____?

The ambient temperature outside the fire area

11

Name the fire phase described: Fire is affected by the amount of oxygen, fuel, space, and insulation of the ceilings and walls.

Growth

12

Name the fire phase described: Fire is virtually free burning and has plenty of fuel?

Fully developed

13

Name the fire phase described: Fuel package has been mostly consumed and heat release rate drops.

Decay

14

Name the fire phase described: Heat generated from the ignition now begins to cause heat transfer to surrounding combustibles.
