Fire Basics
This is the visible result of combustion
Fire
What stage of fire is more independent on the environment in the compartment.
Growth
This method of heat transfer occurs when solids are in direct contact
Conduction
This class involves flammable or combustible liquids like gasoline.
What extinguishment type can we use for this fire?
Class B
Shutting off the fuel, foam to exclude the oxygen
This is the attribute of smoke that indicates the amount of fuel being heated.
Volume
What are the components for the fire triangle?
Fuel
Oxygen
Heat
Which stage of fire is easiest to extinguish with a fire extinguisher?
Incipient Stage
This form of heat transfer occurs in fluids and gases through movement
Convection
Fires involving ordinary solid combustibles, like wood and paper, belong to this class
What extinguishment type can we use for this fire?
Class A
Cool the fuels with water
The speed of smoke indicates how much pressure is inside a building. This is called?
Velocity
What are the components of the fire tetrahedron?
Fuel
Oxygen
Heat
Chemical Chain Reaction
This stage of fire is when the fire has met it maximum heart release rate (HRR).
Fully developed stage
This type of heat transfer involves electromagnetic waves
Radiation
Fires that involve energized electrical equipment fall into this category.
What extinguishment type can we use for this fire?
Class C
Extinguishing agents that do not conduct electricity, turn off the electricity
This attribute shows how much fuel is in the smoke.
Density
What are the states of matter that can be fuels? Which state burns?
Solid, liquid, gas
Gas (vapors) combust
This is the stage of fire where the fire may be pyrolyzed the fuels and the rate of combustion will decrease.
Decay Stage
The measure of heat transfer from one surface to another is called
Heat Flux
Fires that involve combustible metals such as zinc and magnesium
What extinguishment type can we use for this fire?
Class D
Smoother the fire, exclude oxygen, foam
Smoke that is high in volume, high-velocity, ultra-dense, and turbulent is referred to as this.
Black Fire
What is the reaction occurs when oxygen combines with a substance and produces heat
Oxidation
What is a spontaneous ignition of hot gasses in the upper levels of the room.
What is the rapid transition from a fire that is growing by igniting all fuels available.
Rollover/flameover
Flashover
What is the rate measures how fast heat energy is generated in a fire
Heat Release Rate (HRR)
Fires that involve combustible cooking oils
What extinguishment type can we use for this fire?
Class K
Extinguishing agent that contain a wet agent and can combine with the cooking oil to make a soap like substance
This smoke's ______ can indicate a fire's stage or specific materials burning.
What _____ is produced when a fire is primarily burring wood?
color
White
