Reactions that result in the release of heat energy
What is Exothermic
100
Airborne products of combustion consisting of; particles, vapors and gasses
What is Smoke
100
Fires that are fully or partially contained within a building
What is An Interior Structure Fire
100
Fuel and air mixture within flammable limits, and ignition source and enough sustained contact between the ignition source and the fuel to air mixture in order to transfer the ignition energy are three characteristics of a
What is Liquid Fire
100
Ignition, Growth, Fully Developed and Decay
What is The four Phases of Fire
200
Reactions that absorb heat or require heat to be added
What is Endothermic
200
Solid matter consisting of unburned, partially burned or completely burned substances
What is Particles
200
Fires that burn only these and not the structure itself.
What is Room Contents.
-Modern rooms contain many plastic and synthetic materials
-Wall and ceiling finishes can burn readily.
200
The lowest temperature that a liquid produces vapor
What is Flash Point
200
When temperature in a room reach 1000 degrees Fahrenheit because all combustible material ignites at once.
What is Flashover
300
Chemically combining oxygen with another substance to create a new compound
What is Oxidation
300
Small droplets of liquids suspended in air such as oils from fuel or water due to suppression effortts
What is Vapors
300
The total quantity of combustibles in a room
What is Fuel Load
-Determines how much heat and some will be generated
-Size, shape and arrangement of fuel will affect combustibility and fire spread.
300
The lowest Temperature at which a liquid produces enough vapor to support a small flame for a short period of time
What is Flame Point (or Fire Point)
300
The phase when the fire is slowing down and running low on or completely out of fuel
What is The Decay Phaze
400
Rapid self sustaining process that combines oxygen with another substance and results in a release of heat and light
What is Combustion
400
Carbon monoxide, hydrogen cyanide and phosgene are these most common byproducts of fire.
What is Gases
400
Flashover, flameover (or roll over), backdraft, thermal layering and thermal balance
What is Special Considerations
-Four conditions particular to interior fires that affect firefighter and civilian safety.
400
The temperature at which the fuel air mixture will spontaneously ignite.
What is Ignition Temperature
400
The phase of fire where heat is produced at a maximum rate, oxygen is consumed rapidly and the fire will burn as long as fuel and oxygen are present.
What is The Fully Developed Phase
500
Decomposition of a material caused by external heating
What is Pyrolysis
500
Conduction, Convection and Radiation are all examples of
What is Heat Transfer
500
Little to no visible flame, smoke emanating under pressure from cracks, unexplained change in color of smoke, signs of extreme heat and glass is smoke stained or blackened are all characteristics of this impending special condition
What is Backdraft
500
Occurs when a tank storing liquid fuel under pressure is heated excessively.
What is BLEVE-Boiling Liquid Expanding Vapor Explosion
500
As more fuel is ignited the fire grows larger, convictions currents draw more air to the fire, hot gases collect at the ceiling and begin to bank downward, the fire will continue to grow as long as oxygen and fuel are present.
