Stages of Fire
Stage of fire where energy release is at a maximum and is only limited by availability of fuel and oxygen.
What is FULLY DEVELOPED?
BURNING COOKING OILS AND FATS IN A KITCHEN
What is a CLASS K Fire?
Instantaneous explosion of super-heated gases that occurs when oxygen is introduced into an oxygen depleted confined space.
What is a BACKDRAFT?
Four Products of Combustion?
What is heat, smoke, gases, and light
A RAPID CHEMICAL PROCESS THAT PRODUCES HEAT AND LIGHT
What is Fire
The early stage of a fire where fuel and oxygen are virtually unlimited.
What is the GROWTH STAGE?
THIS FIRE INVOLVES COMBUSTIBLE METALS SUCH AS SODIUM, MAGNESIUM, AND TITANIUM
What is a CLASS D Fire?
Condition in which unburned gases traveling along the ceiling mix with oxygen and ignite, spreading rapidly across the ceiling.
What is ROLLOVER?
WHAT ARE THE 3 FORMS OF MATTER
SOLID, LIQUID, AND GAS
A CHEMICAL REACTION UNITES FUEL, HEAT, AND OXYGEN IN THIS FIRE TRIANGLE
WHAT IS THE FIRE TETRAHEDRON
Stage of fire when fuel is consumed and energy release diminishes. Fire goes from vent controlled to fuel controlled.
What is DECAY STAGE?
THIS FIRE INVOLVES ENERGIZED ELECTRICAL EQUIPMENT
What is a CLASS C Fire?
THE MOVEMENT OF HEAT AND SMOKE FROM THE FIRE AREA TOWARDS THE LOWER PRESSURE AREA ACCESSIBLE VIA DOORS AND WINDOW OPENINGS
WHAT IS FLOW PATH
HEAT SPREADS VIA THESE METHODS
WHAT IS CONDUCTION, CONVENTION, RADIATION
What is the fire triangle
Heat, Fuel, Oxygen
Stage of fire marked by ignition.
What is INCIPIENT STAGE?
Gasoline, oils, alcohol, and propane are considered what type of Fire?
What is Class B
Condition in which all surfaces and objects reach their ignition temperature and flames break out at once over the surface of all objects in the space.
What is a FLASHOVER?
What is PPV?
Positive Pressure Ventilation
THIS OCCURS WHEN A FLAMMABLE LIQUID IS STORED UNDER PRESSURE AND THE CONTAINER FAILS IN A FIRE
What is a BLEVE?
Solids become gasses through this process?
What is pyrolysis
BURNING ORDINARY COMBUSTIBLES SUCH AS PAPER AND WOOD
What is a CLASS A Fire?
THE TENDENCY OF FIRE GASES IN AN ENCLOSED SPACE TO FORM LAYERS ACCORDING TO THEIR TEMPERATURE
WHAT IS THERMAL LAYERING
The measure of heat energy in the customary system
BTU British Thermal Unit
THE LOWEST TEMPERATURE AT WHICH A SUBSTANCE RELEASES ENOUGH VAPOR TO IGNITE AND SUSTAIN COMBUSTION
What is Fash Point
