A fire controlled by characteristics and configuration of fuel.
What is Fuel controlled?
100
Stage of fire where energy release is at a maximum and is only limited by availability of fuel and oxygen.
What is FULLY DEVELOPED?
100
Instantaneous explosion of super-heated gases that occurs when oxygen is introduced into an oxygen depleted confined space.
What is a BACKDRAFT?
100
Temperature range of a flashover.
What is 900-1200 degrees Fahrenheit?
200
Fires that involve combustible liquids.
What is Class B?
200
The four stages of fire.
What is INCIPIENT, GROWTH, FULLY DEVELOPED, and DECAY?
200
The early stage of a fire where fuel and oxygen are virtually unlimited.
What is GROWTH STAGE?
200
Condition in which unburned gases traveling along the ceiling mix with oxygen and ignite, spreading rapidly across the ceiling.
What is ROLLOVER?
200
Signs of impending flashover.
What is thick, dark, turbulent smoke; strong bidirectional airflow; high heat; Rollover
300
Fires that involve oils and greases found in commercial kitchens.
What is Class K?
300
Outcome of combustion in which gases tend to form in layers in a confined space according to temperature.
What is Thermal Layering?
300
Stage of fire when fuel is consumed and energy release diminishes. Fire goes from vent controlled to fuel controlled.
What is DECAY STAGE?
300
Isolated flames scene in the smoke above the neutral plane circling the outer edge of the smoke plume.
What is GHOSTING?
300
Radiant heat from a flashover is only survivable for this long.
What is a few seconds?
400
Fires that involve normal combustible materials.
What is Class A?
400
Fire that is limited in growth by the amount of available air supply.
What is ventilation controlled?
400
Stage of fire marked by ignition.
What is INCIPIENT STAGE?
400
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?
400
Correlates to the temperature of 1,128 degrees Fahrenheit
What is the autoignition temperature of carbon monoxide?
500
Fires that involve combustible metals.
What is Class D?
500
The total amount of fuel available for combustion.
What is Fuel Load?
500
The stage at which a fire first moves from fuel controlled to ventilation controlled.
What is GROWTH STAGE?
500
Little visible flame, dense grey-yellow smoke, smoke exiting in puffs, and inwardly drawn smoke are signs.
What is an IMPENDING BACKDRAFT?
500
The best way to survive a flashover.
What is don't get caught in one by recognizing the signs, and your surrounding environment?
