A RAPID CHEMICAL PROCESS THAT PRODUCES HEAT AND USUALLY LIGHT

WHAT IS A FIRE

100
THIS IS A SMALL LOCALIZED FIRE
WHAT IS IGNITION PHASE
100
BURNING COOKING OILS AND FATS IN A KITCHEN
WHAT IS A CLASS K FIRE
100
THE SMALLEST UNIT OF MATTER
WHAT IS AN ATOM
100
THE FIRST STEP IN READING SMOKE IS TO CONSIDER THESE FOUR ATTRIBUTES
WHAT IS SMOKE VOLUME, SMOKE DENSITY, SMOKE VELOCITY, SMOKE COLOR
200

SOLID, LIQUID, AND GAS

WHAT ARE THE 3 FORMS OF MATTER

200
THIS CONDITION DEVELOPS WHEN ADDITIONAL FUEL IS DRAWN INTO THE FIRE
WHAT IS THE GROWTH PHASE
200
THIS FIRE INVOLVES COMBUSTIBLE METALS SUCH AS SODIUM, MAGNESIUM, AND TITANIUM
WHAT IS A CLASS D FIRE
200
A CHEMICAL REACTION UNITES FUEL, HEAT, AND OXYGEN IN THIS FIRE TRIANGLE
WHAT IS THE FIRE TETRAHEDRON
200
SMOKE IS COMPOSED OF THESE THREE MAJOR COMPONENTS
WHAT ARE PARTICLES, VAPORS, AND GASES
300
HEAT SPREADS VIA THESE METHODS
WHAT IS CONDUCTION, CONVENTION, RADIATION, AND DIRECT CONTACT
300
THE TEMPERATURE INCREASES TO THE POINT WHERE FLAMMABLE MATERIAL IN THE ROOM IS UNDERGOING PYROLYSIS
WHAT IS FULLY DEVELOPED PHASE
300
THIS FIRE INVOLVES ENERGIZED ELECTRICAL EQUIPMENT
WHAT IS A CLASS C FIRE
300
IF GAS IS PRESENT IN THE AIR BEYOND THIS MIXTURE LEVEL, IT WILL NOT BURN
WHAT IS UPPER FLAMMABLE LIMIT (UFL)
300
CAUSED BY THE INTRODUCTION OF OXYGEN INTO A CLOSED STRUCTURE WHERE THERE IS A DEFICIENCY OF OXYGEN
WHAT IS A BACKDRAFT
400
ENERGY IS CLASSIFIED INTO THESE FORMS
WHAT IS CHEMICAL, MECHANICAL, ELECTRICAL, LIGHT, AND NUCLEAR
400
TEMPERATURE BECOMES HIGH ENOUGH TO IGNITE ALL THE MATERIALS IN THE ROOM AT ONCE
WHAT IS FLASHOVER
400
FIRE THAT CAN BE EXTINGUISHED BY SHUTTING OFF THE SUPPLY OF FUEL OR BY USING FOAM TO EXCLUDE OXYGEN FROM THE FUEL
WHAT IS CLASS B FIRE
400
THIS OCCURS WHEN A FLAMMABLE LIQUID IS STORED UNDER PRESSURE AND THE CONTAINER FAILS IN A FIRE
WHAT IS A BLEVE
400
SPONTANEOUS IGNITION OF THE HOT GASES IN THE UPPER LEVELS OF A ROOM
WHAT IS FLAMEOVER/ROLLOVER
500
THE PROCESS IN WHICH OXYGEN COMBINES CHEMICALLY WITH ANOTHER SUBSTANCE TO CREATE A NEW COMPOUND
WHAT IS OXIDATION
500
OPEN FLAME BURNING HAS DECREASED AND JUST SMOLDERING FUEL IS PRESENT
WHAT IS THE DECAY PHASE
500
BURNING ORDINARY COMBUSTIBLES SUCH AS PAPER AND WOOD
WHAT IS A CLASS A FIRE
500
THE LOWEST TEMPERATURE AT WHICH A SUBSTANCE RELEASES ENOUGH VAPOR TO IGNITE AND SUSTAIN COMBUSTION
WHAT IS FLAME POINT (FIRE POINT)
500
THE TENDENCY OF FIRE GASES IN AN ENCLOSED SPACE TO FORM LAYERS ACCORDING TO THEIR TEMPERATURE
WHAT IS THERMAL LAYERING
