FIRE INVESTIGATOR – TCFP Exam
questions 100% correct, expert
verified answers
3 TYPES OF RADIATION alpha, beta, gamma
ALPHA RADIATION BOUNCES OFF CLOTHING
BETA RADIATION PENETRATES CLOTHING
GAMMA RADIATION PENETRATES CLOTHING AND SKIN
PARTS OF HAZMAT PLACARD YELLOW - INSTABILITY
RED - FLAMMABILITY
BLUE - HEALTH
OXIDATION CHEMICAL REACTION INVOLVING THE COMBINATION OF OXYGEN WITH OTHER
MATERIALS
EXOTHERMIC Chemical Reaction in which energy is primarily given off in the form of heat
ENDOTHERMIC (of a chemical reaction or compound) occurring or formed with absorption of
heat
FIRE IS AN EXOTHERMIC REACTION CALLED: COMBUSTION
COMBUSTION RELEASES ENERGY IN THE FORM OF: HEAT OR LIGHT
,PILOTED IGNITION MOMENT WHEN A MIXTURE OF FUEL AND OXYGEN ENCOUNTER AN
EXTERNAL HEAT SOURCE WITH SUFFICIENT HEAD ENERGY TO START THE COMBUSTION REACTION.
AUTOIGNITION Occurs without any external flame or spark to ignite the fuel gases or vapors
POTENTIAL ENERGY ENERGY POSSESSED BY AN OBJECT THAT MAY BE RELEASED
KINETIC ENERGY ENERGY POSSESSED BY A MOVING OBJECT
BTU British Thermal Unit
BTU IS USED TO MEASURE: HEAT
RESISTANCE HEATING WHEN ELECTRICAL CURRENT FLOWS THROUGH A CONDUCTOR, HEAT IS
PRODUCED
OVERCURRENT WHEN THE CURRENT FLOWING THROUGH A CONDUCTOR EXCEEDS ITS DESIGN
LIMITS.
ARCING High-temperature luminous electric discharge across a gap or through a medium such as
charred insulation.
SPARKING WHEN AN ELECTRIC ARC OCCURS LUMINOUS PARTICLES CAN BE FORMED AND
SPATTER AWAY FROM THE POINT OF ARCING.
CONDUCTION The direct transfer of heat from one substance to another substance that it is
touching.
CONVECTION TRANSFER OF HEAT ENERGY FROM A FLUID TO A SOLID SURFACE OR BETWEEN
TWO FLUIDS.
, RADIATION TRANSMISSION OF ENERGY AS AN ELECTROMAGNETIC WAVE
FUEL CONTROLLED FIRE FIRE LIMITED BY THE AMOUNT OF COMBUSTIBLES
VENTILATION CONTROLLED FIRE FIRE LIMITED BY THE AMOUNT OF OXYGEN
STAGES OF FIRE GROWTH ignition, growth, flashover, fully developed, decay
FLASHOVER A transition phase in the development of a compartment fire in which surfaces
exposed to thermal radiation reach ignition temperature more or less simultaneously and fire spreads
rapidly throughout the space, resulting in full room involvement or total involvement of the
compartment or enclosed space.
FACTORS THAT INFLUENCE FLASHOVER CONDITIONS: SIZE OF COMPARTMENT, HEIGHT OF
CEILING, VENTILATION, AMOUNT OF FUEL, LAYOUT OF FUEL, LOCATION OF FIRE IN COMPARTMENT
FIRE PATTERNS PHYSICAL MANIFESTATION OF THE AFFECTS OF FIRE ON MATERIALS
TYPES OF FIRE PATTERS ON THE WALLS & CEILING: PLUME GENERATED, VENTILATION
GENERATED AND HOT GAS LAYER PATTERNS
PLUME GENERATED PATTERS ARE: V SHAPE
SPALLING SEPARATION OF CHUNKS OF CONCRETE WITHIN EXPLOSIVE FORCE CAUSE BY
EXPANSION OF WATER TRAPPED IN THE CONCRETE AS IT TURNS TO STEAM.
CHAR PYROLIZED CARBONACEOUS MATERIAL
ALLOYING MIXING TWO METALS HEATED THEN COOLED TO CHANGE THEIR PROPERTIES.
