4 General Categories Of Heat Energy

Chemical Heat Energy

Electrical Heat Energy

Mechanical Heat Energy

Nuclear Heat Energy

Backdraft - a phenomenon in which a fire that has consumed all available

oxygen suddenly explodes when more oxygen is made available, typically

because a door or window has been opened.

Boiling Point - The temperature of a substancewhere the rate of

evaporation exceeds the rate of condensation.

British Thermal Unit - (BTU) The amount of heat needed to raise thetemperature of one pound of waterone degree F.

Calorie - The amount of heat needed to raise the temperature of one

gram of water one degree Centigrade.

Centigrade - (Celcius) On the Centigrade scale, zero is the melting

point of ice; 100 degrees is the boiling point of water.

Chemical Heat Energy

Heat of Combustion - The amount of heat generated by the

combustion (oxidation) process.

Heat of Decomposition - The release of heat from decomposingcompounds. These compounds may be unstable and release

their heat very quickly or they may detonate.

Heat of Solution - The heatreleased by the mixtureof matter

in a liquid. Some acids, when dissolved, give off sufficient

heat to pose exposure problems to nearby combustibles.

Spontaneous Heating - The heatingof an organic substance

without the addition of external heat. Spontaneous heating

occurs most frequently where sufficient air is not present

to dissipate the heat produced. The speed of a heating

reaction doubles with each 180 F (80 C) temperature increase.

Classification of Fires

Class A Fire - Fires involving ordinary combustible materials,

such as wood, cloth, paper, rubber and many plastics.

Class B Fires - Fires involving flammable liquids, greases

and gases.

Class C Fires - Fires involving energized electrical equipment.


2/10

Class D Fires - Fires involving combustible metals, such as

magnesium, titanium, zirconium, sodium and potassium.

Class K Fires - Class K is a new classification of fire as

of 1998 and involves fires in combustible cooking fuels such

as vegetable or animal fats.

Combustion- is the self-sustaining process of rapid oxidation of a

fuel being reduced by an oxidizing agent along with the evolution of

heat and light.

Dry Chemicals and Halons- method of fire extinguishment, interrupt

the flame producing chemical reaction, resulting in rapid extinguishment.

Electrical Heat Energy

Dielectric Heating - The heating that results from the action

of either pulsating direct current, or alternating current

at high frequency on a non-conductive material.

Heat from Arcing - Heat released either as a high-temperature

arc or as molten material from the conductor.

Heat Generated by Lightning - The heat generated by the

discharged of thousands of volts from either earth to cloud,

cloud to cloud or from cloud to ground.

Induction Heating - The heating of materials resulting from

an alternating current flow causing a magnetic field influence.

Leakage Current Heating - The heat resulting from imperfect

or improperly insulated electrical materials. This is

particularly evident where the insulation is required to

handle high voltage or loads near maximum capacity.

Resistance Heating - The heat generated by passing an

electrical force through a conductor such as a wire or

an appliance.

Static Electricity Heating - Heat released as an arc between

oppositely charged surfaces. Static electricity can be

generated by the contact and separation of charged surfaces

or by fluids flowing through pipes.

Endothermic Heat Reaction - A chemical reaction where a substance

absorbs heat energy.

Exothermic Heat Reaction- A chemical reaction where a substance

gives off heat energy.

Fahrenheit- On the Fahrenheit scale, 32 degrees is the melting point

of ice; 212 degrees is the boiling point of water.

Fire point - The temperature at which a liquid fuel will produce

vapors sufficient to support combustion once ignited. The fire point

is usually a few degrees above the flash point.

on human resource developmentof all personnel of the Bureau of Fire

Protection (BFP).

Flame- A gas-phased combustion.

Flammable or Explosive Limit - The percentage of a substance in air

that will burn once it is ignited. Most substances have an upper

(too rich) and a lower (too lean) flammable limit.

Flashover- an instance of a fire spreading very rapidly across a gap

because of intense heat. Occurs when a room or other area becomes

heated to the point where flames flash over the entire surface or area.

Flash Point - The minimum temperature at which a liquid fuel gives

off sufficient vapors to form an ignitable mixture with the air near

the surface. At this temperature, the ignited vapors will flash, but

will not continue to burn.

Fuel- is the material or substance being oxidized or burned in the

combustion process. Material such as coal, gas, or oil that is burned

to produce heat or power.

Fuel Removal - method of fire extinguishment, fire is effectively

extinguished by removing the fuel source. This may be accomplished by

stopping the flow of liquid or gaseous fuel or by removing solid fuel

in the path of the fire or allow the fire to burn until all fuel

is consumed.

Glowing Combustion- A condensed phased combustion.

Heat - the quality of being hot; high temperature. A form of energyarising from the random motion of the molecules of bodies, which

may be transferred by conduction, convection, or radiation.

Heating - is transfer of energy, from a hotter body to a colder one,

other than by work or transfer of matter.

Heat of Combustion- The amount of heat generated by the combustion

(oxidation) process.

Heat Transfer

Conduction - Conduction is the transfer of energy through

matter from particleto particle. Heat may be conducted from

one body to another by direct contact of the two bodies or

by an intervening heat-conducting medium.

Convection - is the transfer of heat by the actual movement

of the warmed matter. Transfer of heat by the movement of

air or liquid.

Radiation - Electromagneticwaves that directly transport

energy through space.


4/10

Ignition Temperature - The minimum temperature to which a fuel in air

must be heated in order to start self-sustained combustion independent

of the heating source.

Heat - The form of energy that raises temperature. Heat is measured

by the amount of work it does.

Heat of Decomposition- The release of heat from decomposing compounds.

These compounds may be unstable and release their heat very quickly or

they may detonate.

Heat of Solution - The heat released by the mixture of matter in a

liquid. Some acids, when dissolved, give off sufficient heat to pose

exposure problems to nearby combustibles.

Mechanical Heat Energy

two objects in contact with each other.

Friction Sparks - The heat generated in the form of sparks

from solid objects striking each other. Most often at least

one of the objects is metal.

Heat of Compression - The heat generated by the forced

reduction of a gaseous volume. Diesel engines ignite fuel

vapor without a spark plug by the use of this principle.

Nuclear Fission and Fusion - The heat generated by either the

splitting or combining of atoms.

Oxidation- The complex chemical reaction of organic material with

oxygen or other oxidizing agents in the formation of more stable

compounds.

Oxidizing Agents - are those materials that yield oxygen or other

oxidizing gases during the course of a chemical reaction.

the fire area.
