Its a rough flame, unsteady, irregular swirls
TURBULENT FLAME
11
The manner which the fuel ignites, flame develops, and fire spreads distinguish characteristics of one particular fire from typical fire characteristics
FIRE BEHAVIOR
12
any substance/combustibles that reacts chemically with oxygen and produces flames. For a fire to start there must be something to burn
FUEL
13
An energy created by friction and compression.
MECHANICAL ENERGY
14
A gas which can be fatal after only a few breaths
HYDROGEN CHLORIDE
15
material or substance being burned in the combustion process. The fuel in a combustion reaction is known as
REDUCING AGENT
16
A smooth path through a gaseous flame
LAMINAR FLAME
17
Fire spreads along trough a burning material by flame contact
DIRECT FLAME CONTACT
18
A visible radiation created at the atomic level such as flame produced during combustion.

21
colorless and odorless gas and one of the compositions of air that supports fire
OXYGEN
22
A fire gas formed during involving organic material
HYDROGEN SULFIDE
23
material/substance that yields or provides oxygen or oxidizing gases needed during a chemical reaction
OXIDIZING AGENT
24
Orange yellow
1100*c
25
Unhibited chain reactions are interrupted
CHAIN BREAKING
26
The fire triangle theory describes the three elements of a fire combustion uses a four sided figure called
FIRE TETRAHEDRON
27
Is a rapid fire self sustaining oxidation process release of heat and light
FIRE
28
its direct contact with heated object
CONDUCTION
29
Smoke and gases that are generated by the combustion are confined fires that start in a confined building, go through an additional phase called?
FLASHOVER
30
Blue flames
1400-1650*c
31
The growth phase called
INCIPIENT STAGE
32
The initial source to other fuels in and beyond the area of fire origin
TRANSMISSION OF HEAT
33
Occurs when the fire heats the air near
CONVECTION
34
Is the three elements to create produce fire equal in proportion
FIRE TRIANGLE THEORY
35
This process is necessary for continuous combustion. The continuous collisions of molecules in the reducing and oxidizing agents create thermal energy which sustains the combustion process.
SELF SUSTAINED CHEMICAL REACTION
36
It is thermal decomposition of solid fuel through the action of heat called?
PYROLYSIS
37
heat is generated when a gas is compressed in a container or cylinder
HEAT OF COMPRESSION
38
A causes solid and liquid fuels and the.production of ignitable vapours or gases
PYROLYSIS OR VAPORIZATION
39
Known as the chemical chain reaction
FIRE TETRAHEDRON THEORY
40
A visible product of incomplete combustion a mixture oxygen, particles released from the burning material

Specifies that tends to flow from a hot substance to cold substance
LAW OF HEAT FLOW
42
The fully developed stage
FREE BURNING STAGE
43
Its is lowered to a point where burning will stop

44
Stages or steps wherein fir e is created
LIFE CYCLE OF FIRE THEORY
45
