The fire triangle - Answers oxygen - right side
heat -bottom
fuel - left side
Fire Tetrahedron - Answers fuel -top triangle
chemical chain reaction -bottom triangle
heat- bottom left triangle
oxygen - bottom right triangle
Chemical Chain reaction - Answers in the burning process of fuel elements( compounds)are released by
heat produced by the fire. These elements join in the fire (combined with oxygen) to produce more heat
which releases more fuel elements
What is the difference between the fire triangle and the fire tetrahedron? - Answers Chemical chain
reaction
Oxygen percentage in normal air - Answers 21%
Oxygen - Answers supports combustion & life
Minimum percentage of oxygen needed to support respiration & combustion - Answers 16%
visible flame goes out (oxygen) - Answers 15%
Fire goes out (oxygen) - Answers 5%
definition of fire - Answers fire is a rapid chemical combination of fuel and oxygen in the presence of
Heat usually accompanied by production of heat light and combustion byproducts (smoke gases and
dust)
, byproducts of combustion - Answers smoke gases and dust
Fire is usually accompanied by - Answers smoke gases and dust
solid states of fuel -tetrahedron - Answers wood, paper, plastic, rubber
converted into a gas by pyrolysis
size and shape effects ease of ignition and rate of burning
liquid states of fuel - Answers gasoline, kerosene, paint thinner,
vaporization produces gas
flammable or combustible
flammable - vaporization occurs at 99 degrees and below
combustible - vaporization occurs at 100 degrees and above
Gas State of fuel - Answers natural gas LP gas, acetyline,
no conversion necessary
heat - Answers a form of energy that raises temperature. Heat is measured by the amount of work it
does ,for example; the amount of heat needed to make a column of mercury expand inside a glass
thermometer
four sources of heat energy - Answers chemical heat energy
electrical heat energy
mechanical heat energy
nuclear heat energy
