Energy
Known as an exothermic reaction.
What is oxidation?
When the temperature is high enough to vaporize the fuel.
When does a liquid burn?
Conduction, Radiation, and Convection
What are the 3 mechanisms of heat transfer?
Petroleum based accelerants.
What are most arsons started with?
New paint cans or wide mouth glass jars.
What should you store fire scene evidence in?
The heat and light released when a substance burns.
Burning located at the fuel air interface.
What is glowing combustion? OR What is smoldering?
The movement of heat through a solid object.
What is conduction?
The most common ignitor.
1. A fuel must be present.
2. Oxygen must be available in a sufficient quantity.
3. Heat must be applied.
What are required to initiate and sustain a fire?
Cigarettes, embers of wood fire, or a charcoal fire.
The transfer of heat energy by electromagnetic radiation.
What is radiation?
An irregular shaped pattern on the floor.
What is a sign of arson?
This gets injected into the gas chromatograph in order to separate its components.
What is vapor?
869 degrees Fahrenheit
What is the ignition temperature for acetone?
The lowest temperature at which a liquid produces enough vapor to burn.
What is the flash point?
The transfer of heat energy by the movement within a liquid or gas.
What is convection?
Occurs when all the combustible fuels simultaneously ignite to engulf the entire structure.
What is a flashover?
The gas chromatograph separates these components of the vapor.
What is hydrocarbon?
19,550 Btu/lb
What is the heat of combustion for diesel fuel?
When something burns only when exposed to heat that is hot enought to decompose it into gaseous products.
What is pyrolysis?
What is convection?
The search for traces of flammable liquid residues may be aided by this device.
What is a sensitive portable vapor detector?
The speed of decomposition in a low explosive.
What is deflagration?
