Chapter 11: Forensic Aspects of Arson and Explosion Investigations
Any material used to start or sustain a fire. The most common accelerants are combustible liquids.
Normally, a mixture of potassium nitrate, carbon, and sulfur in the ratio 75/15/10.
Rapid combination of oxygen with another substance accompained by the production of noticeable heat and light.
A very rapid oxidation reaction accompanied by the generation of a low-intensity pressure wave that can disrupt the surroundings.
A cordlike explosive containg a core of high-explosive material, usually PETN; also called primacord.
An extremely rapid oxidation reaction accompanied by a violent disruptive effect and an intense, high-speed shock wave.
A chemical transformation in which heat energy absorbed from the surroundings.
The combine ability or potential of a system or material to do work. Some forms of energy are heat energy, chemical energy, and electrical energy.
A chemical transformation in which heat energy is liberated.
A chemical or mechanical action resulting in the rapid expansion of gases.
The entire range of possible gas or vapor fuel concentrations in air that are capable of burning.
The minimum temperature at which a liquid fuel produces enough vapor to burn.
Burning at the fuel-air interface. Examples are a red-hot charcoal or a burning cigarette.
Heat of Combustion
The heat liberated during combustion.
An explosive with a velocity of detonation greater than 1,000 meters per second. Examples include dynamite and RDX.
Any compound consisting only of carbon and hydrogen.
The minimum temperature at which a fuel will spontaneously ignite.
An explosive with a velocity of detonation less than 1,000 meters per second. Examples include black powder and smokeless powder.
An offender's pattern of operation.
The combination of oxygen with other substances to produce new substances.
A substance that supplies oxygen to a chemical reaction.
A high explosive that is easily detonated by heat or shock.
The decomposition of organic mattery by heat.
A cord containing a core of black powder. It is used to carry a flame at a uniform rate to an explosive charge.
A high explosive that normally must be detonated by a primary explosive.
Smokeless Powder ( Double-base)
An explosive consisting of a mixture of nitrocellulose and nitroglycerin.
Smokeless Powder (Single-base)
An explosive consisting of nitrocellulose.
A fire caused by a natural heat-producing process in the presence of sufficient air and fuel.
