Chapter 14 Flashcards
Accelerant
A compound that facilitates the initiation and/or growth of a fire.
Flashover
The rapid transition to a fully developed fire by the nearly simultaneous ignition of all
Backdraft
When a fire burns in an enclosed space and uses up much of its oxygen supply, starving the fire of oxygen and then oxygen is rapidly reintroduced to the room that has accumulated unburned fuel, often producing an explosion.

Black Powder
a mixture of potassium nitrate, carbon and sulfur (usually in a 75:15:10 ratio) that burns very rapidly upon ignition.
Brisance
The shattering power of a shock wave.
Detonation
Very rapid oxidation reaction generated by high explosives that produces highly destructive supersonic pressure waves.
Exothermic Reaction
A chemical reaction that liberates heat.
Fire
The rapid oxidation of substances through combustion reactions with the evolution of energy, often in the form of heat and light, and the formation of chemical products.
Dynamite
A mixture of an adsorbent, such as diatomaceous earth, sawdust, clay or wood pulp, that has been soaked in nitroglycerin. a stable explosive

Flashover
The rapid transition to a fully developed fire by the nearly simultaneous ignition of all the flammable materials in an enclosed space.

Chemical explosive
A chemical that undergoes an extremely rapid chemical reaction that releases both kinetic and thermal energy.
Combustion
The rapid oxidation of a compound where a fuel reacts with an oxidant to form new compounds formed of each element in the fuel combined with the oxidant, and the generation of heat and light.
