Anatomy of Fire Flashcards
(18 cards)
Self sustaining process of rapid oxidation of a fuel being reduced by an OA
Combustion
Example of very slow oxidation
Rusting
Example of very fast oxidation
detonations and Explosions
Components of Fire
Heat, Oxygen, Fuel and Chain reaction
Materials that yield oxygen during chemical reaction
Oxidizing Agents
material or substance being oxidized
Fuel
condition of matter in motion caused by the movement of molecules.
* laging meron because mlecules move all the time; higher movement = increase in temperature
Heat
Conduction - direct contact, Convection - movement of air or liquid and Radiation - travels through a material or space
Heat Transfer
Reducing of Temperature - cooling with water,
Eliminating of fuel - allow to be consumed fully, or physical removal of fuel,
Removal of Oxygen - reduction of oxygen concentration
Fire Extinguish Theory
Types of Extinguisher

Types of Fire Extinguisher
Self Expellant, Stored Pressure
OPERATE A FIRE EXTINGUISHER
T – Twist the pin P – Pull the pin A – Aim the nozzle at the base of the fire S – Squeeze the Operating Lever S – Sweep from side to side
