1. ORIGIN OF FIRE: 1.1. The tetrahedron-FIRE: It says that to occur it is necessary to fire a chemical reaction between a fuel and an oxidizer and has an activation energy and that three factors make up the triangle of fire. And the fire tetrahedron is formed with the above plus the chain reaction is one that does not need external energy to maintain. # Fuel: Something that reacts easily with an oxidizer to produce heat. # Oxidising: What activates the fuel (oxygen). # Energ Activation: The minimum energy required for the combustion process. Chain Reaction #: Do not need external power to maintain itself. TYPES OF FIRE: # Fuel: Solid-Wood "A" / Liquid-Gas "B" Oil-Acetylene "C" / Metal / Sodium "D". # Electrical: Short, burn "D".

2.1. ELIMINATION OF Tetrahedron: It turns off if we remove any of its components. OXIDIZING @ # Suffocation: prevent oxygen from entering the fire zone. # Modification: Changing the air by an atmosphere of inert CO2 displacing oxygen. # E. ACTIVATION: # Cooling: Heat is to eliminate substances thrown into the fire by decomposition or change of state to absorb energy. # FUEL: Avoid cutting off fuel to continue burning for the key step or pump. # R. CHAIN: After the first combustion particles avoid the following burn (eg flame retardant).

2.2. Extinguishing Media: Substance that incinerate act on one or more points. # Water (cooling) # dry ice: Compressed gas that absorbs much heat to make the change of state (Smothering and cooling). # Foam Physics: Bubbles , water and a foaming agent (suffocation covering the fuel and preventing the entry of air and cooling at a time). # Powder Dry: Product react in contact with heat leading to other products (cooling, smothering and absorbs free radicals chain reaction). # Halon: Very effective but very clean (broken string consisting of argon). # Aerosols: an alternative method based on creating mists through the sublimation of solid and controlled combustion.

3. FIRE PROTECTION AND PREVENTION: @ structural protection: What we get is separate or secure dangerous areas to reduce fire hazard. @ ALARMS AND DETECTORS: Smoke #: There is current between two plates and a small deviation due to the origin of products combustion decreases current and activates the alarm. # Photoelectric Smoke: Its operation is based on variation suffering brought light to the smoke in its path. # Heat: They act through a bimetal when the temperature increases metal bends and closes the contact to activate. @ FACILITIES: # BIE: Boca Fire Equipped with a hose. # Hydrants: Hydrants water without hose. # Portable Extinguisher: For small fires of less than 2 minutes. No more than 1'70m high. There Terraced Pressure (besides gas) and Internal Pressure. # Sprinklers: They drop the extinguishing agent from above in the form of rain. Humid column are those with constant water pressure and that if it breaks capsule activates the pump for water flows out, they must be replaced once they act. In column have dry detection system, an alarm and then activation.
