Fire Mitigation

There are 3 ( three ) ways to overcome / extinguishing fires :

Decomposition method that is way off to separate or keep materials / objects that can catch fire
How to put out a fire that is cooling to lower the heat or temperature . Water is the most dominant material used in hot down the street squirt or pour water onto a fire point .
How Insulation / localization that is the way to reduce the rate of fire fighting / percentage of O2 in the things that burn.

Materials Fire Extinguishing Materials that many found and used at this time include:
Extinguishing media Water
Extinguishing foam ( Foam )
CO2 extinguishing
Material dry powder extinguishers ( Dry chemical )
Gas extinguishing Halon (BCF )

Extinguishing media Water
Extinguishing water is easily available , cheap price, can be used in an endless number does not even have to buy / free. Water and lowering heat / temperature ( cooling ) can also resist / reject and expel the oxygen inclusion when atomized.

At this time fire extinguishing water used with lite / form fog ( Fog ), because it has several advantages compared with the emission of water include:

Having the ability to absorb heat ( cooling ) is greater . 1 liter of water to absorb heat emitted 30 kcal , whereas when atomized 1 liter of water can become steam of 1.600 Lt. and will absorb heat to 300 kcal .
Nozzel spraying more manageable , by arranging nozzel beam can be operated even lite mist ( fog )
Fresh air

Can be used on an oil fire ( liquid substances )


Gains and losses of water :

Advantages:
1 . well as cooling medium
2 . easily available and a large number
3 . low exploitation costs

losses :
1 . transmit power
2 . use on ships can disrupt the balance ( stability )
3 . can damage your valuables such as electronic devices
4 . add hot when exposed carbide raw copra , or certain chemical substances

Extinguishing foam ( Foam )

Effective foam extinguishing class B fires ( oil , diesel and liquid ) , to put out the fire bendapadat (Class A) less good , As is known that firefighters with foam material is insulating manner that is preventing the entry of air in the fire ( fire ) , with cover / envelop the surface of things burns up fuel does not flow .

According to the manufacturing process there are two types of foam that is:
Chemical foam ( Chemis )
Mechanical foam , less foam is sprayed on the surface correspond to a simple liquid is mixed with water ( Alcohol , spirtus ) because the foam is easily soluble in water


CO2 extinguishing

Fire extinguishing CO2 or carbon dioxide gas and can be used to extinguish all types of fire, especially in class C. The blow will be able to expel CO2 and reducing the percentage of oxygen ( O2 ) that is in the air up to 12 % - 15 % - CO2 gas is heavier from the air and other gases such as not sending power , no smell and no residue / clean .


Deletion of flour ( powder ) Dry chemical ( drychemical )

Dry chemical can be used for all types of fires , not harmful to human / animal because it is non-toxic ,

Materials referred to as a dry chemical fire extinguisher that works double ( multi purpose extinguishers )
Not sending electric Powder oxygen binding function ( insulation ) and can also bind other gases that are harmful. Can lower the temperature, Easy to clean and do not break the tools.

How dry chemical usage is very similar to the CO2 gas which is as follows :
First it should be noted there / the wind , if the wind blows too strong, use dry chemical is not efficient .
Direct emissions and flame cutters can earn formed a sort of cloud / smoke to cover the fire .

Gas extinguishing Halon (BCF )
Fire Extinguisher Lighter types of Halon 1211 (BCF / Carbon, Flourine , Chlorine , Bromide ) .
Halon 1211 (BCF ) is usually mounted on the walls of the office in the form of Light Fire Extinguisher ( APAR ) and effectively used in the space , because the nature of fire fighting mengisolir oxygen , while the halon gas is very good because it is not a destructive nature and clean.
