What is fire?
Fire is a chemical reaction among heat, fuel and oxygen with considering of flash point.
Or
Fire is a chemical reaction in which substance (fuel) combines with oxygen making an
exothermic reaction with the emission of light, heat and smoke.
Three things must be present at the same time to Produce fire:
➤ Suitable Oxygen to sustain combustion
➤ Suitable Heat to reach ignition temperature.
➤ Suitable Fuel or combustible material
Together ,they produce the Chemical reaction that is fire.
What is fire Triangle?
Fire safety principle :
Fire extinguishing works on the principle of cutting off the supply of oxygen to the fire and bringing down the temperature.
Fire safety is based upon the principle of keeping fuel sources and ignition sources separate.
Classification of fires:
Fire Extinguishing methods:
There are three methods for fire extinguishing.
1.Smoothering - Cut off oxygen supply
2.Starvation - Remove fuel source
3.Cooling -Cool the materials
Types Of Fire Extinguisher :
There are different types of fire extinguishers for fire extinguishing.
Fire Extinguisher Type VS Fire Class:
ABC Type Fire Extinguisher :
ABC Fire Extinguishers use mono ammonium phosphate, a dry chemical with the ability to quickly put out many different types of fires by smothering the flames.
●This pale, yellow powder can put out all three classes of
fire:
Class A is for trash, wood, and paper
Class B is for flammable liquids
Class C is for flammable gases
Wet Chemical Type Fire Extinguisher:
Wet Chemical Fire Extinguishers contains a solution of potassium which effectively
attacks the flame in two methods.
● Firstly the mist cools the fire and lowers the temperature to stop the fire spreading, also prevents splashing of the hot oils/fat.
For Metal Fire:
Ternary eutectic chloride (TEC) based dry powder is used for extinguishing metal fires.
Ternary eutectic chloride (TEC) based dry powder is specially formulated eutectic mixture of 3 (ternary) salts for metal fires.
It is treated with speciality chemicals to impart flow properties and excellent water repellency.
