LPG : Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), also referred to as simply propane or butane, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan. This substance is added to the gas when it leaves the main storage terminals.

LPG is a mixture of hydrocarbon gases (propane and/or butane) that is liquefied and then used as a fuel. It is non-toxic and non-corrosive, and it burns cleaner than gasoline or diesel and is much more free of particulates when compared to the latter. However, it’s got a lower energy density, with a lower mpg.
LPG concentrations as low as 2% will ignite in air. gas is heavier than air and will travel along floors, downhill into gullies and will settle in low spots, trenches or basements. at high concentrations, gas displaces air to cause asphyxiation. the butane component of LPG has the potential to cause toxic effect
Fire Extinguisher : Sodium bicarbonate, regular or ordinary used on class B and C fires, was the first of the dry chemical agents developed. In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That is, the gas drives oxygen away from the fire, thus stopping the chemical reaction.
The most common method to control a class-A fire is to remove heat by spraying the burning solid fuels with water. Another method of controlling a class-A fire would be to reduce the oxygen content of the atmosphere in the immediate vicinity of the fire (i.e., “smother” the fire), such as by the introduction of an inert gas such as carbon dioxide.
In a fire control includes various techniques such as, widening the fuel ladder, and removing fuel in the fire’s path with firebreaks and backfires to minimize the brush fire reaching new combustible fuel and spreading further.
Fire extinguishers with a Class B rating are effective against flammable liquid fires. These can be fires where cooking liquids, oil, gasoline, kerosene, or paint have become ignited. Two commonly used chemicals are effective in fighting these types of fires.Class-C fires involve electricity as a continuous power source for the ignition of the fuels associated with electrical equipment, such as plastic cable jackets. The application of water does not always result in effective fire control, and there is a general concern regarding conductivity and personnel safety. Class C fires can be effectively controlled by removing the oxygen. The removal of electricity as a continuous ignition source is important to eliminate re-ignition. Once the electricity is removed, the result is a Class A fire. Foam or dry chemical powder can be used to control fires involving shallow liquid spill
