Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), is a flamable mixture of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.

Varieties of LPG bought and sold include mixes that are mostly propane (C3H8), mostly butane (C4H10), and, most commonly, mixes including both propane and butane. In the northern hemisphere winter, the mixes contain more propane, while in summer, they contain more butane.

LPG is used for cooking in many countries for economic reasons, for convenience or because it is the preferred fuel source.

In India, nearly 8.9 million tons of LPG was consumed in the six months between April and September 2016 in the domestic sector, mainly for cooking. The number of domestic connections are 215 million (i.e., one connection for every six people) with a circulation of more than 350 million LPG cylinders. Most of the LPG requirement is imported. Piped city gas supply in India is not yet developed on major scale. LPG is subsidised by the Indian government for domestic users. Increase in LPG prices has been a politically sensitive matter in India as it potentially affects the middle class voting pattern.

Never keep the LPG cylinder in your cabinet.

The LPG stove should always be fitted on kitchenette slab at a position above cylinder.

The cylinder should be kept as far as possible other heat sources like induction cooker, lit lamp etc.

Turn the regulator knob to 'OFF' position once you are done with cooking.

LPG cylinder can blast if it is continuously kept exposed to immense heat or fire. In houses, LPG cylinder will not just get blasted on its own. first there will b a LPG leak from the O ring/ faulty regulator or leaky cylinder 

A gas burner is a device that produces a controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and combustion. The flame is generally used for the heat, infrared radiation, or visible light it produces.

Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper. In other areas, the use of copper is widespread.

A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid

A gas regulator reduces the high pressure from the gas bottle to a consistent regulator gas pressure, as required by the application. Gas regulators are used for all compressed gases and gases liquefied under pressure, like LPG gas regulators for LPG bottles
