Liquefied Petroleum Gas, or LPG as it is better known, is a hydrocarbon. It contains propane, butane, propylene and butylenes. Since it is an inflammable mixture of all these gases, it has to be stored carefully. The various properties of LPG are:-

• It is a good mixture of gases, mainly constituting of Propane and Butane.
• It has a simple structure in chemical terms.
• It is one of the cleanest of all the alternative fuels.
• It is a liquid under normal pressure but at ambient conditions, it is found to be gaseous and in vapor form is two times heavier than air.
• The boiling point of LPG normally ranges anywhere between - 42° to 0°. The boiling point depends at what proportions are Butane and Propane present in the mixture.
• LPG is almost colorless and has to be stored as liquid under pressure. Its weight is about half that of the same volume of water.
• Ethyl Mercaptan is another product which is used to detect LPG leaks. It works like odorant and helps to know when there are LPG leaks.
• LPG's Flash point is - 76° Fahrenheit.
• LPG is essentially a non toxic substance but it can be dangerous if not handled carefully.
• LPG is also known to cause suffocation.
• It is mildly anesthetic and can be harmful if it is found to be present in high proportions. In spite of its anesthetic properties, LPG has never been used or considered safe enough for medicinal purposes.
• The ignition temperature of LPG is found to be in the range of 410° to 580° Celsius.
• It is also known that liquid LPG has resulted in cold burns to human skin since it causes vaporization at a very fast rate.
