Cooking gas also known as LPG (liquefied petroleum gas) is a source of energy used for cooking, heating and lightning. Cooking gas is a colorless and odorless gas.
However, a special odor has been intentionally added so that a potential leak can be detected easily.
Cooking gas is produced by refining crude oil in refineries or from natural gas and delivered to the consumers in steel tanks. LPG, which is heavier than air due to its high density, is a hydrocarbon-based combustible gas.
