Uses: Propane is used as fuel for cars and as a propellant in gas bottles such as propane cylinders and as a propellant in aerosol sprays such as deodorants.
Very pure forms of butane, especially iso-butane, can be used as refrigerants and have largely replaced the halomethanes, for instance in household refrigerators and freezers.
However, should there be an oxygen-deficient environment caused by release of a large quantity of Butane, especially in a confined space, a person may experience symptoms such as headache, ringing in the ears, dizziness, drowsiness, unconsciousness, nausea, vomiting and depression of all the senses.
Being confined to an oxygen-deficient environment for a prolonged period of time can even prove fatal.
Description: Propane is a by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, barbecues, portable stoves and residential central heating.
A mixture of propane and butane, used mainly as vehicle fuel, is commonly known as liquefied petroleum gas (LPG or LP gas). It may also contain small amounts of propylene and/or butylene.
An odorant such as ethanethiol or thiophene is added so that people can easily smell the gas in case of a leak.
