Why is natural gas scented?
Gas companies add a harmless chemical called mercaptan to give it its distinctive “rotten egg” smell. All natural gas and propane pipeline gas in Connecticut is odorized. If you smell gas near an appliance, it may be just a pilot light that has gone out or a burner valve that is open slightly.
When did they start adding smell to natural gas?
The impetus to add an odor (odorized natural gas) to gases was formed in 1937, when non-odorized natural gas ignited in a Texas school, killing over 200 children.
