Source and Composition

Propane's distinct smell comes from a chemical called mercaptan, which is intentionally added to the gas during processing.

When propane is used in homes or businesses, it's important to understand that the gas is usually stored in a liquid form inside pressurized tanks. As the pressure is released, it becomes a gas, carrying that telltale mercaptan smell with it. This is your warning signal—an alert that something's not right.
Knowing the source and composition of that smell helps you take action if you ever detect it. If you catch a whiff of that funky odor, don't hesitate to investigate further or call for help.
