Is Propane Bad to Smell

Propane gas has no odor. Propane companies add a harmless chemical called mercaptan to give it its distinctive “rotten egg” smell.

Can propane fumes harm you?

Propane vapor is not toxic, but it is an asphyxiating gas. That means propane will displace the oxygen in your lungs, making it difficult or impossible to breathe if exposed to high concentrations. If you suspect you have inhaled a significant amount of propane, call 911.

How long does propane take to dissipate?

Usually, to air propane out of your home, you will need at least two hours of proper airing.
