Propane versus Gasoline
Let's make something clear lest someone gets confused here.
Gasoline is easily detected in an open environment because of its odor, as Less has indicated.
Propane gas itself is also easily detected because of a chemical additive that gives it a characteristic "rotten egg" smell.
A byproduct of the combustion of both products is carbon monoxide. It is this gas that is colorless and odorless and not readily detectable.
The recall we are talking about references a possible leaky gasket that allows combustion gasses (including CO) to leak into the home, possibly causing death to occupants.
To a lesser but just as fatal extent, other popular heaters that utilize kerosene and even your trusty old oil burner can easily vent CO gas into a living space if a failure in the burner or vent/chimney system occur.
Its short money to equip your home or camp with a CO detector or combination CO/fire alarm. No living space that uses gas or oil or kerosene should be without one!
