For years the gas companies have been using 'Ethyl Mercaptan' (the rotten egg smell) as an odorant in propane. Ideally, when the propane leaks you would smell it and as it is heavier than propane it concentrates as the level of propane drops, thus becoming more noticeable in cylinders that are nearly empty. It is known that rust and concrete can absorb the EC odorant and so leaks of propane in old cylinders and foundations may go undetected.
