mercapitan ,, nasty stuff.. at the utility the odourant is added to the gas at the gate staitions.. i have had to move barrells of that stuff.. .you might as well burn your clothes when your'e done, cuz the smell aint comming out, if i remember correctly the concentration is somthing like i drop per million odourant to gas, occaisionally the machines would screw up, making the tiniest of gasleaks (smaller than a pinhole) very noticeable, then the next day the swit'ch board would light up with customers calling in gas leaks,
