* Natural gas is mostly methane (with a bit of ethane), which is non-toxic but highly flammable. It has no odor on its own, but trace amounts of ''other'' gases{{x|methyl mercaptan and hydrogen sulfide}}are added to the supply, so people can smell if there's a dangerous gas leak. | * Natural gas is mostly methane (with a bit of ethane), which is non-toxic but highly flammable.
