Traditional IRA Withdrawal Rules With a Traditional, Rollover, SEP, or SIMPLE IRA, you make contributions on a pre-tax basis (if your income is under a certain level) and pay no taxes until you withdraw money. IRA withdrawal rules and penalty details vary depending on your age.
LPG (propane) smells because an odourant - Ethyl Mercaptan - is added to the gas to make it easier to detect a leak. In their natural state, LPG (Propane and Butane) and Natural Gas (Methane) are all odourless gases. The distinctive smell that people associate with these gases is actually added to them as a safety measure.
If youâve ever caught a whiff of natural gas, you know the stench is similar to that of bad eggs or rotting cabbage. But the unsavory smell also saves lives: Gas leaks put our homes at risk for fires and explosions, and can even cause asphyxiation and death. Since pure natural gas (a.k.a. methane) has no smell, utility companies add smelly, sulfur-containing odorants called mercaptans, or thiols, to warn us if anything is amiss with our pipelines.
