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.
Inhalation is a common route of exposure to gasoline. Generally, gasoline's odor provides adequate warning of hazardous concentrations. The odor threshold is 0.025 ppm. Its vapors are heavier than air and may cause asphyxiation in enclosed, poorly ventilated, or low-lying areas.
