You must determine if you can smell the odorant in these fuel gases. • Learn to recognize the odor of propane (LP) gas and natural gas. Local propane (LP) gas dealers will be more than happy to give you a scratch and sniff pamphlet. Use it to become familiar with the fuel gas odor. • Smoking can decrease your ability to smell.
