Abstract: Natural gas has become one of the most preferred sources of energy for people around the world. It is more and more abundant, one of the cleanest fossil energies available, and with proper protocols, can be made relatively safe for use. The importance of focusing on safety was brought to the forefront by the 1937 New London, Texas tragedy in which hundreds of lives were lost in an explosion at a school caused by an undetected gas leak. At the time, natural gas was not odorized, and natural gas leaks were undetectable by the general public. Lawmakers around the world quickly realized that their constituents, and their own families, were exposed to a growing danger. As the use of clean natural gas expanded, something had to be done to alert people before the concentration of natural gas in air became explosive. Chemists found a simple way to solve this issue. When gas was made from coal, it had a distinctive sulfuric odor, but pure natural gas is odorless. By adding back that distinctive odor to the gas, people could easily detect the odor and the possibility of a gas leak. The odorization of natural gas created a system that warns people before the concentration of gas in the air becomes dangerous.
