Odorization is a process we are mandated to know about, and deal with on a daily basis. So why is it that no one likes to work with odorant? Could it be the distinctive smell that gets on our clothing, causing problems with family, friends, neighbors, and the public in general? Why do we odorize? We odorize primarily because it is a legal requirement. We also odorize for the public safety. We must inject odorant into natural gas in order to alert or warn of possible dangers (i.e. leaks). It was first proposed in Germany in the 1880’s by Von Quaglios’ use of ethyl mercaptan as a means of lead detecting the escape of blue water gas. However, most people have heard about the New London tragedy. In 1937, there was an explosion that leveled an elementary school in New London, Texas, killing 293 people of which the majority were children. For this reason, it is important that we understand the tremendous responsibility of knowing and implementing the odorization process
