Abstract: Unfortunately many regulations are drafted on the heels of a disaster. Current regulation Odorization of Gas 49 CFR part 192.625 began setting roots after the deadly school explosion that claimed the lives of nearly 300 school children and teachers in New London Texas. The apparent cause of the explosion was an undetectable natural gas leak, that when concentrated above the lower explosive limit, found an ignition source. This explosion on March 18, 1937 may have been avoided if just 1 out of the 500+ occupants had the ability to recognize or detect the level of danger that existed. Today, regulations, guidelines, policies and procedures are active in the effort to prevent incidents as described above. The information provided in this article is meant to provide a snapshot of odorants, odorization equipment, odorization rates, tools and techniques, as well as general best practices when working with odorant presently in the natural gas industry.
