P-103: Guideline for the Prevention of Odor Fade in Carbon Steel Propane Cylinders and Tanks (Formerly TB-21)

Abstract

This publication explains the role of odorants in propane as a critical safety measure to aid in leak detection and prevent flammable gas accumulations. It describes the use of ethyl mercaptan as the primary propane odorant in the United States, outlines regulatory requirements for effective odorization, and discusses limitations in odor detection. The publication focuses on the phenomenon of odor fade, in which ethyl mercaptan can lose effectiveness due to chemical interactions, and provides relevant information for propane tank and cylinder fabricators as well as those who handle and fill liquefied petroleum gas containers.
