What is a required addition to LP gas and commercial natural gas by law?

The addition of odorization, specifically the use of an odorant, to liquid propane (LP) gas and commercial natural gas is mandated by law for safety reasons. This requirement is crucial because both LP gas and natural gas are inherently odorless, which poses a significant hazard if leaks occur. The introduction of a strong, distinctive odor—typically that of rotten eggs—allows for easy detection of gas leaks, enabling individuals to take immediate action to prevent potential explosions or asphyxiation.

This safety measure is vital in protecting both residential and commercial properties as well as the health and safety of the public. The regulation for odorization reflects a proactive approach to fire safety and emergency preparedness in the handling and use of these gases. Without such an odorant, the risk of unnoticed gas leaks would dramatically increase, leading to potentially catastrophic consequences.
