Question

Which gas is added to LPG to make it smell during the leakage?

Answer 1

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually of an entirely different agent, called Ethyl Mercaptan. This substance is added to the gas when it leaves the main storage terminals.

As we all know, LPG is very dangerous, because if it leaks, it can cause terrible fires and devastating explosions. To avoid this, Ethyl Mercaptan is added to the gas, which possesses that strong odor of rotten cabbages. This smell helps us detect whenever there is a leak, which actually makes a lot of sense from a safety and security perspective.
