Question

why is the leakage of LPG detected easily although it is odourless?

Answer 1

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