LPG (Liquefied Petroleum Gas), which primarily consists of propane and butane, is naturally odorless. Leaked gas can accumulate and pose a significant fire and explosion hazard if not detected. To ensure safety, a strong-smelling substance, usually a volatile organic sulfur compound like ethyl mercaptan (ethanethiol), is added as an odorant. This allows even small leaks to be detected by smell, prompting corrective action before a dangerous concentration of gas builds up.
