What Does a Natural Gas Leak Smell Like?
Natural gas is a gaseous hydrocarbon mixture with methane serving as the main gas. Methane is a simple asphyxiant that displaces oxygen in the air. If the methane concentration is high enough, the result is hypoxia and asphyxia (suffocation). If you suspect a natural gas leak, leave the building and contact the gas company. If people are sick, call Poison Control.
