Hazards Summary:

The Critical Effects for aliphatic hydrocarbon gases are CNS depression and cardiac sensitization. From a toxicologic standpoint, methane and ethane are practically inert; however, at very high concentrations, they act as a simple asphyxiant and can cause suffocation by displacement of oxygen from breathing atmosphere, below the critical level of 16% oxygen that is required to sustain life. [ACGIH] Simple asphyxiant; Causes narcosis at high concentrations; [Merck Index] Evaporating liquid can cause frostbite; [ICSC]
