Physical Description	Germane is a colorless gas with a pungent odor. It is flammable. The gas is heavier than air and a flame can flash back to the source of leak very easily. It is toxic by inhalation. Prolonged exposure of the containers to fire or intense heat may result in their violent rupturing and rocketing. It is used in making electronics.Colorless gas with a pungent odor. [Note: Shipped as a compressed gas.][NIOSH]COLOURLESS COMPRESSED GAS WITH PUNGENT ODOUR.Colorless gas with a pungent odor.
