There is no gases that comes out of a volcano that is not poisonous all gases that comes from a volcano is dangerous.
Volcanoes emit several gases, and not very nice ones (hence the reason that nothing living can exist inside the crater of a volcano). Two gases that volcanoes emit that are NOT poisonous include water and carbon dioxide. On the other hand, they also emit nasty gases like sulfur dioxide.
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
Explosive types of volcanoes are typically referred to as stratovolcanoes or composite volcanoes. These volcanoes are characterized by their steep sides and explosive eruptions caused by trapped gases and thick, viscous lava. Examples include Mt. St. Helens in the United States and Mt. Fuji in Japan.
