Arsine (AsH3)

Arsine (AsH3)

Historically known for being used during the First World War as a chemical weapon, arsine (AsH3) – also known as arsenic trihydride – is present in many industrial processes. It is notably used in the steel industry in ferrous metal foundries (desulfurization systems cleaning), tin foundries, metal treatment, electronics sector and boiler descaling).


Arsine effects on health

Colorless at ambient temperature, arsine (AsH3) is odorless at a nascent state. Once in contact with air, it oxidizes and gets a pronounced garlic smell. As it is heavier than air, it penetrates organisms through the breathing tracts. Arsine s highly toxic when inhaled (R26) and harmful for the aquatic environment as it easily dissolves into the water. Extremely flammable (R12), it can compose explosive mixtures between 5.1 and 78% volume.
