  • Chemical Classes:Toxic Gases & Vapors -> Corrosive Gases
  • Canonical SMILES:O=S=O
  • Inhalation Risk:A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
  • Effects of Short Term Exposure:Rapid evaporation of the liquid may cause frostbite. The substance is irritating to the eyes and respiratory tract. Inhalation may cause asthma-like reactions. The substance may cause effects on the respiratory tract. This may result in asthma-like reactions, reflex spasm of the larynx and respiratory arrest. The effects may be delayed. Medical observation is indicated.
  • Effects of Long Term Exposure:Repeated or prolonged inhalation may cause asthma.
