Physical Dangers: Chemical Dangers: The substance decomposes on contact with acids , bases , ammonia alcohols , and on heating producing toxic gases including hydrogen cyanide . Reacts with carbon dioxide or slowly with water to produce hydrogen cyanide . Occupational Exposure Limits: TLV not established. Decomposition in moist air results in hydrogen cyanide exposure: TLV: (for Hydrogen cyanide and some cyanide salts, as CN) 4.7 ppm as STEL; (Ceiling value); (ACGIH 2005). MAK: (as CN) (Inhalable fraction) 2 mg/m3 Peak limitation category: II (1); skin absorption (H); Pregnancy risk group: C; (DFG 2004). Routes of Exposure: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of Short-Term Exposure: The substance is severely irritating to the eyes the skin and the respiratory tract . The substance may cause effects on the cellular respiration , resulting in convulsions and unconsciousness . Exposure may result in death. Medical observation is indicated. See Notes. Effects of Long-Term or Repeated Exposure: The substance may have effects on the thyroid.
