Disodium sulfite, sodium sulfite Section 03 - Hazard Identification Inhalation Inhalation of dust may irritate respiratory tract. Skin Contact / Absorption.... Dust may cause skin irritation from prolonged contact. Solutions will irritate skin. Eye Contact Dust may irritate or burn eyes. Solutions will irritate or burn eyes. Ingestion.....Ingestion may irritate gastrointestinal tract. May cause severe allergic reaction in some asthmatics and sulphite sensitive individuals. Large doses may cause violent colic and diarrhea, circulatory disturbances, central nervous system depression and even death. Exposure Limits...None established for sodium sulphite. The decomposition product of sulphur dioxide and cobalt sulphate has the following limits: OSHA/TWA: 5ppm (sulphur dioxide) ACGIH/TLV: 5ppm (sulphur dioxide) ACGIH/STEL: 2ppm (sulphur dioxide) OSHA/PEL: 0.1mg/m 3 (cobalt sulphate) ACGIH/TLV: 0.02mg/m 3 (cobalt sulphate) Section 04 - First Aid Measures Inhalation Remove victim to fresh air. Seek medical attention if irritation, suffocation or other symptoms develop. Skin Contact / Absorption... Remove contaminated clothing. Wash affected area with soap and water. Seek medical attention if irritation occurs or persists. Eye Contact Flush immediately with water for at least 20 minutes. Forcibly hold eyelids apart to ensure complete irrigation of eye tissue. Seek immediate medical attention.
