Risk Phrases: None Listed. Section 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Not available. Potential Health Effects Eye: May cause eye irritation. Skin: Low hazard for usual industrial handling. Ingestion: The toxicological properties of this substance have not been fully investigated. Inhalation: Inhalation of dust may cause respiratory tract irritation. Chronic: Several studies in rats & mice have linked sodium saccharin to bladder tumors, but the mechanism believed to induce cancer in those animals does not appear to occur in humans. Rats & mice have a different urinary pH than do humans. Section 4 - FIRST AID MEASURES Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Ingestion: Get medical aid if irritation or symptoms occur. Inhalation: Remove from exposure and move to fresh air immediately. Get medical aid if cough or other symptoms appear. Notes to Physician: Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.

Carcinogenicity: Sodium saccharin - Not listed by ACGIH, IARC, or NTP. Other: See actual entry in RTECS for complete information. Section 12 - ECOLOGICAL INFORMATION Ecotoxicity: The product is chemically identical to the natural amino acid L-Serine and can therefore can be degraded microbiologically. Section 13 - DISPOSAL CONSIDERATIONS Products which are considered hazardous for supply are classified as Special Waste and the disposal of such chemicals is covered by regulations which may vary according to location. Contact a specialist disposal company or the local waste regulator for advice. Empty containers must be decontaminated before returning for recycling.
