Hazards Identification Potential Acute Health Effects Potential Chronic Health Effects Hazardous in case of skin contact (irritant), of eye contact (irritant). Slightly hazardous in case of ingestion, of inhalation. Slightly hazardous in case of skin contact (sensitizer). CARCINOGENIC EFFECTS: MUTAGENIC EFFECTS: TERATOGENIC EFFECTS: DEVELOPMENTAL TOXICITY: Section 4. First Aid Measures Eye Contact Skin Contact Serious Skin Contact Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention. In case of contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove contaminated clothing and shoes. Cold water may be used.wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention. Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention. Inhalation Serious Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Ingestion Serious Ingestion Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband. Section 5. Fire and Explosion Data Flammability of the Product Auto-Ignition Temperature Flash Points Flammable Limits Products of Combustion Non-flammable. Fire Hazards in Presence of Various Substances Explosion Hazards in Presence of Various Substances Fire Fighting Media and Instructions Fire Hazards Explosion Hazards Risks of explosion of the product in presence of mechanical impact: Risks of explosion of the product in presence of static discharge: When heated to decomposition it emits toxic fumes of sulfur oxides, hydrogen sulfide, and sodium oxide An explosion may occur if triturated with nitrates, chlorates, or permanganates.

3 Sodium thiosulfate pentahydrate Page Number: 3 Section 6. Accidental Release Measures Small Spill Large Spill Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Section 7. Handling and Storage Precautions Storage Do not breathe dust. Wear suitable protective clothing. If you feel unwell, seek medical attention and show the label when possible. Avoid contact with skin and eyes. Keep away from incompatibles such as oxidizing agents, acids. Hygroscopic. Keep container tightly closed. Keep container in a cool, well-ventilated area. Section 8. Exposure Controls/Personal Protection Engineering Controls Personal Protection Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Personal Protection in Case of a Large Spill Exposure Limits Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

4 Sodium thiosulfate pentahydrate Page Number: 4 Section 1. Stability and Data Stability Instability Temperature Conditions of Instability Incompatibility with various substances Corrosivity The product is stable. Incompatible materials, moisture Reactive with oxidizing agents, acids. Non-corrosive in presence of glass. Corrosivity Polymerization It is a strong reducing agent and can react with oxidizers. Reacts with acids to release sulfur dioxide. Sodium Thiosulfate pentahydrate dissolves in its own water of hydation; it effloresces in warm dry air. Sodium Thiosulfate pentahydrate loses water at 1 deg. C. It is incompatible with iodine, acids, lead, mercury, and silver salts (e.g. silver nitrate), halogens. Hygroscopic; keep container tightly closed. Protect from moisture Will not occur. Section 11. Toxicological Information Routes of Entry Toxicity to Animals Chronic Effects on Humans Other Toxic Effects on Humans Toxicity to Animals Chronic Effects on Humans other Toxic Effects on Humans Inhalation. Ingestion. LD5: LC5: Hazardous in case of skin contact (irritant). Slightly hazardous in case of ingestion, of inhalation. Acute Potenial Health Effects: Skin: Causes skin irritation. Eyes: Causes eye irritation. Inhalation: May cause upper respiratory tract and mucous membrane irritation. Ingestion: Sodium Thiosulfate is an agent with a low order of toxicity. Ingestion of large doses may cause gastrointestinal irritation disturbances with nausea, vomiting, abdominal cramping, diarrhea, metabolic acidosis, and hypernatremia. I may result in a cathartic (laxative, purging) effect. May also affect respiration (cyanosis, respiratory stimulation), cardiovascular(hypotension), behavior (ataxia, convulsions) Chronic Potential Health Effects: Skin: Prolonged or repeated skin contact may allergic dermatitis, and irritation. Section 12. Ecological Information Ecotoxicity BOD5 and COD Products of Biodegradation Toxicity of the Products of Biodegradation Possibly hazardous short term degradation products are not likely. However, long term degradation products may arise. The product itself and its products of degradation are not toxic.
