Sodium hypophosphite Page Number: 2 Section 3. Hazards Identification Potential Acute Health Effects Slightly hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Potential Chronic Health Effects CARCINOGENIC EFFECTS: MUTAGENIC EFFECTS: TERATOGENIC EFFECTS: DEVELOPMENTAL TOXICITY: Repeated or prolonged exposure is not known to aggravate medical condition. 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 if irritation occurs. Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops. Cold water may be used. 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. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention if symptoms appear. Section 5. Fire and Explosion Data Flammability of the Product Auto-Ignition Temperature Flash Points Flammable Limits Products of Combustion Fire Hazards in Presence of Various Substances Non-flammable. Explosion Hazards in Presence of Various Substances Risks of explosion of the product in presence of mechanical impact: Slightly explosive in presence of open flames and sparks. Fire Fighting Media and Instructions Fire Hazards Explosion Hazards Sodium Hypophosphite decomposes when heated, forming phosphine, a spontaneously flammable gas. Explosions can occur when hot Sodium Hypophosphite solution is evaporated. A mixture of Sodium Nitrate and Sodium Hypophosphite constitutes a powerful explosive. A mixture of Potassium Nitrate and Sodium Hypophosphite constitutes a powerful explosive. Mixture of Sodium Hypophosphote and chlorates or nitrates will explode if moistened, then dried slowly over flame.
Sodium hypophosphite 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 ingest. Do not breathe dust. If ingested, seek medical advice immediately and show the container or the label. Keep away from incompatibles such as oxidizing agents. 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. Safety glasses. 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.
