1 SODIUM SELENITE Section 1 - Chemical Product and Company Identification Product name: SODIUM SELENITE 98% MSDS Name: Sodium Selenite Synonyms: Sodiumselenite Chemical molecular formula: Na 2 SeO 3 Chemical molecular weight: Company Identification: Supplier: TAIAN HAVAY CHEMICALS CO., LTD Address: Tai an Dawenkou Gypsum Industry Park, Shandong, China Tel number: Fax number: Website: cc@goldenhighway.com Section 2 - Composition and Information on Ingredients CAS No. Chemical Name Content % Einecs/Elincs Sodium Selenite Section 3 - Hazards Identification Emergency overview: Danger! May be fatal if swallowed. May cause allergic skin reaction. May be harmful if absorbed through the skin. Poison! May cause reproductive and fetal effects. Toxic if inhaled. Contact with acids liberates toxic gas. May cause eye, skin and respiratory tract irritation. Target Organs: Kidneys, liver, skin. Potential Health Effects Eye: May cause eye irritation. Skin: May cause skin irritation. May be absorbed through the skin in harmful amounts. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath. May cause allergic sensitization in certain individuals. Ingestion: May be fatal if swallowed. May cause irritation of the digestive tract. Poison by ingestion. May cause liver and kidney damage. May cause vascular collapse and damage.

2 May cause headache. May cause cardiac abnormalities. Inhalation: May cause respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. Inhalation of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count. Toxic if inhaled. Chronic: May cause reproductive and fetal effects. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath, Laboratory experiments have resulted in mutagenic effects. Section 4 - First Aid Measures Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. Notes to Physician: Treat symptomatically and supportively. Section 5 - Fire Fighting Measures General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing Media: Water, Dry chemical, CO 2, Chemical Foam, Alcohol-resistant foam Flash Point:. Autoignition Temperature:. Explosion Limits, Lower/Upper:. Section 6 - Accidental Release Measures

3 General Information: Spills/Leaks: Section 7 - Handling and Storage Handling: Storage: Use proper personal protective equipment as indicated in Section 8. Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Provide ventilation. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin and clothing. Avoid ingestion and inhalation. Store in a cool, dry place. Keep container closed when not in use. Section 8 - Exposure Controls, Personal Protection Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Exposure Limits: None listed. Personal Protective Equipment Eyes: Wear appropriate protective eye glasses or chemical safety goggles as described by OSHA s eye and face protection regulations in 29 CFR or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. Respirators: Follow the OSHA respirator regulations found in 29 CFR or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
