Flush with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Cold water may be used. Get medical attention. Seek medical attention in case of eye contact with a radioactive material. Skin ContactIn 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. Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention in case of skin contact with a radioactive material. InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical attention in case of inhalation of a radioactive material. IngestionDo 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. Serious IngestionNot available. Section 5. Fire and Explosion Data Flammability of the Product Non-flammable.

It Fire Hazardsincreases the flammability of any combustible substance. Special Remarks on Explosion In contact with easily oxidizable substances, it may react rapidly enough to cause violent combustion or explosion. Hazards Thorium nitrate Section 6. Accidental Release Measures Small SpillUse appropriate tools to put the spilled solid in a convenient waste disposal container. Large Spill Radioactive material. Oxidizing material. Stop leak if without risk. Do not attempt recovery actions unless for rescue purposes. Do not touch damaged container or spilled material. Do not clean-up or dispose except under supervision of a specialist. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance damp using water spray. Do not touch disposal. Section 7. Handling and Storage PrecautionsKeep away from heat. Keep away from sources of ignition. Keep away from combustible material.. Do not ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such as combustible materials, organic materials. StorageKeep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies, reducing agents and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers. Section 8. Exposure Controls/Personal Protection Engineering ControlsUse 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. Personal ProtectionSplash goggles. Lab coat. Dust respirator.

Toxicity to AnimalsFor Thorium Nitrate Anhydrous, (CAS number 13823-29-5): Acute oral toxicity (LD50): 1760 mg/kg [Mouse]. Chronic Effects on Humans May cause damage to the following organs: kidneys, lungs, bone marrow. Other Toxic Effects onHazardous in case of skin contact (irritant), of ingestion, of inhalation. Humans Special Remarks onNot available. Toxicity to Animals Special Remarks onMay cause adverse reproductive effects. Thorium reproductive effects, if they occur, are likely to be mediated by Chronic Effects on Humansionizing radiation. Thorium is a suspected carcinogen. Thorium Nitrate emits radiation which could cause cancer, but no evidence of cancer has yet been found. May affect genetic material (mutagenic) Special Remarks on otherAcute Potential Health Effects: Toxic Effects on HumansSkin: Causes skin irritation with a rash, or burning feeling on contact. Eyes: Causes eye irritation. Inhalation: It can irritate the respiratory tract (nose, throat). Ingestion: May be harmful if swallowed. It may cause nausea, vomiting, dizziness, abdominal cramps, ulceration or bleeding from the small intestine, bloody diarrhea, weakness, convulsions, general depression, headache, mental impairment. Chronic Potential Health Effects: Skin: May cause dermatitis. Ingestion and Inhalation: Repeated or prolonged exposure may affect the liver, kidneys, lungs, bone marrow. It may reduce the ability of the bone marrow to make blood cells. Prolonged or repeated inhalation may cause scarring of the lungs. Note: Thorium can accumulate in the bones, lungs and lymph system. Thorium that is absorbed into the body can remain for long periods of time and increase the risk of radiation induced cancer in tissues where it is retained. Thorium nitrate Section 12.
