Inhalation:Irritating to the nose, mucous membranes and respiratory tract. Ingestion:No specific information is available on the physiological effects of ingestion. Acute Health Affects:Irritating to skin, eyes and respiratory tract. Chronic Health Affects:Exposure to ruthenium tetroxide dust and vapors may cause severe permanent damage to eyes and lungs. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel. SECTION 5: Fire Fighting Measures Flash Point:not applicable Autoignition Temperature:not applicable Explosion Limits:not applicable Extinguishing Medium:Aqueous solution - non-flammable When dry acts as an oxidizer towards organics. Smothering the fire may not be effective. A NIOSH approved Special Fire Fighting Procedures: self contained breathing apparatus should be worn. Hazardous Combustion andToxic ruthenium tetroxide could be present in gasses. Decomposion Products: Wetting the dried solid with small amounts of alcohols, solvents or combustible powders may lead to ignition Unusual Fire or Explosion Hazards: and fire. SECTION 6: Accidental Release Measures Small spills should be flushed with sodium bisulfite solution to detoxify ruthenium tetroxide, and then be mixed Spill and Leak Procedures: with vermiculite or sodium carbonate and swept up. Do not mix with combustible materials. SECTION 7: Handling and Storage Handling and Storage:Store in a cool dark place in tightly closed containers. SECTION 8: Exposure Controls and Personal Protection Eye Protection:Always wear approved safety glasses when handling a chemical substance in the laboratory. Skin Protection:Wear appropriate chemical resistant gloves and protective clothing. Ventilation:Material may form a fine dust or vapor. If possible, handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134. Ventilation:Material may form a fine dust or vapor. If possible, handle the material in an efficient fume hood. Additional Protection:No additional protection required.
