SECTION 3. COMPOSITION / INFORMATION ON INGREDIENTS
Chemical name: Uranyl Sodium Carbonate / Sodium Uranyl Carbonate
CAS RN: 13021-32-4
Concentration: 100%
Molecular weight: 436.02 g/mol
SECTION 4. FIRST-AID MEASURES
General advice: Obtain medical attention after significant exposure. Provide this SDS to the medical provider. Move the exposed person away from the source of exposure without placing responders at risk. Consider both chemical toxicity and radiological contamination.
Inhalation: Move the exposed person to fresh air. If breathing is difficult, trained personnel may provide appropriate respiratory support. If not breathing, trained personnel should provide CPR/artificial respiration as appropriate. Obtain immediate medical attention.
Skin contact: Remove contaminated clothing. Wash exposed skin thoroughly with soap and water. Obtain medical attention if symptoms occur or after significant exposure. Manage contaminated clothing under applicable radiological-contamination procedures.
Eye contact: Immediately flush eyes with water for at least 15 minutes, holding eyelids open. Remove contact lenses if easy to do. Obtain immediate medical attention.
Ingestion: Rinse mouth with water if conscious. Do not induce vomiting unless directed by qualified medical personnel. Do not give anything by mouth to an unconscious person. Obtain immediate medical attention.
Most important symptoms/effects: Significant internal uranium exposure can produce systemic toxicity, and internal radioactive contamination presents an additional radiological hazard.
Indication of immediate medical attention/special treatment: Immediate medical evaluation is recommended following significant ingestion, inhalation, or suspected internal contamination. Specific treatment should be determined by qualified medical and radiation-safety professionals.
SECTION 5. FIRE-FIGHTING MEASURES
Suitable extinguishing media: Water spray, alcohol-resistant foam, dry chemical, or carbon dioxide may be used for the surrounding fire as appropriate to the circumstances and facility emergency procedure.
Specific hazards arising from the chemical: Potential decomposition products include carbon oxides and uranium oxides. Fire, smoke, dust, debris, and firefighting runoff may spread radioactive contamination.
Special protective equipment and precautions for firefighters: Wear positive-pressure SCBA and protective clothing appropriate to the fire. Approach from upwind where possible. Establish radiological controls and notify the Radiation Safety Officer or qualified radiological emergency-response authority.
Additional precautions: Contain contaminated firefighting runoff and prevent uncontrolled environmental release.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Evacuate/isolate the affected area as appropriate. Avoid breathing dust. Keep unnecessary personnel away. Wear appropriate protective equipment and follow the facility’s radioactive-material response procedures.
Emergency procedures: Notify the Radiation Safety Officer/radiological response authority. Assess airborne and surface contamination before cleanup.
Environmental precautions: Prevent material from entering drains, soil, surface water, or groundwater. Prevent further leakage or spillage if safe to do so.
Methods and materials for containment and cleaning up: For small spills, trained personnel may use an appropriate inert absorbent where compatible with the material and facility procedure. Carefully collect the material and contaminated absorbent into a properly controlled container for radioactive-waste management. Avoid creating airborne dust. Do not use compressed air.
SECTION 7. HANDLING AND STORAGE
Precautions for safe handling: Treat the material as hazardous and radioactive. Avoid direct physical contact and formation of dust/aerosols. Use appropriate approved safety equipment. Only trained and authorized personnel should handle the chemical or its container. Use local exhaust/process ventilation or a chemical fume hood where dust may be generated.
Radiological controls: Apply the facility’s radioactive-material handling procedures, contamination controls, surveys, dosimetry, access restrictions, and ALARA principles as applicable.
Conditions for safe storage: Protect from physical damage. Store in a cool, dry, well-ventilated, secure area. Protect personnel from radiation exposure and contamination as required by the facility program. Keep container tightly closed.
Incompatibilities: Separate from readily oxidizable or combustible materials. Avoid reducing agents, active metals, cyanides, esters, thiocyanates, and other incompatible materials identified by validated compatibility procedures.
Specific end uses: Laboratory chemicals and manufacture of substances.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure limit: OSHA PEL of 0.05 mg. Because uranium exposure limits are concentration-based and may depend on solubility class, the applicable current OSHA/NIOSH limit should be verified before controlled issuance. The chemical exposure limit and radiological dose limits are separate controls.
Radiological exposure controls: Use appropriate dosimetry, contamination surveys, airborne monitoring, time/distance/shielding controls, and written procedures under the applicable radioactive-material license and facility radiation-protection program.
Engineering controls: Use local exhaust ventilation, process enclosure, glovebox, or other containment capable of controlling airborne uranium-containing dust. Maintain appropriate contamination controls.
Eye/face protection: Use safety glasses and a face shield where particle projection or splash hazards are possible.
Skin protection: Wear appropriate protective gloves and clothing. Inspect gloves before use and replace contaminated or damaged gloves. Wash hands thoroughly after handling.
Respiratory protection: Use only under a compliant written respiratory-protection program. Respirator selection must be based on measured or anticipated airborne concentration, oxygen level, contaminant characteristics, and radiological requirements. For IDLH or firefighting conditions, use positive-pressure SCBA or an appropriate supplied-air respirator with auxiliary SCBA.
Environmental exposure controls: Prevent leakage or spillage. Do not allow the product to enter drains. Avoid uncontrolled environmental release.
