Gadolinium SDS Page 1 of 6 Trace Sciences International ``` ## ページ 2 ```text If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water for at least 15 minutes. Use chemical shower if available. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. Remove contacts if possible. If swallowed Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician. Section 5: Fire-Fighting Measures 5.1 Conditions of flammability May burn in presence of air or emit a flammable gas in the presence of water or water vapour. Keep away from heat/sparks/open flame/hot surface/air/water. No smoking. 5.2 Suitable extinguishing media Dry powder, carbon dioxide (CO2), DO NOT USE WATER 5.3 Hazardous combustion products Hazardous decomposition products formed under fire conditions: gadolinium oxides 5.4 Special protective equipment for firefighters Wear self-contained breathing apparatus for firefighting if necessary. 5.5 Further information No data available Section 6: Accidental Release Measures 6.1 Personal precautions Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. 6.2 Environmental precautions Prevent further leakage or spillage if safe to do so. Do not let product enter drains. 6.3 Methods and materials for containment and cleaning up Sweep up and shovel. Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations. Keep in suitable, closed containers for disposal. Section 7: Handling and Storage 7.1 Precautions for safe handling Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Gadolinium SDS Page 2 of 6 Trace Sciences International ``` ## ページ 3 ```text 7.2 Conditions for safe storage Air and moisture sensitive. Never allow product to get in contact with water during storage. Keep container tightly closed in a dry and well-ventilated place. Section 8: Exposure Controls/Personal Protection 8.1 Components with workplace control parameters No data available 8.2 Personal protective equipment Respiratory protection Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Hand protection Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. Eye protection Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin and body protection Flame retardant protective clothing, the type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Hygiene measures Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Specific engineering controls Use mechanical exhaust or laboratory fume hood to avoid exposure.
