CAS Number: 2439-35-2
EC Number: 219-451-9
Impurities and Stabilizing Additives: Not classified as hazardous at typical levels.
Inhalation: Remove patient to fresh air. Seek immediate medical attention if symptoms develop. If breathing has stopped, administer artificial respiration.
Skin Contact: Remove contaminated clothing. Immediately wash affected skin with copious amounts of soap and water for at least 15 minutes. Seek prompt medical attention for burns or persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do, continue rinsing thoroughly. Seek specialized medical care immediately.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by a medical professional. Seek immediate medical advice. Never give anything by mouth to an unconscious person.
Most Important Symptoms: Severe eye and skin irritation, possible chemical burns, delayed allergic reactions, nausea, dizziness if inhaled.
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray. Avoid full water jet to prevent spread.
Special Hazards: Vapors may form explosive mixtures with air. Closed containers may rupture if heated. Combustion may produce acrid smoke, toxic nitrogen oxides, carbon monoxide, carbon dioxide.
Personal Protection: Firefighters should wear self-contained breathing apparatus and full protective clothing. Avoid inhaling combustion products.
Advice for Firefighters: Move containers from fire area if safe. Cool exposed tanks with water spray to prevent pressure buildup. Collect contaminated fire water separately to prevent entry to drains, soil, or waterways.
Explosion Risk: Containers exposed to fire or heat may explode due to vapor expansion, especially if sealed.
Personal Precautions: Evacuate area. Ventilate enclosed spaces. Remove all sources of ignition. Wear chemical-resistant gloves, eye/face protection, and antistatic footwear.
Environmental Precautions: Prevent further leakage or spillage if safe to do. Do not let product enter drains, watercourses, or soil. Alert authorities if significant spill has entered environment.
Containment and Cleanup: Stop leak if you can do so safely. Soak up with inert absorbent (sand, silica, earth, vermiculite). Shovel residue into chemical waste container, keep away from incompatible materials. Wash spill site after material pick-up is complete.
Special Instructions: Ensure adequate ventilation. Use only spark-proof tools.
Safe Handling: Avoid contact with skin, eyes, and clothing. Use only in well-ventilated areas. No smoking, open flames, or sources of static in handling areas. Ground and bond containers when transferring.
Storage: Store in tightly closed, properly ventilated containers away from heat, sparks, and open flame. Store below 25°C. Protect from direct sunlight, moisture, and strong oxidizing agents. Store with adequate inhibitor present.
Special Storage Requirements: Containers must be labeled correctly, equipped with pressure relief. Inspect for leaks regularly. Keep away from food, drink, and animal feed.
Recommended Materials: Stainless steel, glass, or compatible HDPE containers recommended for bulk storage and transport.
Engineering Controls: Work in fume hood or ensure good general/exhaust ventilation. Prevent vapor build-up using local extraction. Clearly mark all storage areas.
Exposure Limits: No established OSHA/ACGIH exposure limits. Handle with care to minimize exposure.
Personal Protective Equipment: Wear impervious gloves (nitrile, butyl rubber), tightly fitting chemical safety goggles, and lab coat or flame retardant coveralls. In case of insufficient ventilation, use approved organic vapor respirator or supplied air.
Environmental Precautions: Install spill containment, have eye wash and safety showers available at work stations. Prohibit eating, drinking, and smoking in work areas.
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling. Remove and wash contaminated clothing before reuse.
