First Aid Measures
General advice: Get medical attention immediately. Show this safety data sheet to the doctor.
Inhalation: Move person to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration.
Skin contact: Immediately wash area with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes.
Eye contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing.
Ingestion: Do not induce vomiting. Rinse mouth with water, never give anything by mouth to an unconscious person. Seek immediate medical attention.
Symptoms: Burning sensation, coughing, headache, nausea, dizziness, vomiting, skin and eye irritation, possible respiratory issues
Fire-Fighting Measures
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water streams
Hazardous Combustion Products: Hydrogen chloride, hydrogen bromide, phosgene, carbon oxides
Protective Equipment: Wear self-contained breathing apparatus and full firefighting gear
Fire/Explosion Hazard: Vapors are heavier than air and may travel along the ground to a distant ignition source
Special Procedures: Evacuate area, do not allow water runoff to enter drains or sewers
Accidental Release Measures
Personal Precautions: Evacuate unnecessary personnel, use protective equipment to prevent contact with skin, eyes, and clothing
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid release to the environment, keep away from drains, surface and groundwater
Methods for Clean Up: Absorb liquid with inert material such as sand or earth, collect and seal in properly labeled containers for proper disposal, ventilate the area and wash spill area after collection
Emergency Procedures: Isolate hazard area and keep unauthorized personnel away
Handling and Storage
Handling: Use only in well-ventilated areas, avoid contact with skin, eyes, and clothing, do not breathe fumes/vapor, keep away from ignition sources, handle in accordance with established chemical hygiene protocols, wash hands and face after handling
Storage: Store in tightly closed containers in a cool, dry, well-ventilated, fireproof area, away from incompatible substances like strong bases, strong oxidizing agents, and water sources, keep containers tightly sealed and properly labeled
Exposure Controls and Personal Protection
Engineering Controls: Use with adequate ventilation such as chemical fume hood or local exhaust, ensure eyewash stations and safety showers are close to the work station
Eye Protection: Chemical safety goggles conforming to EN166 or equivalent
Skin Protection: Chemical resistant gloves (nitrile, PVC), long-sleeved laboratory coats, aprons
Respiratory Protection: Use NIOSH-approved respirators if ventilation is inadequate or exposure limits are exceeded
Environmental Exposure Controls: Prevent release to public water systems or sewage
Exposure Limits: No specific occupational exposure limits established; minimize exposure by use of control measures
