Inhalation: Move affected person to fresh air immediately. Seek medical attention. Provide artificial respiration if not breathing. Administer oxygen if breathing is difficult.
Skin Contact: Remove contaminated clothing, wash skin with soap and plenty of water for at least 15 minutes. Seek urgent medical help.
Eye Contact: Rinse eyes thoroughly with water for no less than 15 minutes, including under eyelids. Remove contact lenses. Get medical evaluation as quickly as possible.
Ingestion: Do NOT induce vomiting. Rinse mouth with water if the patient is conscious. Get medical attention. Never give anything by mouth to an unconscious person.
Advice for Physicians: Treat symptomatically. Monitor for signs of central nervous system depression, respiratory distress, and organ toxicity.
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam. Water spray can be used for cooling containers but can spread the liquid.
Special Hazards from Combustion: Hazardous gases may form including hydrogen bromide, hydrogen chloride, and phosgene.
Protective Equipment for Firefighters: Full protective gear with self-contained breathing apparatus is essential in case of fire.
Firefighting Procedures: Isolate hazard area, evacuate non-emergency personnel, dike runoff to prevent entry into water systems.
Personal Precautions: Use personal protection including chemical-resistant gloves, goggles, and a respirator.
Environmental Precautions: Prevent product from reaching drains, waterways, or soil. Notify local environmental authorities.
Cleanup Methods: Ventilate area. Absorb spill with inert material such as sand or vermiculite, place in a chemical waste container. Decontaminate area with dilute sodium thiosulfate solution.
Handling: Use only in chemical fume hood or well-ventilated area. Prevent direct skin or eye contact. Avoid inhaling vapors. Do not eat, drink, or smoke during use.
Storage: Keep containers tightly closed in a cool, dry, well-ventilated place away from direct sunlight, food, and incompatible materials such as strong oxidizers and acids. Use corrosion-resistant packaging.
Exposure Limits: OSHA PEL: 1 ppb (0.001 ppm); NIOSH REL: 1 ppb (0.001 ppm) as time-weighted average
Engineering Controls: Use local exhaust ventilation, chemical hoods, and process enclosures as needed
Personal Protection: Wear chemical-resistant gloves, protective clothing, chemical splash goggles, and respiratory protection rated for organic vapors
Hygiene Measures: Wash hands, face, and exposed skin thoroughly after handling. Separate contaminated clothing. Clean protective gear before reuse.
