Inhalation: Move person to fresh air. Seek medical advice if symptoms like headache, dizziness, or drowsiness persist.
Skin Contact: Remove contaminated clothing. Wash skin with soap and water for at least 15 minutes. If irritation persists, consult a physician.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if worn and easy to do. Continue rinsing. Seek medical attention if irritation develops.
Ingestion: Rinse mouth. Do not induce vomiting. Get medical advice/attention if you feel unwell or in case of large ingestion.
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Unsuitable Extinguishing Media: High pressure water streams can spread fire.
Specific Hazards: Vapors are heavier than air and can travel long distances to ignition sources. Containers can rupture under fire conditions. Toxic gases like carbon monoxide and carbon dioxide may be released.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA) and full protective gear.
Firefighting Instructions: Cool exposed containers with water spray. Stay upwind to avoid toxic vapor exposure.
Personal Precautions: Evacuate area and eliminate ignition sources. Ventilate area. Wear suitable protective clothing, gloves, goggles.
Spill Response: Absorb spill with inert material (sand, earth). Collect and place in suitable, labeled containers. Avoid entry into sewers or waterways.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Notify environmental authorities if product enters rivers, lakes, or drains.
Decontamination: Clean area thoroughly with water and detergent after removal of substance.
Handling: Use in well-ventilated area. Avoid inhalation of vapors and contact with skin, eyes, and clothing. Ground/bond containers during transfer to avoid static discharge. Keep away from heat, sparks, open flames.
Storage Conditions: Store in tightly closed, properly labeled containers in a cool, dry, well-ventilated area away from incompatible substances such as strong oxidizers and acids. Protect from sunlight and ignition sources.
Special Precautions: Keep containers upright to prevent leaks. Check regularly for leaks or corrosion. Practice good hygiene – wash hands after handling.
Engineering Controls: Adequate ventilation such as local exhaust or fume hood. Use explosion-proof equipment where appropriate.
Occupational Exposure Limits: No established OSHA or ACGIH limits; minimize exposure.
Personal Protective Equipment (PPE):
Gloves: Nitrile, butyl rubber, or other chemical-resistant gloves.
Eye Protection: Safety glasses or goggles with side shields.
Respiratory Protection: If airborne concentrations are high, use NIOSH-approved organic vapor respirator.
