Inhalation: Remove person to fresh air; provide oxygen if breathing is difficult; seek medical attention quickly
Skin Contact: Remove contaminated clothing and rinse skin with plenty of water for at least 15 minutes; seek medical help for irritation, burns, or persistent symptoms
Eye Contact: Rinse eyes immediately with flowing water for at least 20 minutes; hold eyelids apart; call emergency services without delay
Ingestion: Rinse mouth, never induce vomiting; do not offer anything by mouth if unconscious; seek urgent medical assessment
Most Important Symptoms: Burning of mucous membranes, redness, swelling, tissue damage, respiratory discomfort
Immediate Medical Attention: Needed for any exposure through eyes, skin burns, breathing difficulty, or accidental ingestion
Suitable Extinguishing Media: Small fires: dry chemical, CO2, or alcohol-resistant foam; large fires: water spray, fog
Specific Hazards: Material gives off toxic and corrosive gases, including nitrogen oxides, carbon monoxide, carbon dioxide
Special Protective Equipment: Full protective gear with self-contained breathing apparatus; avoid inhalation of combustion products
Recommendations: Move containers from fire area if safe to do so, cool with water spray, stay upwind
Personal Precautions: Wear chemical-resistant gloves, splash goggles, face shield, apron; restrict unprotected access
Environmental Precautions: Prevent further leakage; avoid discharge to drains, watercourses, or soil
Spill Cleanup Methods: Absorb small spills with inert materials (sand, earth); collect in closed, labeled containers for disposal; for large releases, dike for later disposal, ventilate area, and wash spill site after material pickup
Emergency Procedures: Evacuate area, ensure adequate ventilation, dispose contaminated materials according to local regulations
Handling: Operate in well-ventilated zones, avoid breathing vapors, do not get on skin, in eyes, or on clothing, use spark-proof tools and explosion-proof electrical equipment
Storage Conditions: Keep container tightly closed in a cool, dry, well-ventilated area; store away from acids, oxidizers, heat sources, and incompatible chemicals
Storage Materials: Only use containers made of compatible material such as HDPE, glass, or stainless steel; avoid copper or aluminum
Special Considerations: Post hazard labels on all storage sites, maintain spill response supplies nearby while handling bulk quantities
Exposure Limits: No established OSHA, ACGIH, or NIOSH exposure limits; handle as hazardous material
Engineering Controls: Use local exhaust ventilation, provide safety showers and eyewash facilities, use closed systems or process enclosures when feasible
Personal Protective Equipment: Splash-resistant goggles, chemical resistant gloves (nitrile, butyl rubber), full-length lab coats; for large volumes or splashing risk, face shield and apron
Respiratory Protection: If ventilation insufficient, wear NIOSH-approved respirator with organic vapor/acid gas cartridges
Hygiene Measures: Wash hands thoroughly after use, do not eat, drink, or smoke while using or storing
