Ingestion: Do not induce vomiting, rinse mouth with water, never give anything by mouth to an unconscious person, get immediate medical attention
Notes for Physician: Treat symptomatically, consider possible ingestion of aromatic and nitrogen heterocycles
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, do not use water jet
Fire Hazards: Highly flammable, vapors may form explosive mixture with air, combustion releases toxic gases including nitrogen oxides, sulfur oxides
Protective Equipment for Firefighters: Full protective suit, self-contained breathing apparatus
Specific Hazards: Risk of container rupture under fire exposure, runoff from fire control may cause environmental contamination
Firefighting Instructions: Withdraw from area unless fire is small and manageable, use water spray to cool containers, prevent spread of fire by diking
Personal Precautions: Evacuate area, ventilate enclosed spaces, remove ignition sources, use protective gear including gloves, goggles, and respirator
Environmental Precautions: Prevent run-off into drains and surface waters, contain spill with inert absorbent (sand, earth), notify authorities if major spill reaches waterways
Clean-up Methods: Use non-sparking tools, absorb with inert material, place in chemical waste container, wash spill site after material pickup
Decontamination: Ventilate area, avoid direct contact with skin or eyes, dispose contaminated materials as hazardous waste
Handling: Use in chemical fume hood, avoid direct inhalation and contact, ground containers, take measures to prevent static discharge, avoid eating, drinking, or smoking
Storage: Keep in cool, dry, well-ventilated area, away from heat, open flames, sunlight, store in tightly closed chemical-resistant containers, segregate from oxidizing agents
Incompatibilities: Strong acids, bases, oxidizers
Special Requirements: Provide spill containment, label containers clearly, inspect regularly for leaks
Ventilation: Use local exhaust ventilation or chemical fume hood
Respiratory Protection: NIOSH-approved respirator for organic vapors if exposure exceeds limits
Skin Protection: Chemically resistant gloves, lab coat, chemical splash apron
Eye Protection: Chemical safety goggles, face shield for large-scale handling
Workplace Hygiene: Wash hands before breaks and after final handling, avoid contaminated clothing
Exposure Limits: No established ACGIH or OSHA limits, use good laboratory and industrial hygiene practice
