Most Important Symptoms: Eye or skin redness, coughing, mild headache
Suitable Extinguishing Agents: Carbon dioxide, dry chemical, foam, water spray
Specific Hazards During Fire: Fumes may contain nitrogen oxides, carbon monoxide
Protective Equipment: Full protective clothing, self-contained breathing apparatus for large fires
Special Fire Fighting Procedures: Use water spray to cool fire-exposed containers, do not use direct water jet
Personal Precautions: Ventilate area, avoid breathing fumes, wear gloves and eye protection
Environmental Precautions: Keep out of drains, surface water, soil, inform authorities of large spills
Spill Clean-Up Methods: Absorb with inert materials like sand or earth, collect residues into suitable containers, dispose according to local guidelines
Handling: Use only with adequate ventilation, wear protective gear for hands and eyes, avoid splashing
Storage: Keep original container tightly closed in cool, dry, well-ventilated place, store away from oxidizers and strong acids, label containers clearly
Incompatibilities: Keep away from strong oxidizing agents, acidic materials
Control Parameters: No established exposure limits for general industry
Engineering Controls: Local exhaust ventilation or good general air flow
Personal Protection: Nitrile or neoprene gloves, splash goggles, lab coats, closed footwear
Respiratory Protection: Not typically required for normal use, use organic vapor mask if vapors concentrated in workplace
Hygiene Practices: Wash hands before breaks and after handling, do not eat, drink, or smoke during use
