Inhalation: Move to fresh air immediately, seek medical advice if symptoms like coughing or difficulty breathing occur
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with soap and water for at least 15 minutes, consult a physician if irritation persists
Eye Contact: Rinse cautiously with water for at least 15 minutes, lift upper and lower eyelids, remove contact lenses, seek medical attention right away
Ingestion: Rinse mouth, never give anything by mouth to an unconscious person, seek medical help fast, risk of nausea and abdominal pain
Advice to Physician: Treat symptomatically, provide supportive care, watch for respiratory distress and dehydration
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or CO2 extinguishers
Special Hazards: Gives off toxic fumes of nitrogen oxides and carbon oxides under fire, risk of flashback if chemical is vaporized
Protective Equipment: Firefighters wear self-contained breathing apparatus, chemical-resistant suits recommended, area may need evacuation
Hazardous Combustion Products: Nitrogen oxides, carbon monoxide, carbon dioxide
Advice: Cool containers exposed to fire with water spray, avoid breathing vapors, stay upwind
Personal Precautions: Wear gloves, eye protection, and mask, ventilate area thoroughly
Environmental Precautions: Prevent leaks into drains, surface water, or soil, notify authorities if large spill threatens environment
Methods for Cleanup: Absorb with inert spill absorbent (vermiculite, sand), collect in sealed containers for hazardous waste disposal, wash spill site after cleanup complete
Decontamination: Non-reactive disinfectants and copious water recommended, equipment must be cleaned before reuse
Non-Emergency Procedures: Restrict access, use wet-cleaning methods to keep dust down to a minimum, avoid mixing with incompatible substances during cleanup
Safe Handling: Use under chemical fume hood, avoid breathing dust or vapor, keep containers tightly closed, avoid spills
Personal Hygiene: Always wash hands after handling, don’t touch face, food, or beverages while working
Storage Conditions: Store in cool, dry, well-ventilated area away from sunlight and moisture
Incompatible Materials: Avoid oxidizing agents, acids, acid chlorides, acid anhydrides and strong bases
Packing Materials: Use non-reactive packaging, glass or high-density polyethylene best for long-term stability
Specific End Uses: Restricted to trained professionals, never use in food or medical applications without approval
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV, minimize exposure as much as possible
Engineering Controls: Local exhaust ventilation, chemical fume hood, closed transfer systems for large-scale use
Personal Protection: Chemical-resistant gloves (nitrile recommended), splash goggles, lab coat, closed-toe shoes
Respiratory Protection: Wear NIOSH approved respirator if vapor or dust concentrations exceed safe handling limits
Hygiene Measures: Remove and wash contaminated clothing immediately, do not take contaminated garments home
Environmental Controls: Keep away from drains, work on spill containment plans if used in large scale production
