Molecular Weight: 129.25 g/mol
Inhalation: Move person to fresh air. If not breathing, provide artificial respiration. Seek medical attention.
Skin Contact: Remove contaminated clothing. Rinse skin with plenty of water for at least 15 minutes. Get medical advice.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses. Continue rinsing. Seek immediate medical help.
Ingestion: Rinse mouth. Do not induce vomiting. Drink plenty of water if conscious. Call poison center or doctor.
Most Important Symptoms: Burns, pain, redness, severe irritation; possible respiratory distress.
Note to Physician: Provide supportive measures as needed; treat chemical burns as thermal burns; monitor airway.
Suitable Extinguishing Media: Dry chemical, alcohol foam, carbon dioxide. Water can be used to cool containers.
Unsuitable Media: Do not use direct water jet on burning liquid due to the risk of spreading fire.
Specific Hazards: Emits toxic fumes of nitrogen oxides under fire conditions. Vapors are heavier than air and may travel to ignition points.
Protective Equipment: Full-body chemical protective suit, self-contained breathing apparatus recommended for firefighters.
Firefighting Instructions: Isolate hazard area; keep containers cool; control runoff to prevent environmental contamination.
Personal Precautions: Evacuate area. Ensure adequate ventilation. Remove ignition sources. Wear proper protective gear.
Environmental Precautions: Prevent entry into sewers, watercourses, or soil. Notify authorities if spill spreads.
Containment Methods: Stop leak if possible without risk. Dike affected area using inert materials like sand.
Clean Up Procedures: Absorb with non-combustible absorbents such as earth or sand. Collect in containers for proper disposal. Decontaminate spill site after material removal.
Handling: Use only in well-ventilated areas. Avoid inhalation and skin contact. Prevent static discharge.
Storage: Store in tightly closed, corrosion-resistant containers in a cool, dry, well-ventilated location away from oxidizers, acids, and foodstuffs.
Other Recommendations: Ground and bond containers during transfer; use proper containers to avoid leaks; keep out of reach of unauthorized persons.
Incompatible Materials: Oxidizing agents, acids; strong bases may cause violent reactions.
Occupational Exposure Limits: No established TLV or PEL; manufacturers often suggest occupational exposure control at the lowest feasible level.
Engineering Controls: Use local exhaust ventilation or process enclosure to keep airborne concentrations below recommended exposure limits.
Respiratory Protection: Use NIOSH-approved respiratory protection if ventilation is inadequate.
Eye/Face Protection: Chemical safety goggles and full face shield.
Skin Protection: Impervious gloves (e.g., nitrile or neoprene), long-sleeved clothing, lab coat, or apron.
Hygiene Measures: Wash hands thoroughly after handling; avoid eating, drinking, or smoking in work area.
