General Advice: Move victim away from contaminated area. Seek immediate medical attention.
Inhalation: Remove to fresh air, keep at rest. If breathing becomes difficult, administer oxygen, call poison center or physician.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water for at least 15 minutes. Seek medical advice.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, keep eyelids open, continue rinsing. Obtain medical aid immediately.
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical attention. Never administer anything by mouth to an unconscious person.
Most Important Symptoms: Severe irritation or burns to all exposed tissues, vomiting, respiratory distress, collapse
Special Notes for Doctor: Treat symptomatically, monitor for chemical pneumonitis in inhalation cases.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, or carbon dioxide.
Unsuitable Extinguishing Media: Direct water jet may spread fire.
Hazards Arising from Chemical: Highly flammable vapors, combustion may generate toxic fumes including nitrogen oxides, ammonia, and carbon monoxide.
Protective Equipment and Precautions: Firefighters should wear self-contained breathing apparatus and full protective clothing.
Special Procedures: Cool containers with water spray to prevent explosions. Prevent run-off to waterways or sewers.
Personal Precautions: Evacuate area, ventilate; remove sources of ignition. Avoid breathing vapor, avoid skin and eye contact. Use protective equipment.
Environmental Precautions: Prevent spillage or runoff into drains or watercourses. Cylinders or containers should not be flushed into surface water.
Methods for Cleanup: Absorb with non-combustible, inert material like sand or earth, collect and dispose in suitable closed containers for disposal. Clean area with water and detergent.
Other Instructions: Notify authorities if large quantities enter water, soil or sewers. Use non-sparking tools.
Handling: Use in well-ventilated area, ground all equipment. Keep away from heat, sparks, open flames. Avoid inhalation, ingestion, skin or eye contact. Do not eat, drink, smoke during use.
Storage: Keep in tightly closed container, store cool, dry, and well-ventilated place. Separate from oxidants, acids, and foodstuffs. Keep away from incompatible substances and out of sunlight.
Packaging Materials: Use containers made of compatible materials such as steel with proper lining. Avoid plastics not rated for strong amines.
