First Aid Measures
Inhalation: Move affected person to fresh air, keep warm and at rest, seek medical attention if respiratory symptoms persist. Symptoms may include throat irritation, coughing, or dizziness.
Skin Contact: Remove contaminated clothing, rinse skin with running water for at least 15 minutes, seek medical care for any persistent pain or irritation
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses, consult medical help if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, get medical attention
Fire-Fighting Measures
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, alcohol-resistant foam
Special Hazards: During fire, toxic fumes such as hydrogen chloride, nitrogen oxides, and carbon oxides may be released
Advice for Firefighters: Wear self-contained breathing apparatus and chemical protective clothing, avoid inhaling combustion products, evacuate area if necessary, use water spray to cool containers
Accidental Release Measures
Personal Protection: Evacuate area, use proper personal protective equipment, avoid breathing vapors or particles
Environmental Precautions: Prevent discharge to drains, surface and groundwater
Methods for Containment and Clean Up: Absorb spillage with inert material like sand or vermiculite, place in labeled chemical waste containers for disposal, ventilate area, clean surface thoroughly afterwards
Handling and Storage
Handling: Avoid contact with skin, eyes, and clothing; wear protective equipment, work in well-ventilated areas; keep containers tightly closed
Storage: Store in cool, dry, well-ventilated place away from heat, ignition sources, or incompatible materials such as strong oxidizers or acids. Keep out of reach of unauthorized personnel, label containers clearly, inspect regularly
Exposure Controls and Personal Protection

Ecological Information
Ecotoxicity: Toxic to aquatic life, potential for long-term adverse effects in aquatic environments
Persistence and Degradability: Not readily biodegradable, chemical may persist in the environment
Bioaccumulative Potential: No specific data on bioaccumulation; structural characteristics raise potential for some environmental persistence
Mobility in Soil: Likely to remain mobile in aquatic environments and soils due to water solubility
Other Adverse Effects: Avoid any direct release into environment, treat spills or waste as hazardous
Disposal Considerations
Disposal Methods: Dispose of contents and container as hazardous waste via a licensed facility, according to local, regional, and national regulations
Contaminated Packaging: Triple rinse containers, puncture to prevent reuse, label and dispose as hazardous waste
Precautions: Do not flush to sewer or release to surface water or soil; work with your environmental health and safety office for proper procedures, keep documentation of waste disposal
