First Aid Measures

Inhalation: Move to fresh air, support breathing, get medical attention if discomfort persists.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical advice for persistent irritation.
Eye Contact: Rinse cautiously with water for 15 minutes, remove contact lenses if present, obtain medical attention for persistent redness or pain.
Ingestion: Rinse mouth, do not induce vomiting, drink one or two glasses of water, contact a poison control center right away.
Notes for Physician: Treat symptomatically, monitor for delayed effects and secondary infection from skin exposure.
Most Significant Symptoms: Local irritation, possible allergic reaction in sensitive subjects, headache or dizziness after inhalation of aerosol.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide.
Unsuitable Media: Do not use direct water jet as spread could occur.
Fire Hazards: Product itself is not combustible but may decompose at high temperatures to release toxic vapors (nitrogen oxides, carbon monoxide, carbon dioxide, amines).
Protection for Firefighters: Wear full protective gear with self-contained breathing apparatus.
Thermal Decomposition Products: Ammonia, nitrogen oxides, hydrocarbons, carbon monoxide.
Explosion Risk: None under normal conditions.
Special Procedures: Cool containers exposed to flames with water spray to prevent bursting.

Accidental Release Measures

Personal Precautions: Ensure adequate ventilation. Wear protective gloves, goggles, and protective clothing.
Environmental Precautions: Prevent spilled material from entering surface water, drains or soil. Inform authorities if significant environmental exposure occurs.
Containment Methods: Absorb with inert material (sand, earth, vermiculite). Stop leak if safe to do.
Cleanup Procedures: Shovel absorbed material into appropriate waste containers. Clean spill area thoroughly with water.
Decontamination: Wash area with soap and copious water to remove traces.
Disposal Requirements: Dispose of in compliance with local regulations. Avoid discharge to the environment.
Protective Measures: Use respiratory protection during clean-up in confined areas.

Handling and Storage

Handling: Avoid contact with eyes, skin, and clothing. Use only in well-ventilated areas. Do not eat, drink, or smoke during handling.
Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials.
Special Precautions: Avoid excessive heat or freezing. Keep away from strong acids and oxidizing agents.
Incompatibles: Strong acids, strong oxidizers, halogenated organic compounds.
Hygiene Measures: Wash hands and face before breaks, after handling, and before eating.
Packaging Materials: Use containers made of compatible materials (HDPE, stainless steel). Check for corrosion regularly.
Storage Life: Typical shelf life of 12–18 months under recommended conditions.

Exposure Controls and Personal Protection

Engineering Controls: Provide local exhaust in areas where vapors or mist may be generated. Ensure eye wash stations and emergency showers are accessible.
Personal Protective Equipment: Gloves (nitrile or latex), safety goggles or face shield, long-sleeved lab coat or coveralls.
Respiratory Protection: Use NIOSH-approved respirator for aerosols above exposure limits.
Occupational Exposure Limits: No established ACGIH or OSHA exposure limits, but minimize exposure as a best practice.
Environmental Controls: Avoid aerosol or mist formation. Prevent runoff to surface water.
Monitoring Requirements: Regular inspections for leaks, adequate ventilation checks.
Other Protection: Use rubber boots or apron when dealing with large volumes or splashes.
