Inhalation: Move person to fresh air. If breathing becomes difficult, provide oxygen support or certified medical attention.
Skin Contact: Remove contaminated clothing. Wash area with soap and plenty of water for at least 15 minutes.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting unless directed by medical personnel. Seek medical attention if symptoms develop.
Symptoms of Exposure: Stinging, burning sensation, headaches, dizziness, redness and swelling of skin or eyes
Advice to Physicians: Treat symptomatically. Maintain airway and vital signs. Monitor for chemical pneumonitis in case of inhalation or ingestion.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (do not use water jet)
Unsuitable Media: Direct water jets—risk of spreading flammable material
Specific Hazards: Flammable liquid and vapor; combustion pays off toxic fumes including nitrogen oxides, silicon oxides, carbon oxides
Protective Equipment: Full protective suit, self-contained breathing apparatus demanded. Avoid breathing smoke or fumes.
Special Procedures: Use water spray to cool unopened containers near fire. Evacuate personnel to safe area.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid contact with skin and eyes, shut sources of ignition
Environmental Precautions: Prevent further leakage or spillage if safe. Avoid release to environment, block sewers and waterways, alert authorities as needed.
Containment: Absorb spill with inert absorbent material (sand, earth, vermiculite), transfer to suitable closed container for disposal.
Cleaning Methods: Clean remains with water and detergent, avoid solvent use.
Disposal of Collected Material: Dispose following local, state, and federal requirements.
Handling: Use in well-ventilated area. Avoid inhalation of vapor or mist, avoid contact with skin and eyes. Use grounding/bonding when pouring.
Storage Conditions: Store in original container tightly closed, stored in a cool, dry, well-ventilated space away from incompatible substances such as strong acids, bases, or oxidizers.
Incompatible Materials: Moisture, acids, alkalis, strong oxidizing agents
Storage Temperature: Recommended: 4–25°C. Do not freeze.
Special Considerations: Segregate from food, beverages, and feed.
Exposure Limits: No specific occupational exposure limits established for this compound; aniline and ethanol have published limits (monitor if process residuals present).
Engineering Controls: Use only in chemical fume hood or with local exhaust ventilation. Maintain eye wash and safety shower in area.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), goggles or face shield, lab coat or coveralls. For significant exposures, use respirator with organic vapor cartridge.
Respiratory Protection: If ventilation is insufficient, wear approved respirator.
Environmental Exposure Controls: Avoid exceeding local emission limits, use containment to prevent environmental release.
