First Aid Measures

Inhalation: Move victim to fresh air, keep at rest, seek medical advice if symptoms continue
Skin Contact: Remove contaminated clothing, wash affected skin thoroughly with soap and water, consult a doctor if rash or irritation develops
Eye Contact: Rinse eyes with clean running water for at least 15 minutes, remove contact lenses if present, seek immediate medical attention if discomfort persists
Ingestion: Rinse mouth with water, do not induce vomiting, call a poison center or doctor immediately
Important Symptoms: Redness, irritation of eyes and skin, coughing or wheezing when inhaled, stomach discomfort if swallowed

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Direct water stream may spread burning material
Specific Hazards: Product vapors can form explosive mixtures with air, burning emits toxic fumes including carbon monoxide and carbon dioxide
Protective Equipment: Wear full protective clothing and self-contained breathing apparatus
Special Procedures: Cool exposed containers with water spray to prevent rupture, evacuate area if large fire

Accidental Release Measures

Personal Precautions: Use personal protective equipment, avoid contact with spilled material, ensure ventilation in affected area
Environmental Precautions: Prevent product from entering drains or waterways, notify authorities if large spill might reach natural bodies of water
Spill Clean-up Methods: Absorb with inert material such as sand or earth, collect waste in closed, labeled containers for disposal, wash area with water and collect runoff
Large Spill Response: Evacuate all non-essential personnel, contain spill with dikes, use non-sparking tools for cleanup

Handling and Storage

Precautions for Safe Handling: Use only in well-ventilated areas, avoid inhaling vapors, avoid direct skin and eye contact, keep containers tightly closed when not in use
Hygiene Practices: Wash hands and exposed areas thoroughly after handling, change contaminated clothing before entering eating areas
Safe Storage Conditions: Store in cool, dry, and well-ventilated location, separate from oxidizers, heat sources, and direct sunlight, use proper grounding/bonding if transferring large quantities
Packaging Materials: Keep in original packaging or compatible sealed containers made of metal or plastic

Exposure Controls and Personal Protection

Exposure Limits: No specific occupational exposure limits established, general industry standards apply
Engineering Controls: Use local exhaust or general dilution ventilation to control vapor concentration
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile, neoprene), safety goggles, and protective clothing to prevent skin exposure
Respiratory Protection: If vapor concentration exceeds recommended levels, use properly fitted air-purifying respirators
Hygiene Measures: Wash hands after handling, avoid touching eyes or mouth during use, provide eyewash stations and safety showers where exposure risk exists
