First Aid Measures

Inhalation: Move person to fresh air, support breathing if symptoms develop, seek medical attention for persistent irritation or distress
Skin Contact: Remove contaminated clothing, wash area thoroughly with soap and water, monitor for irritation, seek medical attention if rash or discomfort persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get medical advice if irritation continues
Ingestion: Rinse mouth if conscious, do not induce vomiting, seek medical attention immediately

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, water spray, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water jet may not be effective
Specific Hazards: May emit toxic fumes of carbon monoxide, carbon dioxide, methylated phenols when burned
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Special Procedures: Use caution in confined spaces, cool exposed containers with water spray to prevent pressure build-up

Accidental Release Measures

Personal Precautions: Wear protective gloves, goggles, and suitable clothing, ensure adequate ventilation, avoid dust formation
Environmental Precautions: Prevent entry to drains or water systems, contain spill using inert absorbent material
Cleanup Methods: Scoop up material and place in a labeled waste container, wash area with water and mild detergent, dispose of contaminated materials as chemical waste

Handling and Storage

Handling: Operate in a well-ventilated environment, avoid inhalation or prolonged skin contact, use appropriate PPE, keep containers tightly closed after use
Storage: Store in a cool, dry place away from heat and direct sunlight, keep away from incompatible substances such as strong oxidizers and acids, lock storage area if possible, secure containers upright and clearly labeled

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established exposure limits per OSHA or ACGIH for this compound, limit exposure by engineering controls
Engineering Controls: Use fume hoods or local exhaust in laboratory settings, maintain good general ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), safety goggles or face shield, lab coat, splash-resistant footwear
Hygiene Measures: Wash hands thoroughly after handling, do not eat or drink near product use, remove contaminated clothing before entering shared areas
