Safety and Handling of 2-Naphthol

1. Personal Protective Equipment (PPE):
   • Gloves: Wear chemical-resistant gloves (e.g., nitrile gloves) to prevent skin contact with 2-naphthol, which may cause skin irritation.
   • Eye Protection: Use safety goggles or a face shield to protect the eyes from splashes or contact with 2-naphthol.
   • Respiratory Protection: In areas where dust or vapors may be generated, wear a respirator or ensure the space is well-ventilated to avoid inhaling harmful fumes.
   • Clothing: Wear protective clothing (e.g., lab coats) to minimize skin exposure and contamination from 2-naphthol.
2. Handling:
   • Handle 2-naphthol in a well-ventilated area. Ensure there is no open flame or sources of heat nearby, as it is flammable.
   • Avoid generating dust or inhaling vapors during handling, particularly when in powdered form.
   • Ensure proper labeling and storage of 2-naphthol to avoid mishandling.
3. Storage:
   • Store 2-naphthol in a cool, dry, and well-ventilated area, away from heat sources, ignition points, and oxidizing agents.
   • Keep the container tightly closed when not in use, and ensure the storage area complies with local chemical safety regulations.
   • Use flammable storage cabinets if necessary, and keep it away from incompatible substances.
4. Disposal:
   • Dispose of 2-naphthol waste in accordance with local environmental regulations. Do not dispose of it in sewers, waterways, or drains.
   • Clean up spills using appropriate absorbent materials. Ensure that any contaminated surfaces are properly cleaned.
   • Ensure proper waste disposal containers are used, and that they are clearly labeled.
5. Toxicity and Health Hazards:
   • 2-Naphthol can be harmful if ingested, inhaled, or comes into skin contact.
   • Inhalation of 2-naphthol dust or vapors may cause respiratory irritation, dizziness, or headache.
   • Skin contact may lead to irritation or sensitization. Prolonged exposure may lead to more serious skin reactions.
   • Ingestion may cause nausea, vomiting, or gastrointestinal irritation.
6. First Aid:
   • Inhalation: If inhaled, remove the affected person to fresh air. Seek medical attention if symptoms persist.
   • Skin Contact: In case of skin contact, wash the affected area with soap and water immediately. Remove contaminated clothing and seek medical attention if irritation persists.
   • Eye Contact: If 2-naphthol comes into contact with the eyes, rinse immediately with plenty of water for at least 15 minutes. Seek medical advice if irritation persists.
   • Ingestion: If ingested, do not induce vomiting. Seek immediate medical attention.
