Safety and Handling of 2-Naphthol Solution

1. Personal Protective Equipment (PPE):
   • Gloves: Wear chemical-resistant gloves (such as nitrile or rubber gloves) to avoid direct skin contact.
   • Eye Protection: Always use safety goggles or a face shield to protect the eyes from splashes.
   • Respiratory Protection: Use a respirator if working in poorly ventilated areas or with large quantities, especially when handling solvents.
   • Clothing: Wear lab coats or other protective clothing to avoid skin exposure.
2. Handling:
   • Handle 2-naphthol solution in a well-ventilated area. Perform work in a fume hood to prevent inhaling fumes or vapors.
   • Always ensure that the containers of 2-naphthol solution are properly labeled and tightly closed when not in use.
   • Avoid generating dust or aerosols when handling this product in powder form.
3. Storage:
   • Store the solution in a cool, dry, and well-ventilated area. Keep it away from heat, moisture, and direct sunlight.
   • Ensure containers are airtight and securely sealed to minimize exposure to air and moisture.
   • Store away from oxidizing agents, alkalies, or strong acids to avoid dangerous reactions.
4. Disposal:
   • Dispose of 2-naphthol solution according to local regulations for hazardous chemicals.
   • Do not dispose of the solution in sewers or waterways.
   • Clean up spills using non-flammable absorbents, and dispose of them in designated hazardous waste containers.
5. Toxicity and Health Hazards:
   • Inhalation: Inhalation of vapors or dust may cause respiratory irritation, dizziness, and headaches.
   • Skin Contact: May cause skin irritation or sensitization upon prolonged exposure.
   • Eye Contact: Can cause eye irritation. Prolonged exposure may result in more severe eye conditions.
   • Ingestion: Ingesting the solution may cause gastrointestinal irritation, nausea, and vomiting.
6. First Aid:
   • Inhalation: If inhaled, remove the person to fresh air immediately. If symptoms persist, seek medical attention.
   • Skin Contact: In case of skin contact, wash the affected area thoroughly with soap and water. Seek medical attention if irritation persists.
