Safety and Handling of Monochloro Benzene

1. Personal Protective Equipment (PPE):
   • Gloves: Wear chemical-resistant gloves (e.g., nitrile or rubber gloves) to prevent skin exposure.
   • Eye Protection: Always use safety goggles or a face shield to protect eyes from splashes.
   • Respiratory Protection: Use a respirator with an appropriate filter if ventilation is insufficient or if exposure to fumes or vapors is likely.
   • Clothing: Wear protective clothing such as lab coats, aprons, and long-sleeved shirts to protect against skin contact.
2. Handling:
   • Monochloro benzene is a flammable liquid and must be handled with care in well-ventilated areas to avoid inhalation of vapors.
   • Avoid contact with open flames or heat sources. Ensure the area is grounded and bonded to prevent static discharge.
   • Use appropriate fume hoods when working with this compound in laboratory settings to minimize inhalation exposure.
3. Storage:
   • Store in a cool, dry, and well-ventilated area, away from sources of heat or open flames.
   • Keep the container tightly closed and ensure it is labeled properly with its contents and hazard information.
   • Store away from strong oxidizing agents and alkalies.
4. First Aid:
   • Inhalation: Move the affected person to fresh air immediately. If symptoms persist, seek medical attention.
   • Skin Contact: Wash affected skin with soap and water immediately. Seek medical attention if irritation or burns develop.
   • Eye Contact: Flush eyes with water for at least 15 minutes. Seek immediate medical attention if irritation or injury persists.
   • Ingestion: Do not induce vomiting. Rinse the mouth with water and seek medical help immediately.
5. Hazards:
   • Inhalation: Vapors can cause respiratory irritation, dizziness, headache, and nausea.
   • Skin Contact: Can cause irritation and chemical burns on prolonged exposure.
   • Eye Contact: Can cause severe eye irritation and damage.
   • Ingestion: Can be harmful or fatal if swallowed. Causes irritation and possible damage to internal organs.
