SAFETY HANDLING PRECAUTIONS

 SAFETY PRECAUTIONS

  1. Personal Protective Equipment (PPE):
    • Wear a lab coat, safety goggles, and chemical-resistant gloves (e.g., nitrile or neoprene).
    • Use a dust mask or fume hood to avoid inhalation of fine particles or vapors.

    • Handle with care in a well-ventilated area.
    • Avoid inhalation, ingestion, and contact with eyes and skin.
    • Prevent dust formation; do not mix with strong acids or alkalis.
  3. Storage:
    • Store in a tightly sealed container in a cool, dry, well-ventilated area.
    • Protect from moisture—ammonium chloride is hygroscopic and may cake.
    • Keep away from strong oxidizers and acids.
  4. Hygiene Measures:
    • Wash hands thoroughly after handling.
    • Do not eat, drink, or smoke while working in the lab.
    • Clean up spills promptly and avoid dust dispersal.

FIRST AID MEASURES 

  1. Inhalation:
    • Move person to fresh air.
    • Provide oxygen if breathing is difficult.
    • Seek medical attention if coughing or respiratory irritation occurs.
  2. Skin Contact:
    • Wash affected area with plenty of water and soap.
    • Remove contaminated clothing.
    • Seek medical attention if irritation or burns develop.
  3. Eye Contact:
    • Rinse thoroughly with clean water for at least 15 minutes.
    • Remove contact lenses if present and easy to do.
    • Seek immediate medical attention for persistent pain or irritation.
  4. Ingestion:
    • Rinse mouth with water.
    • Do not induce vomiting.
    • If the person is fully conscious, give water to dilute.
    • Seek immediate medical attention—may irritate the gastrointestinal tract.

FIRE FIGHTING MEASURES

  1. Suitable Extinguishing Media:
    • Use water spray, dry chemical, foam, or carbon dioxide (CO₂) depending on surrounding materials.
  2. Specific Hazards:
    • Non-flammable, but decomposes at high temperatures to release toxic fumes including:
      • Hydrogen chloride (HCl)
      • Ammonia (NH₃)
    • These gases can be irritating or harmful if inhaled.
