Ammonium Nitrate Extra Pure is a high-purity, white crystalline compound widely used in laboratory settings for analytical, inorganic, and physical chemistry applications. Known for its strong oxidizing properties, it serves as a reagent in redox reactions, thermal decomposition studies, and the synthesis of nitrate-based compounds. It is also used in preparing standard solutions and as a nitrogen source in experiments involving plant nutrition and environmental testing. Due to its hygroscopic and explosive nature under certain conditions, it must be handled with extreme caution in controlled environments. The extra pure grade ensures minimal contaminants, making it suitable for precise, high-sensitivity laboratory work. It should be stored in a cool, dry, and well-ventilated area away from heat, friction, and incompatible materials.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

  1. Personal Protective Equipment (PPE):
    • Wear a lab coat, safety goggles, and chemical-resistant gloves (nitrile or neoprene).
    • Use in a fume hood or a well-ventilated area—avoid inhalation of dust.
  2. Handling:
    • Handle with extreme care—ammonium nitrate is a powerful oxidizer.
    • Avoid contamination with organic materials, metal powders, acids, reducing agents, or combustible substances—it can increase fire or explosion risk.
    • Prevent dust formation and avoid physical impact or friction.
  3. Storage:
    • Store in a cool, dry, well-ventilated place in original container.
    • Keep away from heat, sunlight, and incompatible materials.
    • Use explosion-proof storage where possible; label as oxidizer.
  4. Hygiene Measures:
    • Wash hands thoroughly after handling.
    • Do not eat, drink, or smoke in work areas.
    • Clean work surfaces thoroughly after use.

FIRST AID MEASURES 

  1. Inhalation:
    • Move the person to fresh air immediately.
    • If breathing is difficult, administer oxygen.
    • Seek medical attention if symptoms like coughing or respiratory discomfort occur.
  2. Skin Contact:
    • Rinse thoroughly with plenty of soap and water.
    • Remove contaminated clothing.
    • Seek medical attention if irritation develops.
  3. Eye Contact:
    • Rinse cautiously with water for at least 15 minutes.
    • Hold eyelids open and remove contact lenses if present.
    • Seek immediate medical attention.
  4. Ingestion:
    • Rinse mouth with water.
    • Do not induce vomiting.
    • If the person is conscious, give water to dilute.
    • Seek immediate medical attention—nitrate salts can cause methemoglobinemia (oxygen transport disruption).

FIRE FIGHTING MEASURES

  1. Suitable Extinguishing Media:
    • Use water spray in large quantities.
    • Do not use dry chemicals or foam—they may be ineffective or reactive in this case.
  2. Specific Hazards:
    • Not flammable by itself, but supports and intensifies fire due to its strong oxidizing nature.
    • On heating or decomposition, releases:
      • Toxic nitrogen oxides (NO, NO₂)
      • Ammonia
  3. Protective Equipment for Firefighters:
    • Wear self-contained breathing apparatus (SCBA) and full protective gear.
    • Use remote fire-fighting techniques due to explosion risk in confined or heated conditions.

    • Evacuate area if safe to do so.
    • Cool exposed containers with water spray.
    • Prevent runoff—may contaminate water and soil, harmful to aquatic life.
