Glacial Acetic Acid Tech grade is a clear, colorless liquid with a pungent vinegar-like odor. It is a less refined form of acetic acid primarily used for industrial and technical applications rather than food or pharmaceutical uses. Typically available in concentrations ranging from 80% to glacial (99-100%), it serves as a crucial chemical reagent, solvent, and intermediate in various industrial processes.

SAFETY HANDLING PRECAUTIONS

Safety Precautions

Personal Protective Equipment (PPE)

  • Gloves: Chemical-resistant (neoprene, nitrile, or PVC).
  • Eye/Face Protection: Goggles + face shield (mandatory for concentrated acetic acid).
  • Respiratory Protection: NIOSH-approved respirator (organic vapor cartridge) if ventilation is inadequate.
  • Body Protection: Chemical-resistant apron or suit (for large spills/high concentrations).

Handling & Storage

  • Ventilation: Use in a fume hood or well-ventilated area.
  • Static Electricity Prevention: Ground and bond containers to avoid sparks.
  • Incompatible Materials: Keep away from:
    • Oxidizers (e.g., nitric acid, hydrogen peroxide) → violent reactions.
    • Bases (e.g., sodium hydroxide) → exothermic neutralization.
    • Metals (e.g., aluminum, zinc) → corrosion & hydrogen gas release.
  • Storage:
    • Sealed, corrosion-resistant containers (HDPE, stainless steel, or glass-lined tanks).
    • Cool, dry, well-ventilated area away from sunlight and heat sources.
    • Flammable storage cabinet (if ≥80% concentration).

Hygiene Measures

  • No eating, drinking, or smoking in handling areas.
  • Emergency shower & eyewash station must be accessible.
  • Wash hands thoroughly after handling.

 First Aid Measures

Inhalation (Vapors/Fumes)

  • Move to fresh air immediately.
  • If breathing is difficult, administer oxygen and seek medical help.
  • If unconscious, perform CPR (if trained) and call emergency services.

Skin Contact

  • Remove contaminated clothing immediately.
  • Rinse with plenty of water for ≥15 minutes.
  • Apply soap to remove residual acid.
  • Seek medical attention if burns or irritation persist.

Eye Contact

  • Immediately flush eyes with water for ≥15 minutes (hold eyelids open).
  • Do NOT rub eyes.
  • Seek emergency medical care (risk of corneal damage).

Ingestion

  • Do NOT induce vomiting (risk of esophageal burns).
  • Rinse mouth with water.
  • Drink milk or water to dilute (if conscious).
  • Seek immediate medical attention.

Firefighting Measures

Fire Hazards

  • Highly flammable (≥80% concentration, flash point 39°C / 102°F).
  • Vapors can form explosive mixtures with air.
  • Decomposes at high temps, releasing flammable gases (CO, CO₂).

Extinguishing Media

✔ Alcohol-resistant foam
✔ CO₂
✔ Dry chemical powder
✔ Water spray (to cool containers, not direct jet—may spread flames).

Firefighting Precautions

  • Wear SCBA (self-contained breathing apparatus) and full protective gear.
  • Evacuate area—vapors travel and can ignite.
  • Cool nearby containers with water spray to prevent explosion.
  • Do NOT extinguish flames unless leak is stopped (risk of re-ignition).

Spill & Leak Control

  • Small Spills:
    • Neutralize with sodium bicarbonate (baking soda) or calcium carbonate.
    • Absorb with inert material (vermiculite, sand).
    • Dispose as hazardous waste.
  • Large Spills:
    • Evacuate area.
    • Use acid-resistant PPE.
    • Contain spill with barriers (clay, sandbags).
    • Ventilate area to disperse vapors.
