Because acetic acid (CAS 64-19-7) is corrosive and flammable at high concentrations, proper storage is essential for workplace safety, product quality, and regulatory compliance.
Glacial acetic acid/Acetic acid may be unfamiliar to many, but it is actually a very common hazardous chemical. As an indispensable chemical in industry, it has wide applications in many sectors. You may even come into contact with diluted acetic acid at home. Therefore, it is crucial to know how to properly handle this potentially dangerous and corrosive acid. Please follow the safety tips provided by our chemical safety experts.
Common Uses of Acetic Acid
Before explaining the safety recommendations, let's understand which industries use acetic acid raw material.
Ethanoic acid is a colorless liquid with a pungent vinegar odor. High concentrations (99.5% / 99.8%) are called glacial acetic acid. It has wide applications in many industries, including:
- Synthetic vinyl acetate monomer (ultimately used in the production of paints and adhesives)
- Vinegar (diluted acetic acid with a purity of 4-18%)
- Inks, paints, and dyes
- Solvent
- It is also used in the production of many other chemicals, including preservatives, bactericides and pesticides, coatings, and pigments.

Acetic Acid Hazards
Skin and Eye Contact
High-purity acetic acid is highly corrosive. It can cause severe chemical burns to the skin and, if left untreated, may lead to permanent eye damage.
Inhalation
Vapor vapors irritate the respiratory tract. Prolonged or excessive exposure may cause throat swelling, bronchitis, and lung damage.
Swallowing
Swallowing can burn the mouth, throat, and stomach and may cause delayed visceral damage, posing a potential risk.
Fire and Explosion Hazards
It has a flash point of 39°C and is flammable. Its vapors, when heated, may form an explosive air mixture.
How to safely store industrial acetic acid CAS 64-19-7?
For industrial buyers and importers, understanding proper storage methods can reduce operational losses and improve long-term safety.
1. Store in a Cool and Ventilated Area
Store acetic acid liquid in a cool, dry, and well-ventilated warehouse. Avoid direct sunlight and heat sources, and maintain a stable temperature. High temperatures increase vapor pressure and evaporation rate, increasing the risk of fire.
2. Keep Away from All Sources of Ignition
Industrial acetic acid (glacial) is flammable, especially at high concentrations. Therefore, open flames, sparks, smoking, and high-temperature surfaces are strictly prohibited in the storage area. Use explosion-proof electrical equipment and ensure the availability of fire extinguishers and emergency facilities.
3. Prevent moisture
High-purity AA/GAA (CAS 64-19-7) readily absorbs moisture from the air. To maintain its quality stability, you need to keep the container sealed, avoid prolonged exposure of this chemical to humid air, and regularly check that the lid is tight.
Moisture contamination will reduce its purity, chemical properties, and industrial reaction efficiency. This is especially important for glacial acetic acid with a purity of 99.8%.
