Material Safety Data Sheet (MSDS) for Glacial Acetic Acid

Glacial acetic acid, chemically known as ethanoic acid, is a clear, colorless liquid with a pungent, vinegary smell. It is a key industrial chemical and is widely used in a variety of applications, including the production of synthetic fibers, plastics, and food preservatives. However, due to its corrosive nature and potential health hazards, it is essential to understand and adhere to its Material Safety Data Sheet (MSDS).

1. Identification

Glacial acetic acid is classified under the chemical formula C2H4O2 and has a molecular weight of 60.05 g/mol. It is important to note that the term glacial indicates its relatively high concentration (greater than 99%) and tendency to freeze at low temperatures, forming ice-like crystals.

2. Hazards

According to the MSDS, glacial acetic acid is categorized as a corrosive substance. Direct contact with skin or eyes can result in severe burns, while inhalation of vapors may lead to respiratory irritation, coughing, and difficulty breathing. Prolonged exposure can cause damage to mucous membranes and lungs. The chemical can also pose environmental risks, as it is harmful to aquatic life.

3. Handling and Storage

When handling glacial acetic acid, it is crucial to wear appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection. It should be stored in a cool, well-ventilated area, away from incompatible materials like strong bases, oxidizers, and flammable substances. Containers should be tightly sealed and clearly labeled to avoid accidental exposure.

4. Emergency Measures

In the event of exposure, immediate actions should be taken. For skin contact, the affected area should be flushed with plenty of water for at least 15 minutes, while contaminated clothing should be removed. If splashed in the eyes, they should be rinsed thoroughly with water and medical attention sought immediately. In case of inhalation, the person should be moved to fresh air and given medical assistance if symptoms persist.

5. Conclusion

Glacial acetic acid is a versatile chemical with important applications across various industries. However, its corrosive properties necessitate strict adherence to safety guidelines as outlined in its MSDS. Awareness and understanding of proper handling, potential hazards, and emergency procedures are essential for ensuring safety in environments where glacial acetic acid is used or stored. Always refer to the MSDS for the most accurate and comprehensive safety information.
