Safety Data Sheet (SDS) for Glacial Acetic Acid

1. Product Identification Glacial acetic acid, chemically known as ethanoic acid (CH₃COOH), is a colorless liquid with a strong vinegar-like odor. It is a key industrial chemical and serves as a solvent, a reagent in organic synthesis, and is widely used in the production of various chemical compounds. The substance is referred to as glacial because it solidifies at temperatures of about 16.6 °C (62 °F), forming a crystalline solid.

2. Composition and Composition Information The primary component of glacial acetic acid is acetic acid itself, typically present in concentrations of at least 99.5%. It may contain trace amounts of water and other impurities depending on the manufacturing process.

3. Hazard Identification Glacial acetic acid is classified as a corrosive substance. It poses several health risks - Skin and Eye Contact It can cause severe burns and permanent damage to tissues upon contact. - Inhalation Inhaling vapors can cause respiratory tract irritation, leading to severe respiratory distress. - Ingestion It is highly toxic if swallowed, potentially leading to nausea, vomiting, and more severe gastrointestinal issues.

4. First-Aid Measures In case of exposure - Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes and seek medical help. - Skin Contact Remove contaminated clothing and rinse affected skin with water. Seek medical attention if irritation persists. - Inhalation Move to fresh air immediately. If breathing is difficult, seek emergency medical assistance. - Ingestion Do not induce vomiting. Rinse mouth and seek medical attention immediately.

5. Fire-Fighting Measures Glacial acetic acid is flammable and can ignite if exposed to heat or open flames. In the event of a fire - Use water spray, foam, dry chemical, or carbon dioxide to extinguish flames. - Wear appropriate protective equipment including self-contained breathing apparatus when fighting chemical fires.

6. Accidental Release Measures In the case of a spill - Evacuate the area and ensure good ventilation. - Wear appropriate protective equipment, including gloves and goggles. - Contain the spill using inert materials like sand or earth and avoid water contact. - Dispose of the collected material according to regulations.

7. Handling and Storage When handling glacial acetic acid - Use in a fume hood or well-ventilated area to avoid inhalation of vapors. - Wear respiratory protection, chemical goggles, and gloves resistant to acids. - Store in a cool, dry, well-ventilated area away from incompatible substances, such as strong oxidizers.

8. Exposure Controls and Personal Protection The recommended exposure limits for glacial acetic acid are - OSHA PEL 10 ppm (TWA) - ACGIH TLV 10 ppm (TWA), 15 ppm (STEL)

Use appropriate engineering controls, such as local exhaust ventilation, along with personal protective equipment (PPE), including gloves and safety goggles.

9. Physical and Chemical Properties - Appearance Colorless liquid - Odor Pungent, vinegar-like - Boiling Point 118 °C (244 °F) - Melting Point 16.6 °C (62 °F) - Solubility Miscible with water, ethanol, and ether

10. Stability and Reactivity Glacial acetic acid is stable under normal conditions but can react violently with strong oxidants or bases. Heat, sparks, or flames can initiate combustion.

Conclusion Glacial acetic acid is a powerful industrial chemical that requires careful handling due to its hazardous nature. Understanding its properties, potential health risks, and safety measures outlined in the Safety Data Sheet is essential for anyone who works with or around this substance. Proper training and adherence to safety regulations can mitigate risks and ensure a safer working environment. Always consult the Safety Data Sheet before use to be informed about all safety protocols.
