Safety Data Sheet for Glacial Acetic Acid Comprehensive Overview and Handling Guidelines

Safety Data Sheet (SDS) for Glacial Acetic Acid

1. Product Identification

- Chemical Name Glacial Acetic Acid - CAS Number 64-19-7 - Chemical Formula CH₃COOH - Synonyms Ethanoic Acid, Acetic Acid - Application Glacial acetic acid is used in various applications including the production of acetates, as a solvent, in the food industry, and in the manufacturing of various chemicals.

2. Hazards Identification

Glacial acetic acid is classified as a hazardous substance. Key hazards include

- Health Hazards It is highly corrosive and can cause severe skin burns and eye damage. Inhalation of vapor can lead to respiratory tract irritation, cough, and shortness of breath. Prolonged exposure can cause lung edema. - Environmental Hazards If released into the environment, glacial acetic acid can cause damage to aquatic life.

3. Composition/Information on Ingredients

- Substance Glacial Acetic Acid - Concentration ≥ 99% - Impurities Trace amounts of water.

4. First Aid Measures

- Inhalation Move the exposed person to fresh air immediately. If breathing is difficult, provide oxygen. Seek medical attention. - Skin Contact Remove contaminated clothing. Rinse skin with plenty of water for at least 15 minutes. Seek medical attention. - Eye Contact Rinse eyes with water for at least 15 minutes, lifting upper and lower eyelids. Seek immediate medical attention. - Ingestion Do not induce vomiting. Rinse mouth thoroughly with water and seek medical attention.

5. Firefighting Measures

- Flammable Properties Glacial acetic acid has a flash point of 39.5°C (103.1°F). - Extinguishing Media Use alcohol-resistant foam, carbon dioxide (CO₂), or dry chemical extinguishers. - Firefighting Procedures Wear self-contained breathing apparatus (SCBA) and full protective gear. Cool containers with water spray to prevent pressure buildup.

6. Accidental Release Measures

In case of a spill

- Evacuate the area and ensure adequate ventilation. - Wear appropriate personal protective equipment (PPE), including gloves and goggles. - Contain the spill with absorbent materials and collect for disposal in appropriate containers. - Neutralize residual acid with an alkali such as sodium bicarbonate before disposal.

7. Handling and Storage

- Handling Avoid all contact. Use in a well-ventilated area and implement the use of appropriate PPE. Do not eat, drink, or smoke while handling the product. - Storage Store in a cool, dry, well-ventilated area away from incompatible substances like strong bases and oxidizers. Use only approved containers.

8. Exposure Controls/Personal Protection

- Occupational Exposure Limit The exposure limit for glacial acetic acid is typically set at 10 ppm (TWA) in many jurisdictions. - Engineering Controls Provide adequate ventilation and local exhaust to maintain airborne concentrations below established limits. - Personal Protective Equipment - Respiratory Protection NIOSH-approved respirators for airborne exposure. - Skin Protection Wear chemically resistant gloves and protective clothing. - Eye Protection Use safety goggles or face shields.

9. Stability and Reactivity

- Stability Stable under normal conditions. - Conditions to Avoid Heat, flames, and incompatible materials. - Incompatible Materials Strong oxidizers, bases, and reactive metals. - Decomposition Products May produce toxic fumes such as carbon monoxide and carbon dioxide when burned.

10. Ecological Information

Glacial acetic acid is harmful to aquatic life with long-lasting effects. Precaution should be taken to prevent releases to the environment. It is biodegradable but can contribute to the acidity levels in the water bodies.

Conclusion

Glacial acetic acid is an important chemical with a variety of industrial applications. However, its corrosive nature and potential health hazards necessitate strict compliance with safety measures. Manufacturers and users should ensure they are familiar with the contents of the Safety Data Sheet (SDS) and adhere to recommended precautions, including proper handling, storage, and emergency response procedures, to ensure safety and minimize risks associated with its use. Always refer to the most current SDS available for specific product details and safety information.
