Safety Data Sheet for Glacial Acetic Acid Handling and Use Guidelines

Safety Data Sheet (SDS) for Glacial Acetic Acid

Introduction

Glacial acetic acid is a colorless liquid organic compound with a distinctive vinegar-like smell and a strong acidic taste. It is a key chemical used in various industrial applications, including the production of synthetic fibers, plastics, and food additives. Due to its corrosive nature and potential hazards, it is essential to understand the safety measures and practices necessary when handling glacial acetic acid, as outlined in its Safety Data Sheet (SDS).

Chemical Identification

- Product Name Glacial Acetic Acid - CAS Number 64-19-7 - Molecular Formula CH₃COOH - Purity 99% or higher

Hazards Identification

Glacial acetic acid poses several hazards which are clearly defined in the SDS. The key hazards include

1. Corrosivity It is a strong acid that can cause severe burns and damage to skin, eyes, and respiratory tract upon contact or inhalation. 2. Flammability It is flammable, and its vapors can form explosive mixtures with air. The flash point is approximately 39°C (102°F). 3. Environmental Impact It may cause long-term adverse effects in the aquatic environment.

First Aid Measures

1. Skin Contact Remove contaminated clothing. Rinse the affected area with plenty of water for at least 15 minutes and seek medical attention. 2. Eye Contact Rinse eyes cautiously with water for several minutes, ensuring that contact lenses are removed. Seek immediate medical attention. 3. Inhalation Move to fresh air. If breathing is difficult, administer oxygen and seek medical help. 4. Ingestion Do not induce vomiting. Rinse the mouth with water and seek medical attention.

Handling and Storage

When handling glacial acetic acid, implement appropriate safety precautions

- Personal Protective Equipment (PPE) Wear appropriate gloves, goggles, and protective clothing to prevent skin and eye contact. - Ventilation Use in a well-ventilated area or a fume hood to limit inhalation of vapors. - Storage Store in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers and bases. Ensure containers are properly labeled and sealed.

Fire Fighting Measures

In the event of a fire involving glacial acetic acid, follow these guidelines

- Extinguishing Media Use alcohol-resistant foam, carbon dioxide, dry chemical powder, or water spray for cooling and extinguishing. - Fire Fighting Procedures Firefighters should wear self-contained breathing apparatus and full protective gear. Evacuation of the area should be considered due to toxic fumes.

Accidental Release Measures

In case of a spill or leak, it is vital to act swiftly and safely

1. Personal Precautions Ensure adequate ventilation and use appropriate PPE. 2. Containment Contain the spill using inert absorbent materials, such as sand or vermiculite. 3. Cleanup Dispose of the collected materials according to local regulations. Ensure that the area is thoroughly cleaned to prevent further hazards.

Environmental Considerations

Prevent releases and spills of glacial acetic acid into the environment. In case of a spill that may enter waterways, notify local environmental authorities immediately. Due to its potential to cause environmental harm, special care must be taken to follow all regulations regarding its disposal.

Conclusion

Understanding the properties and dangers associated with glacial acetic acid is vital for ensuring safety in industrial and laboratory environments. Proper use of the Safety Data Sheet and adherence to recommended safety measures can prevent accidents and injuries related to this hazardous substance. Always stay informed, and prioritize safety when working with glacial acetic acid or any other potentially dangerous chemicals.
