Safety Data Sheet (SDS) for Glacial Acetic Acid

Introduction

Glacial acetic acid is a colorless liquid with a pungent odor, widely utilized in various industrial and laboratory applications. It is a vital ingredient in the production of acetic anhydride, acetate esters, and acetic acid derivatives. Given its widespread use, understanding its properties, handling procedures, and safety measures is crucial. This article provides an overview of glacial acetic acid, focusing on its Safety Data Sheet (SDS) details.

Chemical Properties

Glacial acetic acid is the pure form of acetic acid, containing about 99% acetic acid and only a small amount of water. Its chemical formula is C2H4O2, and its molecular weight is 60.05 g/mol. It has a boiling point of 118 °C and a freezing point of 16.6 °C, which is significant as it can solidify at low temperatures. In industrial settings, it is essential to note that the substance is hygroscopic, absorbing moisture from the environment, which can affect its concentration.

Physical and Chemical Hazards

The SDS for glacial acetic acid categorizes it as a flammable liquid and a corrosive substance. Its flash point is around 39 °C (102 °F), making it a fire risk, especially when exposed to open flames or high temperatures. The vapors can form explosive mixtures with air, and direct contact can cause severe burns to skin and damage to eyes. Inhalation of vapors can lead to respiratory issues and irritation to the mucous membranes.

Health Hazards

Exposure to glacial acetic acid may occur through inhalation, skin contact, or ingestion. Symptoms of exposure can manifest as

- Skin Burns, redness, and irritation. - Eyes Severe irritation, redness, and potential for permanent damage. - Inhalation Coughing, irritation of the respiratory tract, and pulmonary edema in severe cases. - Ingestion Corrosive damage to the mouth, throat, and stomach.

Chronic exposure can result in long-term respiratory issues and skin sensitization. Therefore, it is essential to use personal protective equipment (PPE) to mitigate these risks.

First-Aid Measures

In case of exposure, appropriate first-aid measures should be taken immediately

- Skin Contact Remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. Seek medical attention if irritation persists. - Eye Contact Rinse immediately with water for at least 15 minutes while holding eyelids open. Seek medical attention promptly. - Inhalation Move the affected person to fresh air. If symptoms persist, seek medical assistance. - Ingestion Do not induce vomiting. Rinse the mouth and seek medical attention immediately.

Handling and Storage

When handling glacial acetic acid, it is imperative to follow strict safety protocols

1. Personal Protective Equipment (PPE) Users should wear safety goggles, gloves resistant to acetic acid, and lab coats. Use appropriate respiratory protection in poorly ventilated areas. 2. Work Environment Ensure work areas are well-ventilated. Avoid open flames, sparks, and other ignition sources.

3. Storage Store glacial acetic acid in a cool, dry place in a tightly sealed container. It should be kept away from oxidizing agents, bases, and metals to prevent corrosive reactions.

Emergency Measures

In case of a spill, it is vital to have emergency procedures in place. Use appropriate materials to absorb spills, such as non-combustible absorbents. Ensure that the area is ventilated and restrict access to the spill site until it is cleaned. Dispose of waste according to local regulations.

Conclusion

Glacial acetic acid is a versatile and essential chemical widely employed in various industries. However, due to its hazardous nature, proper knowledge of its properties, safety measures, and appropriate response actions in case of exposure are paramount. By adhering to the guidance provided in its Safety Data Sheet (SDS), workers and researchers can help mitigate risks and handle glacial acetic acid safely in their environments. Always prioritize safety and be prepared to act in case of emergencies.
