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

Safety Data Sheet for Glacial Acetic Acid

Introduction Glacial acetic acid is a colorless liquid organic compound with a pungent odor, widely used in various industrial applications. As a key ingredient in the production of synthetic fibers, plastics, and food additives, it is essential to handle this chemical with care due to its hazardous nature. This article aims to provide an overview of the Safety Data Sheet (SDS) for glacial acetic acid, emphasizing its physical properties, hazards, handling precautions, and emergency measures.

Physical and Chemical Properties Glacial acetic acid has the chemical formula CH₃COOH and a molecular weight of 60.05 g/mol. The substance features a melting point of 16.6 °C, boiling point of 118 °C, and a density of 1.05 g/cm³. It is miscible in water, ethanol, and ether, allowing for a wide range of applications. The compound is a weak acid but can cause severe burns and tissue damage upon contact with skin or eyes.

Hazards Identification Glacial acetic acid is classified as a hazardous substance under various regulations, such as OSHA and the Globally Harmonized System (GHS). Key hazards associated with glacial acetic acid include

1. Corrosivity It can cause severe skin and eye burns. Prolonged exposure can lead to irreversible damage to body tissues. 2. Health Hazards Inhalation of vapors can lead to respiratory tract irritation, and high concentrations may cause pulmonary edema. Ingestion can result in gastrointestinal corrosion and potential fatal outcomes. 3. Flammability Glacial acetic acid is flammable, with a flash point of 39 °C. It can produce flammable vapors that may ignite in the presence of an open flame or spark.

Handling and Storage To ensure safe handling and storage of glacial acetic acid, several precautions must be observed

1. Personal Protective Equipment (PPE) Always wear appropriate PPE, including gloves, goggles, and protective clothing. A face shield is recommended when working with large quantities. 2. Ventilation Ensure adequate ventilation in areas where glacial acetic acid is used. Use fume hoods if working with large volumes to minimize inhalation risks. 3. Storage Conditions Store glacial acetic acid in a cool, dry, and well-ventilated area, away from incompatible materials such as strong bases and oxidizers. Use appropriate containment cabinets made of compatible materials.

Emergency Measures In the event of an accident involving glacial acetic acid, take immediate action as follows

1. Skin Contact Rinse affected skin with plenty of water for at least 15 minutes while removing contaminated clothing. Seek medical attention promptly. 2. Eye Contact Flush eyes with water or saline for at least 15 minutes, lifting eyelids occasionally. Obtain medical assistance immediately. 3. Inhalation Move the affected individual to fresh air. If breathing is difficult, provide oxygen and seek emergency medical help. 4. Spill Response Evacuate the area, wear appropriate PPE, and absorb spills using inert materials. Dispose of the absorbed material in accordance with local regulations.

Conclusion Understanding the risks associated with glacial acetic acid is crucial for anyone working with this chemical. The Safety Data Sheet (SDS) serves as a vital resource, providing essential information on the substance’s properties, hazards, safe handling practices, and emergency procedures. By adhering to these guidelines, you can minimize risks and ensure a safer working environment when dealing with glacial acetic acid. Remember, safety is paramount when working with any chemical, and proper precautions can prevent accidents and injuries. Always be prepared and informed about the materials you handle in your workplace.
