Safety Data Sheet for Concentrated Acetic Acid in its Glacial Form

Understanding Glacial Acetic Acid Safety Data Sheet (SDS) Overview

Glacial acetic acid, chemically known as ethanoic acid, is a colorless liquid organic compound with a pungent smell and a sour taste. It is the main component of vinegar, which generally contains about 5-20% acetic acid. When referring to glacial acetic acid, we denote the pure form, which is concentrated, typically containing over 99% acetic acid. This compound is widely used in various industries including food production, pharmaceuticals, and chemical manufacturing. Due to its corrosive nature and potential health hazards, a Safety Data Sheet (SDS) is crucial for understanding the safe handling, storage, and disposal of glacial acetic acid.

Chemical Properties

Glacial acetic acid has a molecular formula of C2H4O2, with a molecular weight of 60.05 g/mol. It has a boiling point of about 118.1°C (244.6°F) and a melting point of 16.6°C (61.88°F), which classifies it as a liquid at room temperature. Its properties include being hygroscopic, meaning it can absorb water from the environment. Glacial acetic acid is highly soluble in water and many organic solvents, making it a versatile reagent in laboratories and industries.

Hazards Identification

The SDS for glacial acetic acid highlights several potential hazards

1. Health Hazards Exposure to glacial acetic acid can result in severe irritation to the eyes, skin, and respiratory system. Inhalation of vapors can cause coughing, shortness of breath, and throat irritation. Prolonged contact can lead to chemical burns of the skin and eyes, potentially resulting in permanent damage.

2. Physical Hazards It is classified as a combustible liquid and can create flammable vapors. It has a flash point of approximately 39.5°C (103.1°F), making it necessary to ensure proper ventilation and avoid open flames in areas where glacial acetic acid is used.

3. Environmental Hazards Glacial acetic acid can be harmful to aquatic life, and its release into the environment should be avoided. It can lead to changes in pH levels in water bodies, potentially disrupting ecosystems.

When working with glacial acetic acid, it is essential to implement appropriate safety measures

- Personal Protective Equipment (PPE) Workers should wear protective clothing, including gloves, goggles, and face shields to prevent skin and eye contact. Respiratory protection may also be required in poorly ventilated areas or when handling the substance in larger quantities.

- Engineering Controls Ensure proper ventilation in workspaces. Fume hoods or local exhaust systems should be installed to minimize inhalation of harmful vapors.

- Safe Storage Glacial acetic acid should be stored in tightly closed containers made of compatible materials, such as glass or certain plastics. It should be kept away from heat sources, oxidizing agents, and strong bases.

Emergency Procedures

In the event of a spill or exposure, the SDS outlines specific procedures

- Spills Evacuate the area and ventilate to disperse vapors. Use inert absorbents like sand or vermiculite to contain and clean up the spill. Dispose of the waste according to local regulations.

- First Aid Measures If glacial acetic acid comes into contact with skin, it should be removed promptly using plenty of water. In case of eye exposure, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move the individual to fresh air and seek medical aid if symptoms persist.

Conclusion

Glacial acetic acid is a vital compound in various applications, yet its hazardous nature necessitates a thorough understanding of safety protocols. By adhering to the guidelines provided in the SDS, individuals can significantly reduce the risks associated with its use, ensuring a safer working environment. It is imperative for anyone working with glacial acetic acid to be informed and trained in safety practices to protect themselves and their surroundings.
