One of the primary routes of exposure to glacial acetic acid is through inhalation or dermal contact, highlighting the importance of proper handling and appropriate safety protocols in environments where GAA is used. Even minimal exposure can lead to severe health effects. When inhaled, vapors can irritate the respiratory tract, leading to symptoms such as coughing, sore throat, and shortness of breath. Prolonged exposure can result in chemical pneumonitis or even pulmonary edema, a potentially life-threatening condition.

Storage of concentrated ethanoic acid is also critical. It should be kept in tightly sealed containers made of compatible materials, such as glass or specific types of plastic, stored away from heat sources and incompatible substances, such as oxidizing agents. Labeling the contents clearly and ensuring that safety data sheets (SDS) are readily available is essential for workplace safety.

In addition, glacial acetic acid is essential in the production of various chemical intermediates, such as acetic anhydride and various acetates. Acetic anhydride is widely used in the synthesis of pharmaceuticals and other organic compounds, while acetates are utilized in food preservation, as well as in the production of solvents and anti-freeze products.

Plasmid isolation is a fundamental procedure in molecular biology that enables scientists to extract and purify plasmids—small, circular DNA molecules found in bacteria. These plasmids are crucial for cloning, gene expression, and various other biotechnological applications. Among the several methods employed for plasmid isolation, the use of glacial acetic acid plays a significant role, particularly during the alkaline lysis process.
