Despite its widespread use, glacial acetic acid poses certain hazards. It is classified as a corrosive substance, capable of causing severe burns upon contact with skin and eyes. Inhalation of its vapors can lead to respiratory irritation, making the use of personal protective equipment (PPE) imperative during handling. Adequate ventilation and appropriate storage conditions are also vital to minimize risks.
However, as with any food additive, some individuals may experience sensitivities or allergic reactions. It is always advisable for consumers to read labels and be aware of the ingredients in their food, especially for those with specific dietary restrictions.
