Acetic acid? is a strong corrosive acid and can be hazardous if not handled properly. Here are some precautions to take when handling acetic acid:

1. Personal protective equipment: Wear appropriate personal protective equipment, including gloves, safety goggles, and protective clothing, to avoid skin and eye contact.
2. Ventilation: Work in a well-ventilated area, as acetic acid vapors, can irritate the respiratory system and cause eye and nose irritation.
3. Handling and storage: Store acetic acid in a cool, dry, well-ventilated area, away from heat sources and incompatible materials. Always handle the chemical with care and use appropriate containers to prevent spills or leaks.
4. Emergency procedures: Know the emergency procedures and first aid measures in case of accidental exposure to acetic acid, such as skin or eye contact, inhalation, or ingestion.
5. Chemical compatibility: Avoid contact with reactive chemicals or incompatible materials, as acetic acid can react with strong bases, oxidizing agents, and metals to release flammable hydrogen gas or cause violent reactions.
6. Disposal: Dispose of acetic acid properly according to local regulations and guidelines.

Always follow the manufacturer’s instructions, safety data sheets (SDS), and other relevant safety information when handling acetic acid or any hazardous chemical.
