The harm of glacial acetic acid to human body
time:2019-07-22 15:51:35click:788

  Glacial acetic acid is an organic monic acid, which is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid. Its aqueous solution is mildly acidic and highly corrosive. It is mainly used in vinyl acetate, acetic anhydride, acetate fiber, acetate and metal acetate.

Glacial acetic acid is highly corrosive and harmful to human body. It can cause skin burn, permanent blindness and inflammation of mucous membrane. Therefore, appropriate protection is needed. Special gloves, such as nitrile butadiene rubber gloves, should be worn when handling glacial acetic acid. Concentrated glacial acetic acid is difficult to burn in the laboratory, but it becomes flammable at ambient temperatures of 39 ° c (102 ° f), where it can explode with air. Because of its pungent odor and corrosive vapors, acetic acid at concentrations greater than 25% should be administered under an eye mask.

First aid measures:

If in contact with skin, rinse with water before washing thoroughly with soap. In case of contact with eyes, rinse with water and wipe with dry cloth. If inhaling steam, the patient should be removed from the contaminated area, rest and keep warm. If accidentally swallowed immediately gargle, give emetic to induce vomiting, urgent hospital treatment.

Protective measures:

It is recommended that operators wear self-suction filter gas mask (half mask), chemical safety protection glasses, acid and alkali resistant plastic overalls, and rubber acid and alkali resistant gloves. Keep away from fire and heat sources. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidant and alkali.
