1. Identification of chemicals and enterprises;

Chemical Chinese name: formic acid; Formic acid;

Chemical name: formic acid; methanoic acid;

Molecular formula: CH2O2;

Relative molecular weight: 46.03;

2. Composition and composition information;

Composition: formic acid;

CAS No: 64-18-6;

3. Overview of risks;

Danger category: 8.1 acid corrosion products;

Invasion route: inhalation, ingestion;

Health hazard: mainly cause skin, mucous membrane irritation symptoms. After exposure can cause conjunctivitis, eyelid edema, rhinitis, bronchitis, severe cases can cause acute chemical pneumonia. When taken orally, concentrated formic acid can corrode the mucosa of the mouth and digestive tract, causing vomiting, diarrhea, gastrointestinal bleeding, and even death due to acute renal failure or respiratory failure. Skin contact can cause inflammation and ulcers. Occasionally have allergic reactions.

Harmful to the environment;

Explosion hazard: flammable, its vapor mixed with air, can form an explosive mixture.

4. First aid measures;

Skin contact: immediately remove contaminated clothing and rinse with plenty of flowing water for 20-30min. If you feel uncomfortable, seek medical attention.

Eye contact: Lift eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for 10~15min. If you feel uncomfortable, seek medical attention.

Inhalation: Quickly remove from the scene to fresh air. Keep your airway clear. Give oxygen if breathing is difficult. If breathing and heart stop, perform CPR immediately. Seek medical attention.

To ingest: Gargle with water and drink milk or egg whites. No emetic. Seek medical attention.

5. Fire control measures;

Hazard characteristics: flammable. Its vapor and air can form explosive mixture, in the case of open fire, high heat easy combustion explosion. Chemical reactions can occur in contact with strong oxidants. It is highly corrosive.

Harmful combustion products: carbon monoxide;

Extinguishing method: Use soluble foam, carbon dioxide, dry powder to extinguish fire.
