Uses Methanol is widely used as a basic organic chemical raw material and high-quality fuel. Mainly used in fine chemicals, plastics and other fields to produce organic products such as formaldehyde, acetic acid, methyl chloride, methylamine, dimethyl sulfate, etc. It is a raw material for pesticides and pharmaceuticals. Methanol can be used as a new clean fuel after deep processing, and it can be added to gasoline for mixing.
Hazard category 3.2 Class flammable liquid
Fire-fighting measures Warehouse: ventilated, low temperature and dry; stored separately from oxidants and acids. Use alcohol-resistant foam, dry powder, carbon dioxide, and sand to extinguish the fire.
Emergency treatment Inhalation: quickly leave the scene to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.   Ingestion: Drink enough warm water to induce vomiting. Lavage the stomach with water or 1% sodium thiosulfate solution. Seek medical attention. Skin contact: Take off contaminated clothing and rinse the skin thoroughly with soap and water. Eye contact: Lift the eyelid and rinse with running water or normal saline. Seek medical attention.
