| 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. | ||
| Packaging, storage, transportation | It can be packed in baking painted iron drum, 160KG/drum, stored in a cool, well-ventilated special warehouse, away from fire and heat sources; the warehouse temperature should not exceed 37℃, keep the container sealed; it should be stored separately from oxidants, acids, alkali metals, etc. , Avoid mixed storage; use explosion-proof lighting and ventilation facilities ; prohibit the use of mechanical equipment and tools that are prone to sparks; storage areas should be equipped with leakage emergency treatment equipment and suitable storage materials. Transportation should be done in the morning or evening in the hot season. | ||
