| Fire-fighting measures | flammable in open flame and high heat; It is decomposed by heat to produce harmful gases such as carbon monoxide and carbon dioxide. When there is a fire around you, use fire extinguishing agents suitable for the surrounding fire situation (such as mist water, foam, dry powder, carbon dioxide). | ||
| Emergency treatment | Skin contact: Remove contaminated clothing and rinse with running water. Eye contact: lift the eyelid and rinse with running water or saline. Seek medical attention. Inhalation: Leave the scene to fresh air. Seek medical attention. Eating: Drink enough warm water to induce vomiting. Seek medical attention. | ||
| Packaging, storage, transportation | Liquids are usually packaged in clean and dry plastic drums, with specifications of 20kg/drum, 25kg/drum or 200kg/drum; Solid products (waxy/sheet) are packaged in composite plastic woven bags or cardboard drums, and the common specifications are 20kg/bag or 25kg/bag. Store in a cool, dry and ventilated warehouse, sealed and stored, moisture-proof and sun-proof. Keep away from fire and heat sources, and store separately from oxidizers. Transported as a general chemical. During transportation, it should be protected from sun exposure, rain, and high temperature; it is strictly forbidden to mix and transport with oxidants and edible chemicals; Load and unload lightly during loading and unloading to prevent packaging damage. Transportation according to general cargo requirements | ||
