| Fire-fighting measures | Firefighters must wear acid and alkali resistant firefighting suits and wear air respirators to extinguish fires in the upwind direction. Neutralize with alkaline substances such as sodium bicarbonate, sodium carbonate, slaked lime, etc. It can also be extinguished with a large amount of water. When extinguishing fires, try to cut off the source of leakage to prevent it from flowing into restricted spaces such as sirlines and drainage ditches. | ||
| Emergency treatment | Skin contact: Remove contaminated clothing immediately and rinse with plenty of running water for at least 15 minutes. Seek medical attention. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention. Inhalation: Quickly leave the scene to fresh air. Keep your airways open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. Food: Rinse your mouth with water and give milk or egg white. Seek medical attention. | ||
| Packaging, storage, transportation | Packing: 180kg / plastic drum / acid-resistant jar, IBC ton drum. Storage: Store in a cool, ventilated warehouse. The storage temperature does not exceed 30°C and the relative humidity does not exceed 85%. Keep the container tightly sealed. It should be stored separately from alkalis, amines, alkali metals, flammable materials or combustibles, and should not be mixed storage. The storage area should be equipped with leak emergency treatment equipment and appropriate containment materials. Transportation: This product is a class 3 precursor product and is transported in strict accordance with the requirements of dangerous goods. | ||
