| Fire-fighting measures | Extinguish the fire with foam, carbon dioxide, dry powder, sand, water extinguishing is ineffective, spray water to cool the container, and if possible, move the container from the fire to an open place. Containers in the fire must be evacuated immediately if they have changed color or produced sound from the safety pressure relief device | ||
| Emergency treatment | Skin contact: Remove contaminated clothing and rinse the skin thoroughly with soapy water and clean water. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of running water or saline for at least 15 minutes. 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. Eating: Drink enough warm water to induce vomiting. Seek medical attention. | ||
| Packaging, storage, transportation | Packaging: Packed in galvanized iron drums, each barrel has a net weight of 140kg, and can also be transported by stainless steel tank truck. Storage: Store in a cool, ventilated warehouse. Stay away from fire and heat sources. The cooling temperature should not exceed 29°C. Keep the container tightly sealed. It should be stored separately from the oxidizing agent and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are prone to sparks. Transportation: Transportation according to the requirements of dangerous goods | ||
