| Hazard category | 3.2 Flash point flammable liquids | ||
| Fire-fighting measures | Firefighters must wear gas masks and full-body fire suits and fight the fire from the upwind direction. Try to move the containers to an open area and spray water to cool them down until the fire is extinguished. Fire extinguishing agents: anti-soluble foam, carbon dioxide, dry powder, sand. Water cannot be used to extinguish the fire. | ||
| Emergency treatment |
Skin contact: Take off contaminated clothing and wash skin thoroughly with soap and water. Eye contact: Immediately lift the eyelids, rinse thoroughly with plenty of running water or saline for at least 15 minutes, and seek medical attention. Inhalation: Leave the scene quickly to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention. Ingestion: Drink enough warm water, induce vomiting, and seek medical attention. |
||
| Packaging, storage, transportation | Packing: iron, drum 160kg/drum, also can be tanker bulk; Storage: Cool, ventilated warehouse, warehouse temperature ≤ 20 °C, sealed and protected from light, away from fire and heat sources, stored separately from oxidants, reducing agents, and acids, using explosion-proof lighting, ventilation, and leakage emergency treatment equipment in the warehouse; Transportation: According to the transportation of extremely flammable liquids, tank trucks must be grounded, mixed transportation of contraindicated substances is strictly prohibited, transportation vehicles are equipped with fire-fighting equipment, smoking and fire are strictly prohibited, and transportation in the morning and evening in summer. | ||
