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.
