| Fire-fighting measures | This product does not burn, and the focus is on cooling the container with spray water in case of fire to prevent the container from exploding due to heat; Firefighters wear gas masks to extinguish the fire in the upwind direction to avoid inhaling toxic gases decomposed at high temperatures; Never inject water directly into the container to prevent cryogenic liquid splashing. | ||
| Emergency treatment | Inhalation: Immediately transfer to a non-contaminated area, keep the airway open, artificial respiration/ventilator if breathing stops, oxygen infusion for dyspnea, and seek medical supervision as soon as possible. Skin contact: If contact with liquid products causes frostbite, rinse slowly with warm water at 41-46°C, avoid hot water, lightly wrap the wound with a strap, and seek medical attention immediately; Eye contact: Rinse with running water for at least 15 minutes and seek medical supervision immediately; Ingestion: If ingested in large quantities, seek medical supervision immediately. | ||
| Packaging, storage, transportation | Packing: High pressure cylinder, regular specification 40L/cylinder; Storage: Cool, ventilated warehouse, storage temperature ≤ 25°C, away from fire and heat sources, stored separately from metals, flammables, and oxidants, and handled gently to prevent damage; Transportation: Transport according to non-flammable toxic liquids/gases, light loading and unloading, to prevent cylinders/barrels from colliding, transport vehicles are equipped with emergency protection equipment, and it is strictly forbidden to mix with metal powder. | ||
