Emergency treatment

Skin contact: Immediately remove contaminated clothing, rinse the skin thoroughly with soapy water and water, and seek medical attention; Eye contact: lift the eyelids immediately, rinse thoroughly with plenty of running water or saline for at least 15 minutes, and seek medical attention; Inhalation: Quickly leave the scene to a fresh place in the air, keep the airway open, and seek medical attention;

Packaging, storage, transportation

Packaged as high-pressure cylinders and low-temperature storage tanks; Regular specifications: 40L high-pressure cylinder (filling capacity about 25kg); The cylinder is made of seamless carbon cylinder, with special valves and pressure reducing valves, stored in a cool and ventilated special warehouse for flammable gas, and the storage temperature should not exceed 30 °C, away from fire and heat sources. The cylinder should be placed upright and fixed with a clamp to prevent tipping over, and stored separately from oxidizers, acids and alkalis. The warehouse adopts explosion-proof lighting and ventilation facilities, and it is forbidden to use mechanical equipment and tools that are prone to sparks; The storage area should be equipped with leakage emergency treatment equipment; Transported according to the requirements of dangerous goods
