Hazard category

2.1 Class flammable gas

Fire-fighting measures

Spray water to cool the container, and move the container from the fire scene to an open place if possible. The gas is heavier than air and can spread to a considerable distance at a lower place, and will ignite when it encounters a fire source. Extinguishing agent: water mist, foam, carbon dioxide, dry powder

Emergency treatment

Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention

Packaging, storage, transportation

Steel cylinders (118L, 400L, 800L, 926L), ISO tank, tank truck, stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature does not exceed 30℃, and the relative humidity does not exceed 80%. Transport as required by dangerous goods
