| Hazard category | Class 2.1 Flammable gases | ||
| Fire-fighting measures | Cut off the air source. If the air source cannot be cut off, the flame at the leakage is not allowed to be extinguished. Firefighters must wear air respirators and full-body fire and gas clothing to extinguish the fire in the upwind direction. Move the container from the fire to an open area as much as possible. Spray water to keep the fire vessel cool until the end of the fire extinguishing. Fire extinguishing agent: mist water, foam, dry powder, carbon dioxide. | ||
| Emergency treatment | Inhalation: Quickly leave the scene to fresh air. Keep your airways open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. | ||
| Packaging, storage, transportation | Packaging: Gas cylinder: regular 118L cylinder is filled with about 50KG, ISO tank (24m³), tank truck (58m³) is packed in high-pressure cylinders, and the bottle body is clearly marked. Storage: Store in a cool and ventilated warehouse for flammable gases. Away from fire and heat sources, the storage temperature should not exceed 30°C. It should be stored separately from oxidants and acids, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. 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. Transportation: When transporting cylinders, you must wear a safety helmet on the cylinder. The cylinder is generally laid flat, and the mouth of the bottle should be facing the same direction and should not be crossed; The height shall not exceed the protective fence of the vehicle, and it shall be securely snapped with a triangular wooden mat to prevent rolling. | ||
