Leakage emergency treatment

Announce
edit
Evacuate the personnel in the leakage contaminated area to the windward place quickly, isolate them, and strictly restrict access. Cut off the ignition source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the leakage source as much as possible. Cover the sewer and other places near the leakage point with industrial coating or adsorption/absorbent to prevent gas from entering. Reasonable ventilation to accelerate diffusion. If there is no danger, burn on the spot, and spray water to cool the surroundings to prevent other combustibles from catching fire. Or move the leaking container to an open place and pay attention to ventilation. Leaking containers shall be properly treated, repaired and inspected before reuse. [1]

Handling and storage

Announce
edit
Precautions for operation: closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. Keep away from kindling and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas leakage into the air of the workplace. Avoid contact with oxidants and halogens. During transmission, the cylinder and container must be grounded and bridged to prevent static electricity. Load and unload gently during transportation to prevent damage to packaging and containers. Fire fighting equipment and leakage emergency treatment equipment of corresponding types and quantities shall be provided.
Precautions for storage: store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The warehouse temperature should not exceed 30 ℃. It shall be stored separately from oxidants and halogens, and mixed storage is strictly prohibited. Explosion proof lighting and ventilation facilities shall be adopted. It is prohibited to use mechanical equipment and tools that are easy to generate sparks. The storage area shall be equipped with leakage emergency treatment equipment.
