emergency treatment

first-aid

Skin contact: Take off contaminated clothing, wash skin thoroughly with soap and water.

Eye contact: Immediately lift the eyelids and rinse with plenty of flowing water or saline for at least 15 minutes. Seek medical attention.

Inhalation: Quickly leave the scene to fresh air. Keep airway open. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately. Seek medical attention.

Ingestion: Drink plenty of warm water, induce vomiting.

Leakage emergency treatment

Quickly evacuate the personnel in the leaked contaminated area to a safe area, and isolate them, strictly restricting access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static overalls. Cut off the source of the leak as much as possible. Prevent flowing into restricted spaces such as sewers and flood drains.

Small spills: Absorb with activated carbon or other inert material. It can also be washed with a large amount of water, and the washed water is diluted and put into the waste water system.

Large amount of leakage: Construct dikes or dig pits for containment. Cover with foam to reduce vapor hazards. Use an explosion-proof pump to transfer to a tank truck or a special collector, recycle or transport to a waste disposal site for disposal.

Handling and Storage

Handling Precautions: Airtight operation, full ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety protective glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from escaping into workplace air. Avoid contact with oxidants, acids, and alkalis. The flow rate should be controlled during filling, and there should be a grounding device to prevent static electricity from accumulating. When handling, load and unload lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30°C. Keep container tightly closed. It should be stored separately from oxidants, acids, and alkalis, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
