Emergency treatment of leakage

Emergency treatment: Evacuate the personnel in the leakage contaminated area to the safe area, prohibit irrelevant personnel from entering the contaminated area, and it is recommended that emergency treatment personnel wear gas masks and chemical protective clothing. Absorb with sand, vermiculite or other inert materials, collect and transport to the waste disposal site. It can also be scrubbed with an emulsion made of non-flammable dispersant, and the diluted washing water is put into the wastewater system. If a large amount of leakage occurs, use the dike to contain it, and then collect, transfer, recycle or harmlessly treat it before discarding.

Operation, disposal and storage

Operation precautions: Closed operation, local exhaust. Prevent vapor from leaking into the air in the workplace. 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, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Do not weld, cut, or perform other operations before removing liquids and vapors. Avoid generating smoke. Avoid contact with oxidants. Equip with appropriate types and quantities of firefighting equipment and leak emergency treatment equipment. Empty containers may contain harmful substances.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Prevent direct sunlight. Keep the container sealed. Store separately from oxidants and edible chemicals, and avoid mixing. Equip with appropriate types and quantities of firefighting equipment. The storage area should be equipped with leak emergency treatment equipment and appropriate containment materials.
