Spill emergency treatment?

Isolate the leakage pollution area, and set warning signs around it. It is recommended that emergency personnel wear self-contained breathing apparatus and chemical protective clothing. Flush contaminated area with copious amounts of water and place diluted sewage into waste water system. It can also be carefully swept up to avoid dust and transported to a waste disposal site. In case of a large amount of leakage, collect and recycle or discard after harmless treatment.

Handling and storage?

Operation precautions: Airtight operation, local exhaust. Prevent dust from being released into the workshop air. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti-poison infiltration overalls, and rubber gloves. Avoid the generation of dust. Avoid contact with oxidizing agents and alkali metals. Equipped with leakage emergency treatment equipment. Empty containers may contain hazardous residues.

Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep out of direct sunlight. The package is sealed.
