How do you storage this product?

This product should be stored in a dry and clean warehouse. Keep away from fire and heat sources. Keep out of direct sunlight and keep the container tightly closed. It should be stored separately from flammable and combustible materials, reducing agents, sulfur, phosphorus, metal powder, etc. Mixed storage and mixed transportation are forbidden. When handling the workers should be lightly loaded and unloaded to prevent damage to packaging and containers.


Spill emergency treatment?

Isolate the leakage pollution area immediately, and set warning signs around it. It is recommended that emergency personnel wear gas masks and chemical protective clothing. Do not directly contact the spill products, do not let the spill contact with combustible substances (wood, paper, oil, etc.), and absorb it with sand, vermiculite or other inert materials, and then collect and transfer to a safe place. In case of a large amount of leakage, collect and recycle or discard after harmless treatment.


Protective measures?

Respiratory system protection: When the concentration in the air is high, a self-priming filter dust mask should be worn. And wear self-contained breathing apparatus if necessary.
Eye Protection: Wear chemical safety goggles.
Body protection: wear tape anti-virus clothing.
Hand Protection: Wear rubber gloves.

The emergency measures.

Skin contact: Take off contaminated clothing, rinse thoroughly with running water immediately.
Eye contact: Immediately lift the eyelids and rinse with running water or saline for at least 15 minutes. Seek medical attention.
Inhalation: Get away from the scene to fresh air. Give artificial respiration if necessary. Seek medical attention.
Ingestion: If swallowed by mistake, drink plenty of warm water, induce vomiting, seek medical attention.
