First-aid measures
Skin contact: Remove contaminated clothing, rinse with water.
Eye contact: Lift the eyelid, rinse with running water or saline. Medical treatment.
Inhalation: From the scene to the fresh air. If breathing is difficult, give oxygen. Medical treatment.
Ingestion: Drink plenty of warm water, vomiting. Medical treatment.
Leakage emergency treatment
Isolated from contaminated areas, restricted access. Recommended emergency personnel wearing a dust mask (full cover), wear protective clothing. To avoid dust, carefully swept away, placed in the bag transferred to a safe place. If a lot of leakage, covered with plastic cloth, canvas. Collected or transported to waste disposal sites.
Operation Precautions
Closed operation, partial exhaust. Operators must be specially trained to strictly observe the operating procedures. It is recommended that the operator wear a self-priming filter dust mask, wear chemical safety glasses, wear anti-penetration work clothes, wear rubber gloves. Avoid dust. Avoid contact with the reducing agent, alkali metal. Handling light loading and unloading, to prevent damage to the packaging. Equipped with a leak emergency treatment equipment. Empty containers may be harmful residues.
Storage precautions
Store in a cool,ventilated warehouse.Away from fire and heat source.Separated from reducing agent,alkali metal and edible chemicals,avoid by all means.Storage area should prepare right materials for leakage.
