Package

Net weight per bucket is 25 kg or 50 kg in cardboard bucket. 

Storage

Closed operation to provide adequate local exhaust. Prevent dust from releasing into the workshop air. Operators must undergo special training and strictly follow the operating procedures. It is recommended that the operator wear a dust mask (overall cover), penetrate the gas type respirator, and wear rubber gloves. Avoid dust. Avoid contact with oxidants. Equipped with emergency disposal equipment for leakage. Empty containers may leave harmful substances. Store in a cool, airy warehouse. Keep away from fire and heat. Keep the sun from direct sunlight. Package seal. Should be stored separately with oxidants, shall not be mixed storage. The reservoir shall be provided with suitable materials for the leakage...
