Properties and stability
1. Avoid contact with strong oxidants and humid air. It is flammable and will burn when exposed to high heat or open flame and release toxic gases.
2.This product is toxic. Toxic and irritating if inhaled. Vapors can form explosive mixtures with air. There is a danger of burning when exposed to high heat, open flames, or oxidants.
Storage method
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The storage temperature should not exceed 30℃. The packaging must be sealed and protected from moisture. They should be stored separately from oxidants, food chemicals, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials. 2. Packed in glass bottles with wooden boxes lined with padding or galvanized iron drums. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Store and transport separately from oxidants and edible raw materials. Load and unload gently to prevent damage to the packaging.
