Packaging and storage:

The product should be stored in a cool, dry, ventilated place, in the shade of the 200kg/, which is a waterproof, fireproof and heat release. Sealed storage, is strictly prohibited and oxidant, acid, alkali type mix. According to the transport of dangerous goods, to avoid the sun and rain. When carrying light light discharge, to prevent damage to packaging and containers.

Stability: specify the use and storage conditions (closed containers), stability.

Materials to avoid: water, alkali, oxidant, Potassium Permanganate, lead oxide, copper oxide or silver oxide. When there is water, corrosion of many metals. Hydrogen chloride in the reaction with water. In Potassium Permanganate, lead oxide, copper oxide or silver oxide reactions in the presence of danger of fire and explosion).

To avoid contact with the conditions: non compatible material, various heat source and flame, electrostatic discharge, wet air and water.

Decomposition products: when heated, poisonous and corrosive substances will decompose the smoke containing hydrogen chloride, phosgene and chlorine compounds. With the water reacts to produce hydrogen chloride. When exposed to alkali will be decomposed to produce flammable and explosive hydrogen.

Aggregate risk: NO
