Handling and Storage

Caustic soda is corrosive. It should be stored away from oxidizing agents and acidic materials in a cool, dry, ventilated place. Although stable under normal conditions, caustic soda reacts with metals to form explosive and flammable hydrogen gas. Adding water to caustic soda produces a violent, exothermic reaction.

When fighting caustic spills, proper protective clothing and respiratory equipment should be used and unprotected personnel should be moved upwind of the area. Large spills must be reported to the QVC Emergency No. 4476 5800. Disposal of spill material should be in accordance with Qatari regulations.

Kindly refer to the QVC Material Safety Data Sheet (MSDS) for more detailed information regarding the use, storage and safe handling of this product.
