A: It must be stored in a sealed container in a cool, dry place away from light. The ambient temperature should ideally be ≤30°C, and the product must be kept away from heat sources, open flames, and oxidizing agents. Prolonged exposure to air should be avoided to prevent slight oxidation that could compromise its purity. The product has a shelf life of 24 months; once opened, it is recommended to use the entire contents within 3 months to ensure optimal performance.
A: It is classified as a Class 3 Flammable Liquid (UN No. 1993); therefore, transportation must be handled by a team certified to transport hazardous chemicals. During transit, the shipment must be protected from direct sunlight and rain, and care must be taken to prevent damage to the packaging. Strict adherence to both international and domestic regulations regarding the transport of hazardous chemicals is mandatory; PURUI provides comprehensive compliance documentation to ensure safe and smooth transportation.
