Handling and storageHandle to minimize dust generation. When transferring into containers in the presence of flammable liquids, gases or dust, electrically ground both containers to prevent static sparks and risk of explosion. Store in a cool, dry warehouse: shelf life approximately 4 years in drums and 12 months in big bags (from production date). Do not store big bags outdoors for prolonged periods; protect from UV exposure and rain. Reseal opened packages to avoid contamination and moisture or vapor adsorption.
