HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Use clean, dry equipment for weighing and blending to prevent moisture pickup.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust where dust may be generated during powder transfer.
Minimize airborne particulate accumulation in enclosed areas.
Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain consistent assay.
