HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Maintain good hygiene and clean-up practices in handling areas.
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:
