1. Wear Proper Protective Equipment

Recommended protective equipment:

• Sandblasting helmet

• Dust mask or respirator

• Safety goggles

• Protective gloves

2. Keep Away from Moisture

Exposure to moisture may cause Brown Fused Alumina to:

• Clump together

• Clog the blasting nozzle

• Reduce media flow

Store in a cool, dry place and keep the abrasive media dry.
