Special electrical equipment:
 Install spark free electrical equipment.
Prevention of static electricity: Take precautionary measures against static discharges.
Quantity limits : Not Available
Type of material used in the packaging/containers:
The product is usually put on the market in cardboard octagonal containers (octabins), in big bags or bulk. It is recommended not to double stack octabins.
Other suitable containers: steel drums.
