Before application of paints and surface treatment of steel Technical requirements for non-metallic blast - cleaning abrasives Part 11. Special steel slag sand Warning. For the surface treatment used equipment, materials and abrasive, if not careful, may be hazardous. Many countries in the use of During or after use (waste management) that the presence of hazardous materials and abrasives such as. free silicon, carcinogenic or toxic substances, provisions are made. Therefore, compliance with these requirements. It is important to ensure that appropriate guidance be given and all precautions required to be implemented.
