All abrasive blasting creates breathable particles of dust, which may include silica, and which 
may lead to various diseases including silicosis, a lung disease that can be fatal.
Abrasive rebound of direct blast also may injure an unprotected operator. 
Therefore, safety requires that those persons in the area of abrasive blasting always wear 
properly selected and maintained, government approved respiratory equipment and 
full protective clothing, from head to foot.
