The use of an abrasive granular material, such as sea sand, blown under very high pressure over a surface, such as the rough stone fabric of a building, in order to clean, polish, or smooth it. Sandblasting exposes workers to a high risk of pneumoconiosis, especially silicosis, and the high-intensity noise is harmful to hearing. Since these dangers have been appreciated and worker safety laws enforced, sandblasters wear both respirators and ear protectors. Water-based sandblasting considerably reduces exposure to hazardous inhalable particles.
