Preventing Silicosis and Deaths From Sandblasting (92-102
2014-6-6 Abrasive blasting with sands containing crystalline silica can cause serious or fatal respiratory disease. The National Institute for Occupational Safety and Health (NIOSH) requests assistance in preventing silicosis and deaths in workers exposed to respirable crystalline silica during sandblasting.
Silica Hazards Safety Topics SafetyInfo
The silica sand used in sandblasting breaks into fine particles that stay in the air. If these particles are small enough to be inhaled deeply into the lungs, they are known as respirable crystalline silica. Inhaling these fine silica particles causes more lung damage than inhaling larger particles.
