Mineral: Silica sand can be used as a type of mineral abrasive. It tends to break up quickly, creating large quantities of dust, exposing the operator to the potential development of silicosis, a debilitating lung disease. To counter this hazard, silica sand for blasting is often coated with resins to control the dust.

for sand blasting without full respiratory protection. The federal laws that apply are 29CFR 1910. 94, 29CFR 1910. 134 and 29CFR 1910. 1000. It is recommended that users of the blast sand use OSHA-approved, positive pressure, air-fed breathing hood respirators. The positive air pressure will prevent silica dust from being drawn into the respirator.
Crystalline silica is a mineral commonly found in sand, stone, rock, concrete, brick, block or mortar. Workers are exposed to crystalline silica dust in many daily operations like cutting, sawing, drilling or crushing components that contain crystalline silica.
