Silica Hazards Safety Topics SafetyInfo

Dangers of Silica Silica may be of several distinct types. For example, quartz is a crystalline form of silica and is the most common mineral in the earth's crust. When rock containing quartz is chipped, hammered, drilled, crushed, loaded, hauled, or dumped, small particles of silica are released into the air and can be inhaled by workers.

How Is Quartz Formed? Our Pastimes

Quartz can be formed naturally from the silica which collects in the earth. When silicon (Si) and oxygen (O2) combine, it will create silicon dioxide (SiO2), which is quartz. For this reason, quartz will form underground quite easily whenever a combination of oxygen and silica-rich solutions are present.
