What is Silica Dust and Where is it Found? (source: OSHA.gov) Crystalline silica is an important industrial material found abundantly in the earth's crust. Quartz, the most common form of silica, is a component of sand, stone, rock, concrete, brick, block, and mortar. Materials containing quartz are found in a wide variety of workplaces.
Silica, present in concrete dust, is a hazardous material and is the focus of the new OSHA regulation 1926.1153 Table 1. The new OSHA respirable crystalline silica dust regulation offers several options for compliance and at Hilti, we want to help you understand those options.
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.
