Crystalline silica and silicosis | Safe Work Australia

Crystalline silica (silica) is found in sand, stone, concrete and mortar It is also used to make a variety of products including composite stone used to fabricate kitchen and bathroom benchtops, bricks, tiles and some plastics When workers cut, crush, drill, polish, saw or grind products that contain silica, dust particles are generated that are small enough to lodge deep in the lungs andcrystalline silica dust Through the 1980’s and into the 1990’s, United States Bureau of Mines (U) research program addressing silica dust sources and worker exposure had mainly focused on surface and underground coal mining and surface processing operations for the nonmetal mining industry Numerous studies were conducted which have lead to the development of improved controlNIOSH’s Pittsburgh Research Laboratory is

RESPIRABLE CRYSTALLINE SILICA: THE FACTS

Crystalline silica is a natural substance found in stone, rocks, sand and clay, as well as products like bricks, tiles, concrete and some plastic composites When these materials are worked on, for example by cutting or drilling, the crystalline silica is released as a very fine dust which can be breathed in This dust is one of the oldest workplace hazards – and it still causes hundreds ofThe fine dust is called respirable crystalline silica (RCS) and is too fine to see with normal lighting The quantity of silica contained in stone and other materials varies considerably between different types of stone: Approximate crystalline silica content of different materials Sandstone 70–90% Concrete, mortar 25–70% Tile 30–45% Granite 20–45%, typically 30% Slate 20–40% BrickControl of exposure to silica dust
