Reg. 16286OSHA issued a new final rulemaking to reduce silica dust exposure that will directly affect more than 2 million construction workers who drillcutcrushor grind silica-containing materials such as concrete and stoneand 300,000 workers in general industry operations such as brick manufacturingfoundriesand hydraulic fracturing.
Identifying the hazard of silica dust Safe Work Australia. Manufacturing stone items can result in a risk of dust exposure. Fabricating installing maintaining and removing silica containing products Silica dust can be made when cutting grinding trimming removing or blasting silica containing products or from storing or disposing of dusty waste from these processes.
Silicosis is a disease caused by silicon poisoning -- a common side-effect of working in stone-crushing yards. The workers breathe in the silica dust while working in the yardsand the silicon

Compliance and Safety for Silica. If you work in a profession that involves crushing asphaltconcrete or rocks (e.g. miningmilling or construction)youre probably aware of OSHAs tightening Permissible Exposure Limit (PEL) for respirable crystalline silica (Table 1 of OSHA Standard 29 CFR 1926.1153).The new standard 50 micrograms per cubic meter with an active level of 25
due to exposure of silica dust. Stone crusher impact zones are covered with GraniteSilica sand and Morrum. The various crushing operations involved in stone crushing e.g. blastingmanual cuttingcrushing and transportation emit fugitive stone dust. These fine aerosol of stone dust causes health problems among the stone crusher workers.
Silica dust is created when a material containing crystalline silica is subjected to a mechanical process such as crushinggrindingdrillingcuttingcrushing or polishing. The respirable crystalline silica released is 100 times smaller than a grain of sandmeaning it may be inhaled unknowingly and can penetrate deep into the lungs.
