19 Οκτ 2000 · The final report of a study on health risks posed by exposure to crystalline silica in latex paint concludes that such exposure appears to present “no demonstrable lifetime carcinogenic risk” to do-it-yourself or professional painters engaged in sanding or spray-painting activities.
It is used as a filler for paints, plastics, and rubber, whilst silica sand is used in water filtration and agriculture. Crystalline silica is irreplaceable in a series of high-tech applications, for example precision casting, fibre-optic cables, and the raw materials for computer chips.
For all practical purposes, therefore, the requirements of the HCS to provide an appropriate warning label, apply to products containing greater than 0.1 percent crystalline silica or total quartz by weight or volume, as determined by analysis of a bulk sample of the original product.
Respirable crystalline silica may present a health hazard if workers are not properly protected and workplaces are not properly controlled to reduce silica dust. Inadequate processing of the material or without the pertinent protective measures, may cause a number of diseases known as pneumoconiosis (among which silicosis is highlighted), or ...
Cutting stone, as pictured, generates dangerous crystalline silica dust that can become trapped in lung tissue and cause silicosis. This Hazard Alert focuses on countertop industry worker exposures to airborne silica dust, including from quartz in stone.
The new rule requires that employers use engineering controls − such as ventilation and wet methods for cutting and sawing crystalline silica-containing materials − to reduce workers' exposure to silica dust.
The classification of Crystalline Silica (fine fraction) as STOT RE 1 is accompanied by a series of key measures to bring about actual improvements in the current workplace situation, among them the reinforcement of the existing Social Dialogue Agreement on Workers
