Working with ground quartz in the countertop manufacturing industry can also expose workers to dangerous silica dust.


Exposure Control Plan for Cutting, Grinding, and Polishing
The cutting, grinding, and polishing of stone (e.g., granite) without proper dust controls can generate high levels of silica-containing dust. Breathing in this fine dust can cause a serious lung disease called silicosis. This document will help employers develop an exposure control plan (ECP) for work involving the cutting, grinding, and

Crystalline silica and silicosis Safe Work Australia
Crystalline silica is found in sand, stone, concrete and mortar. When workers cut, crush, drill, polish, saw or grind products containing silica, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis.

Preventing exposure to silica from engineered stone benchtops
Health monitoring of these workers has returned multiple positive diagnoses of silicosis. Contributing factors. Example of silica dust . Fabricating and installing natural and artificial stone bench tops can release high levels of RCS through cutting, grinding and polishing processes, particularly when dry cutting methods are used. Workers can


Artificial stone dust-induced functional and inflammatory
17/03/2016· Artificial stone produces high concentrations of silica dust. Exposure to crystalline silica may cause silicosis, an irreversible lung disease. Our aim was to screen exposed workers by quantitative biometric monitoring of functional and inflammatory parameters. 68 exposed artificial stone workers were compared to 48 nonexposed individuals


Frequently asked questions
What has been the nature of their exposure? Cutting, grinding and polishing of artificial stone exposes workers to very fine ‘respirable’ silica dust. Unlike natural stone such as granite, which typically contains only up to 30 per cent silica, artificial stone can have silica concentrations of over 90 per cent. How can these workers be


Uncontrolled dry cutting of engineered stone banned WorkSafe
A ban on the uncontrolled dry cutting of engineered stone has come into effect across Victoria to better protect workers from exposure to deadly silica dust. News article published. Wednesday 21 Aug 2019 . Industries and topics. Construction Manufacturing Crystalline silica Share this page. Print this page. Occupational health and safety regulations now prohibit the cutting, grinding and


a fine dust. OF WORKPLACE DUST EXPOSURE
manage the risks to your workers’ health and safety to reduce their exposure to silica dust: • where possible, cutting, grinding, sanding and polishing should be done wet • ventilation and filtration systems should be used to collect silica dust at its source • personal protective equipment should be used as a last resort. Face alone


OCCUPATIONAL EXPOSURES DURING IRON AND STEEL FOUNDING

Pneumoconiosis Wikipedia
Pneumoconiosis is the general term for a class of interstitial lung diseases where inhalation of dust has caused interstitial fibrosis.Pneumoconiosis often causes restrictive impairment, although diagnosable pneumoconiosis can occur without measurable impairment of lung function. Depending on extent and severity, it may cause death within months or years, or it may never produce symptoms.
