Hazard Alert: Worker Exposure to Silica during Countertop

However, cutting, grinding, chipping, sanding, drilling, and polishing natural and manufactured stone products can release hazardous levels of very small, crystalline silica dust particles into the air that workers breathe. 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

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

Occupational exposures during iron and steel founding cause cancer of the lung. No data on the carcinogenicity to experimental animals of mixtures present in iron and steel founding were available to the Working Group. Occupational exposures during iron and steel founding

Respiratory symptoms and pulmonary function in mill

This study surveyed wood dust exposure levels and pulmonary hazards among wood mill workers. Dust concentrations as measured by six‐stage cascade impactors were high in work areas of grinding and screening. Total dust concentrations for these dusty activities ranged from 4.4 to 22.4 mg/m 3, and the respirable proportions were between 2.4% and

The Effect of Local Exhaust A Ventilation Controls on Dust

Ventilation Controls on Dust Exposures During Concrete Cutting and Grinding Activities This study assessed the effectiveness of commercially available local exhaust ventilation (LEV) systems for controlling respirable dust and crystalline silica exposures during concrete cutting and grinding activities. Work activities were performed by union

Effects of exposure to flour dust on respiratory symptoms

Chen divided the flour mill workers into heavy-exposure group and light-exposure group and observed that FEV1, FVC, MEF and PEF were significantly decreased in the heavy-exposed group than lightly exposed group. The findings indicated that exposure to high concentrations of dust for a long period of time impairs the pulmonary function. Yach et al.
