Stone dust is a by-product of crushed rocks; as a multipurpose building material it provides compact results. Despite its many benefits to the construction industry, it comes with a number of health risks.

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.
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
12/09/2019· 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.
of crystalline silica dust reported in silica mill workers, of years at the mill, type of grinding stone used, frequency of chiseling of the stone, smoking history, and history of pulmonary
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.
What isn’t a mystery is how Cameron contracted silicosis. Until recently, he was a stonemason. For 40-50 hours a week, Cameron was working with engineered stone products and inhaling the dust
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
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
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
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
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 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
Note: The information included on this page is valid as of October 2018. Clinical guidelines are currently being developed for engineered stone workers at risk of exposure to silica and the information on this page will be updated once these guidelines become available.
Using Ventilation Control Technology to Reduce Respirable Dust Exposures at U.S. Metal/Nonmetal Mining Operations Cecala A B 1, Zimmer J A 1, Colinet J F 1, Timko R J 1, Chekan G J 1, and Pollock D E 1 ABSTRACT It has long been known that ventilation is a cost-
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
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
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.
13/05/2014· Risk assessing general workplace dusts. May 13, 2014. Airborne dusts are of particular concern as they are associated with widespread occupational lung diseases. The health effects are not only caused by exposure to toxic dusts, such as asbestos, wood dust and crystalline silica, but also by exposure to general workplace dusts — poorly
The workplace exposure standard. The workplace exposure standard for respirable crystalline silica that must not be exceeded is 0.1 mg/m3 (eight-hour time weighted average). PCBUs should keep worker exposures to respirable silica dust as low as reasonably practicable. Air monitoring will need to be conducted If there is any doubt that the
Two workers were female, and all seven of the workers were Hispanic. They had worked at 12 Colorado companies dur-ing 1984–2018, most of which employed <50 workers. Five patients reported cutting, grinding, and polishing mainly engineered stone; two reported only bystander exposure to engineered stone dust during workplace housekeeping duties.
10/10/2019· OXYGEN FILES: The property market love affair with stone benchtops for bathrooms and kitchens is proving deadly for hundreds of Australian workers.Silicosis rates are rising so fast that Queensland now has a shortage of stonemasons.Too many are disabled or have died due to silicosis, which is caused when microscopic particles of silica dust are inhaled during cutting and grinding of
Businesses must have a documented way of managing dust and a strict monitoring program to ensure dust exposure is kept to an acceptable level and statutory exposure standards are met. Part of this system must include monitoring to determine workers’ exposure to airborne concentration of dust
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.
