13/03/2011· Airborne Particulate Hazards. Free crystalline silica is the most abundant compound in the earth’s crust and, consequently, is the most common airborne dust that miners and quarry-workers face. Free silica is silicon dioxide that is not chemically bonded with any other compound as a silicate. The most common form of silica is quartz although
For individual quarry operations, as part of their risk-assessment programme under the Management of Health and Safety at Work Regulations, 1999, health risks can be assessed subjectively. In order to be able to make an assessment of the risk of health hazards, the two major elements that need to be considered are (fig. 2):
A major health risk encountered by people working in the quarrying industry is exposure to fine respirable dust which contains silica. Silica is found in the majority of rocks, sands and clays and therefore workers within the quarrying industry and masonry industry are particularly susceptible. Silica dust exposure to workers can arise from the quarrying of stone, crushing, screening and
In the light of these known hazards from gravel dust it is essential that evidence is available (perhaps from existing gravel quarries) of the extent to which PM 10 and PM 2.5 particles of crystalline silica dust can be expected to be found (say over the course of a year) at distances of say one, two and four kilometres from quarry workings
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. Respirable crystalline silica is a chemical compound present in stone dust, soil, granite and many other minerals. It has been classified as

HSE's Sector and Health priority plans; Competence in health and safety; RIDDOR; Explosives; Silica. One of the health risks from working in the quarry industry is that of exposure to fine dust containing crystalline silica (otherwise known as quartz). Quartz is found in almost all kinds of rock, sands, clays, shale and gravel. Workers exposed
pozzolana quarry dust; concentration of silica, chromium, cadmium and lead in the dust; and to assess the quarry workers awareness of the safety and the health risks in the quarry. Purposive and random sampling was used to get 110 workers for the study and dust samples were collected at 0m, 25m and 50m
This fact sheet has been prepared to explain the type of dust that is generated from mine sites and the potential risks from mine dust to health. What is particulate matter? Commonly called "dust," scientists and regulators refer to the term particulate matter (or PM) to describe the range of particles that exists in the air we breathe.
26/06/2018· Making mining and quarry work safer. Our tools and guides can be used to assess and control the specific risks in mining and quarries. Consult. Involving your employees in health and safety issues can result in a safer workplace. That's why consultation is an important part of risk management.

But if the amount of dust is large, the macrophage system may fail. Dust particles and dust-containing macrophages collect in the lung tissues, causing injury to the lungs. The amount of dust and the kinds of particles involved influence how serious the lung injury will be. For example, after the macrophages swallow silica particles, they die

Along with the TUC, it is calling for a review of dust exposure levels, in line with recommendations from the trade union side of the Health and Safety Executive’s (HSE) Advisory Committee on Toxic Substances (ACTS). Unions also want a high profile campaign to inform workers of the risks posed by dust
The purpose of this study is to assess the effects of quarry dust among workers of quarry industry, their level of awareness and knowledge of the kinds of the health hazards or injuries they are exposed to on the job and to proffer recommendations on how to increase their awareness and compliance with the use of safety protective devices
Health effects of dust What is dust? Dust is a common air pollutant generated by many different sources and activities. Terms explained. Pollutant a substance that has been introduced to the environment and has undesired or negative effects.
