Health Risks of Marble Dust. Marble is a metamorphic limestone that is widely used in the sculpturing of statues and the construction of buildings and monuments. It is commonly used in tiles, countertops and indoor flooring. Working with these materials generates marble dust, which can cause respiratory issues and irritation of the eyes and skin.

Consequently, screened product is then the transported using large amounts of heavy machinery creating movement of traffic, which causes erosion and dust bloom clouds which is ...
ادامه مطلبDust is produced in the quarrying process while it is being blasted, crushed, screened, transported and stored. There are three ways that you can manage dust: 1. Contain it, 2. collect it, or. 3. suppress it. The Pareto principle (or 80-20 rule) applies to quarry dust generation. "Eighty percent of the dust in a given quarry is generated by 20% ...

Air pollution due to quarry dust is very high during the dry season as PM 10 concentration was highest in January. Dust suppression measures must, therefore, be effectively implemented during the dry season.
ادامه مطلبControlling dust. The potential for mine and quarry workers to be exposed to harmful levels of respirable dust particles should be managed using the hierarchy of controls (shown on page 12). The higher order controls (elimination, substitution and isolation of the hazard) are the more reliable and effective means of treating the hazard.
