Dust control is a critical focus of environmental management in industries where airborne dust poses a hazard. It involves using a variety of methods and technologies to reduce emissions and eliminate dust, so that the air is improved in quality and keeps people healthy at work or living nearby. With effective dust control of this kind, it is possible to prevent soil erosion and metal wear, thereby keeping both health and appearance levels high. Methods used for dust suppression include the spraying of water or chemicals on areas subject to dust formation; wind shields and screens that are set up, often fairly close together; and planting trees or bushes as a buffer between the site of work where people are breathing those dusty mists coming off freshly paved roads or playing fields on hot summer days and surrounding environment. These measures not only improve safety or sustainability--they also add to the overall productivity of industrial operations by reducing those stoppages and interruptions caused entirely by nuisance dust.
