The leaflet explains what crystalline silica is, in what workplaces it is found, how workers can be exposed, what health effects might occur and how to prevent risks at workplaces.
small crystalline silica particles are at risk for silicosis – an incurable, progressively disabling disease which may be fatal and other severe health damages. According to the USA OSHA alert of February 2015, workers exposed to airborne crystalline silica
Crystalline silica is the scientific name for a group of minerals composed of silicon and oxygen. The term crystalline refers to the fact that the oxygen and silicon atoms are arranged in a three- dimensional repeating pattern.
The fine dust is called respirable crystalline silica (RCS) and is too fine to see with normal lighting. The leaflet explains how RCS can damage health and what to do to prevent harm. Related...
In everyday contexts, crystalline silica is safe. However, in industrial workplaces, where materials containing crystalline silica are crushed, ground, drilled, or used in similar processes, a very fine dust is produced. This is known as Respirable Crystalline Silica or RCS. When high levels of
It identifies 18 common construction tasks that generate high exposures to respirable crystalline silica and for each task, specifies engineering controls, work practices, and respiratory protection that effectively protect workers.
Under the HCS, appropriate hazard warning labels are required for materials containing more than 0.1 percent crystalline silica by weight or volume which have anticipated downstream uses where crystalline silica may become airborne and present an inhalation hazard to employees working with that mater ial.
