The Hazards Of Silica Dust Crystalline silica is a common mineral in the earth's crust and is found in many types of rock including sand, quartz, and granite. Silica is present in both work and non-work environments, and exposure to crystalline silica dust has long been known to cause a disease called silicosis August 18, 2019 by Willow Aliento One of the major health hazards on many construction sites is the one you often cannot see—crystalline silica dust. The extremely fine particles are released when granites, sand, bricks, cement, and other materials release dust due to activities such as cutting, grinding and blasting The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles. These dust particles are very small. You cannot see them. This respirable silica dust causes lung disease and lung cancer . This webpage provides information and guidance for workers, employers, and safety and health professionals on ways to minimize crystalline silica exposures at work and prevent related health outcomes.

With this in mind, the severity of the diseases that one may develop as a result of exposure to silica dust, is also imperative. These diseases include silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD) While the regulation for silica dust is new, the hazards and health consequences have been known for decades. Use engineering controls and other effective safeguards to reduce the amount of this dust in the air to reduce overexposure. IF IT'S SILICAIT'S NOT JUST DUST!
About 2.3 million people in the U.S. are exposed to silica at work. Workers who inhale these very small crystalline silica particles are at increased risk of developing serious silica-related diseases, including: Silicosis, an incurable lung disease that can lead to disability and death a vacuum dust collection system to capture dust. In some operations, respirators may also be needed. Employers who follow Table 1 correctly are not required to measure workers' exposure to silica from those tasks and are not subject to the PEL. Table 1 Example: Handheld Power Saws If workers are sawing silica-containing materials When silica is present, workers may also face an increased risk of silicosis and lung cancer. Controls. A recent NIOSH Health Hazard Evaluation (HHE) found that drywall sanders were exposed to as much as 10 times the permissible exposure limit (PEL) of 15 mg/m3 for total dust set by the Occupational Safety and Health Administration (OSHA)

Dust Containing Silica 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 Why silica dust is considered to be a health hazard is a question that can be answered with a simple fact. Every year, about 1, 000 workers die in the United Kingdom because of silica exposure. In addition to this, an even greater number of people develop severely debilitating health problems because of silica exposure SILICOSIS. A far greater concern to workers and local communities is the risk of exposure to crystalline silica contained in airborne dust. The term silica is a generic reference to the mineral compound silicon dioxide (SiO2), which can be found in either amorphous or crystalline form Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. It is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs.It is a type of pneumoconiosis.

3-E Safety Services, LLC conducts training on Silica Awareness (Crystalline Silica). The class takes anywhere from 30-minutes to 1-hour, depending on the depth of the training requested. Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica The strategy for controlling the silica hazard can therefore be broken down into three basic approaches: prevent silica dust from getting into the workplace air remove silica dust present in the air; if present, prevent workers from inhaling the dust. To avoid the inhalation of silica, it is essential to have the following control methods in place
Silica dust particles enter the air when you saw, grind, drill or otherwise cause a material to shed dust. Unlike normal dust, which will likely do no more than make you sneeze or get you a little dirty, silica dust — also called respirable crystalline silica particles — can cause more serious problems Furthermore, permanent effective control of specific hazards like dust needs the right approach to management in the workplace. Chapters 1 and 2, therefore, deal with the properties of dust and how it causes disease. Chapter 3 discusses the relationship of such as those containing free crystalline silica. All materials containing silica can result in the presence of respirable silica particles when chipping, cutting, drilling or grinding Silica exposure occurs through inhalation of silica containing particles • Identify the health hazards that result from exposure to excessive silica dust over long periods of time: silicosi 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 and give off toxic substances
