It is estimated that more than 3.2 million workers in the EU are exposed to silica dust in their professions. 16 Inhaled silica dust has been linked to silicosis, sarcoidosis, and COPD. 17–19 In certain cases, silica has also been suspected of causing lung cancer and is currently classed as a carcinogen by the IARC. 20 Silica dust …
Employers can effectively reduce exposure to silica dust by opting for safer alternatives to crystalline silica materials whenever feasible. When working with crystalline silica becomes necessary, the most efficient approach is to manage silica dust directly at its source. Water spraying is often the optimal choice for dust control.
The Managing respirable crystalline silica dust exposure in construction and manufacturing of construction elements Code of Practice 2022 (PDF, 1.71 ) sets out: enforceable standards that must be met to minimise the risk of worker exposure to RCS dust in construction work and the manufacturing of construction elements
The exposure standard for respirable crystalline silica dust is 0.05 mg/m3 as a time-weighted average (TWA) airborne concentration over 8 hours. An 8-hour TWA exposure standard is the average airborne concentration of a particular substance permitted over an 8-hour working day and 5-day working week.
An important concern is the risk of developing silicosis, a progressive and irreversible lung disease. Silica exposure can also impair lung function by causing COPD. As lung tissue turns into scar tissue with silicosis, reduced lung function occurs and gets progressively worse, even after dust exposure has ended.
Most people get silicosis from a workplace where they inhale large amounts of silica dust. Learn more about the causes, risk factors, symptoms, treatments, and …

(fracking), is also a source of respirable crystalline silica exposure. About 2.3 million people in the U.S. are exposed to silica at work.
Silicosis may develop in three ways. They are: 1. Chronic silicosis: This usually happens when you've been exposed to breathable dust for more than 10 years. The amount of silica in the dust is also a factor. There are these forms of chronic silicosis: simple silicosis and progressive massive …
Addressing a problem first identified 50 years ago, federal regulators say stricter new rules to limit miners' exposure to silica dust are expected to finally go on the books on Tuesday.
Some of this dust may be fine enough to breathe deeply into the lungs and may be associated with negative health effects, especially for workers with repeated exposure over time to high levels of this type of dust. The fine dust can include respirable crystalline silica (RCS), which is often too fine to see with normal lighting.
Any level of silica exposure can result in silicosis. There are three types of silicosis: Acute silicosis forms a few weeks or months after high levels of silica exposure. This condition progresses rapidly. Accelerated silicosis comes on five to 10 years after exposure. Chronic silicosis occurs 10 years or more after silica exposure.
10| KNOW Workplace Cancer Workers Toolbox Talk Silica What is a 'Workplace Exposure Standard'? • The maximum allowable concentration in workplace air • In Australia the standard is 0.1mg/m3 over an eight-hour day • This is currently under review - a reduced standard of 0.05g/m3 has been recommended by work health and safety regulators ...

In some workplaces, using machinery and products with a high silica content can dramatically increase the risk of exposure to silica dust. Workers' exposure to silica dust can pose various health risks, such as: 1) Acute Silicosis. Exposure to high levels of silica dust can lead to acute silicosis within weeks or years.
Occupational and environmental exposure to silica dust is a known risk in several common occupations. According to the U.S. Department of Labor, approximately 2.3 million people face regular workplace exposure to the mineral. Employers must take steps to reduce silica dust exposure.
