Silica Exposure
Silica is a naturally occurring substance that is found in many different rocks and minerals. It is also used in a variety of products, including concrete, bricks, ceramics, and glass. When silica is released into the air as small particles, it can be harmful to human health. This type of exposure is known as silica dust exposure.
Silica dust can cause a number of health problems, including:
- Chronic obstructive pulmonary disease (COPD): A group of lung diseases that includes emphysema and chronic bronchitis.
- Acute silicosis: A serious lung disease that can develop after a single, high-level exposure to silica dust.
- Chronic silicosis: A lung disease that develops after repeated exposure to silica dust over a period of years.
- Lung cancer: A type of cancer that develops in the lungs.
Silica dust exposure can also increase the risk of other health problems, such as kidney disease and heart disease.
The risk of silica dust exposure is highest for people who work in occupations where they are exposed to silica dust, such as:
- Construction workers
- Miners
- Glaziers
- Sandblasters
- Cutting and grinding workers
If you work in an occupation where you are exposed to silica dust, it is important to take steps to protect yourself from exposure. These steps may include:
- Wear a respirator that is designed to filter out silica dust.
- Wear protective clothing, such as a dust mask or suit, to prevent silica dust from coming into contact with your skin.
- Wet down dusty surfaces before working on them to prevent dust from becoming airborne.
- Ventilate work areas to remove dust from the air.
If you are concerned that you may have been exposed to silica dust, it is important to see a doctor. The doctor can assess your health and determine if you have been exposed to silica dust.
Here are some additional tips for avoiding silica dust exposure:
- Be aware of the risks: If you work in an occupation where you are exposed to silica dust, it is important to be aware of the risks and take steps to protect yourself.
- Follow safety procedures: Always follow safety procedures when working with silica dust. This includes wearing a respirator, protective clothing, and wet down dusty surfaces.
- Get regular medical checkups: If you work in an occupation where you are exposed to silica dust, it is important to get regular medical checkups. This will help to detect any health problems early on.
- Don’t smoke: Smoking can increase the risk of developing lung disease, including silicosis. If you work in an occupation where you are exposed to silica dust, it is important to quit smoking.
By taking these steps, you can help to protect yourself from the harmful effects of silica dust exposure.
Silica Dust Exposure in Australia
Silica is a naturally occurring substance that is found in many different rocks and minerals. It is also used in a variety of products, including concrete, bricks, ceramics, and glass. When silica is released into the air as small particles, it can be harmful to human health. This type of exposure is known as silica dust exposure.
In Australia, the workplace exposure standard (WES) for respirable crystalline silica (RCS) is 0.05 mg/m3 as an eight-hour time-weighted average (TWA). This means that the average concentration of RCS in the air at a workplace should not exceed 0.05 mg/m3 over an eight-hour period.
The risk of silica dust exposure is highest for people who work in occupations where they are exposed to silica dust, such as:
- Construction workers
- Miners
- Glaziers
- Sandblasters

Silica Dust Exposure Limits in Australia
Silica is a naturally occurring substance that is found in many different rocks and minerals. It is also used in a variety of products, including concrete, bricks, ceramics, and glass. When silica is released into the air as small particles, it can be harmful to human health. This type of exposure is known as silica dust exposure.
In Australia, the workplace exposure standard (WES) for respirable crystalline silica (RCS) is 0.05 milligrams per cubic meter (mg/m3) as an eight-hour time-weighted average (TWA). This means that the average concentration of RCS in the air at a workplace should not exceed 0.05 mg/m3 over an eight-hour period.
The WES for RCS is set by the Australian Government’s Department of Health. The WES is based on the best available scientific evidence on the health risks of silica dust exposure.
The WES for RCS is lower than the previous WES of 0.1 mg/m3. The lower WES was introduced in 2019 to protect workers from the harmful effects of silica dust exposure.
There are a number of ways to reduce exposure to silica dust in the workplace. These include:
- Wetting down dusty surfaces before working on them to prevent dust from becoming airborne.
- **Using dust control measures, such as ventilation and air filtration systems.
- **Ensuring that workers wear appropriate personal protective equipment (PPE), such as respirators and protective clothing.
- **Providing workers with training on the risks of silica dust exposure and how to protect themselves.
If you are concerned that you may have been exposed to silica dust, it is important to see a doctor. The doctor can assess your health and determine if you have been exposed to silica dust.
Here are some additional tips for avoiding silica dust exposure in Australia:
