Dust & Respirable Silica Monitoring & Analysis
Dust containing respirable crystalline silica is generated from the crushing of rock containing crystalline silica and the dry cutting of concrete and engineered stone products.
Possible sources of respirable crystalline silica can be from the mining and quarrying of rock, including quartzite, granite, slate and even limestone, where quartz seams are found.
HSE Australia conducts air monitoring (silica exposure monitoring) and silica dust testing to measure personal and positional exposure to respirable dust. Samples are analysed for quartz and cristobalite content to establish the presence of respirable crystalline quartz, which determines the level of risk it poses to a person’s health and dictates the controls required to reduce exposure.
Because there is no effective treatment for silicosis, controlling exposure to respirable crystalline silica dust is critical. Using engineering controls to limit exposure, in conjunction with the use of correctly fitted respiratory protective equipment, can prevent the inhalation of respirable dust and reduce the risk of silicosis.
Dust Monitoring - Personal & Stationary Monitoring
In industries such as construction, manufacturing, quarrying or mining respirable dust and respirable silica can be present from the cutting and grinding of stone, concrete, brickwork or tiles.
It is important to be aware of the health risks associated with this dust and to develop and implement control measures to protect workers from exposure.
Dust monitoring helps to identify high-dust areas and ensures that workers are not exposed to dust levels that exceed the exposure limit.
There are several ways to monitor dust levels in the workplace, including:
Stationary Dust Monitoring – this involves collecting air samples at a predefined location for a certain amount of time, then sending it to a laboratory for analysis. This can be used to measure the level of respirable crystalline silica in the air e.g., at a workshop or factory.
Personal Dust Monitoring – this involves the worker wearing an air sampling device that draws an air sample while the worker is conducting his work. Samples are then analysed in a specialised laboratory.
When choosing a method of dust monitoring, it is important to consider the set-up of the workplace, the kind of material that is processed, existing control measures and the duration of potential exposure for workers.
