Crystalline Silica 

Crystalline silica has been deemed “the new asbestos” due to its similar carcinogenicity and its prominent use in the Australian building and construction industry. While working with products containing the deadly substance remains legal, it is, however, a PCBU requirement to ensure that workers are not exposed to levels above todays exposure limits standards.


Silica in the Industry

Crystalline silica is found in sand, stone, concrete and mortar. It is also used to make a variety of products including composite stone, bricks, tiles and some plastics. When products containing silica are cut, crushed, drilled, polished, sawn or ground, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis.


Types of air monitoring

Air monitoring is the only way to ensure your day to day operational control measures are effective in protecting against deadly dust. All air-monitoring is performed following AS 2985-2009 Workplace atmospheres.

  1. Exposure (personal) – To assess individual exposure during works processes.

  2. Static - to assess control measures at a fix position in high-risk areas such as machinery.
