What is Crystalline Silica?

Crystalline silica is found in minerals such as sand, soil and granite. The most common form is Quartz however there are also 2 other forms - Cristobalite and tridymite.

Where is it Found?

All three forms of Silica may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica. They are prevalent in construction sites when concrete is being drilled or cut. Also in mining, excavation and in manufacturing of electrical components.

Why is it Dangerous?

It has been classified as a human lung carcinogen. It can also cause silicosis which has proven to be fatal or disabling. At this time, there is no cure for silicosis. Sources of contamination can be

  • Construction (stone, bricks etc)
  • Bricks and Tile Cutting
  • Activity such as: mining, quarrying, masonry, roading
  • Masonry
  • Concrete Dust

How We can Help

We can provide testing services to indicate whether the work environment is safe. We can recommend a list of control methods which may assist in controlling silica levels as well as provide silica cleaning and HEPA air scrubber for filtering air.
