Silica is found in many resources used in construction. In and of itself, that is not a problem, until you wish to drill, mill, saw, grind or cut: activities that occur regularly in construction work.

These activities release fine silica dust particles, which can penetrate deep into the lungs where, years later, they can cause irreparable damage. In the toolbox film The Dangers of Silica Dust, presenter Lottie Hellingman talks about the dangers of exposure to silica dust and the measures employers and employees can and must take to protect themselves from exposure.
