TEXT VERSION OF SLIDE:
Title: Amorphous Silica + Heat Forms Crystals
Type: Text and Picture Slide
Content: Includes photo of stacked bags of amorphous silica.
Speaker Notes: Another type of silica which has the same chemical formula as
crystalline silica is called amorphous silica. Amorphous silica is not
crystalline in nature and does not cause silicosis, although it may be
associated with other kinds of lung problems. However, where sufficient heat
and/or pressure is applied to amorphous silica, as in calcining or mining,
crystals may be formed. This is one way in which workers may unknowingly be
exposed to crystalline silica.
