  • Crystalline Silica Safety Training | EHS

    This course will provide general crystalline silica safety information so that employees that may be using or disturbing materials containing crystalline silica can be properly prepared to minimize and prevent exposure. The following materials are included in the training. What crystalline silica is; Materials that may contain crystalline silica

    Silica is a naturally occurring material in minerals, flint and in some plants in crystalline phase. Silica commonly used in industries is in synthetic form. Surface area, pore volume, pore size and particle size are independently controllable to some extent. The crystalline silica may be classified based on atmospheric pressure as:

    Reduce crystalline silica exposure and learn about silicon dioxide hazards. The term "silica" broadly refers to the mineral compound silicon dioxide (SiO 2).Although silica can be crystalline or amorphous in form, crystalline silica is more hazardous to employees and is the focus of this document.
