Silica Exposure Control Program

The Silica Exposure Control Program describes the hazards associated with silica dust, outlines the steps to ensure employees who work with or around silica are not exposed to hazardous levels of silica dust, and provides procedures to minimize exposures for common silica related work duties.

Silica exposure can come from handling sand, cutting concrete and abrasive blasting.

Before implementing any portion of this safety program or completing the training please contact the EHS Industrial Hygienist to determine which elements are applicable to you.
