Silica Process

A silica process is a process, such as a work activity under particular conditions, that results in a hazardous level of RCS dust.

The work activity alone does not define a silica process. There are factors that can impact the release of RCS dust in concentrations likely to exceed the acceptable level. These factors include (but are not limited to) mine and project details, work area characteristics, weather, and the duration of the work activity.
