Whoever made the r 319K(1) record (employer or self-employed person) must retain it for as long as the silica process, or combination, keeps being carried out at that workplace. The record is the one describing how the r 319J(2) factors were weighed and the resulting classification, so it must stay on file for the life of the process, not just until the next review. Maximum penalty: 100 units (individual), 500 units (company).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
