Before demolition or refurbishment, the person with management or control reviews the asbestos register and revises it if inadequate for the proposed work (for example an inaccessible area likely to contain asbestos that will become accessible) and gives a copy to the PCBU carrying out the work before it starts; that PCBU obtains a copy before starting.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
