The PCBU immediately removes a worker from lead risk work if blood lead reaches or exceeds 30 micrograms per decilitre (males and females not of reproductive capacity) or 10 micrograms per decilitre (females of reproductive capacity), if the supervising practitioner recommends it, or if a control failure makes reaching those levels likely, and notifies the regulator as soon as practicable; arranges a medical examination by an experienced practitioner within 7 days (consulting the worker on the choice); and, if a return is expected, arranges monitoring at the practitioner's frequency and does not allow return until blood lead is below 20 (or 5 for females of reproductive capacity) and the practitioner is satisfied the worker is fit.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
