Where the employer expects an employee removed under paragraph (a) or (b) of r 199(1A) (or of the earlier r 199(1)) to come back to lead-risk work, it must have a registered medical practitioner re-examine them at intervals the doctor sets to judge whether they are suitable to return. The employee must not go back until both conditions are met: the blood lead level is below 0.97 micromoles per litre (20 micrograms per decilitre) for men and women not of reproductive capacity, or below 0.24 micromoles per litre (5 micrograms per decilitre) for women of reproductive capacity (r 201(3A), current thresholds); and a registered medical practitioner certifies the employee fit to return. The earlier r 201(3) return levels were 1.93 and 0.48 micromoles per litre. The duties extend to independent contractors and support sections 21 and 22(1) of the Act.
