a female employee who is capable of procreation and who carries out work that exposes her to lead, is removed from such work when her blood lead concentration exceeds 40 g/100 mℓ or her urinary lead concentration exceeds 75 g/ℓ, or if she falls pregnant
the employee is not permitted to return to work that will expose her to lead unless her blood lead concentration is less than 30 g/100 mℓ or her urinary lead concentration is less than 65 g/ℓ, or, where the removal was due to pregnancy, the employee is no longer pregnant
the occupational medicine practitioner, if he or she deems it necessary, may certify an employee who has a blood lead concentration of less than 60 g/100 mℓ to be unfit for work in an area in which he or she is exposed to lead
Record keeping
keep all records of assessments and air monitoring for a minimum period of 40 years
keep all medical surveillance records for a minimum period of 40 years and if he, she or it ceases activities, hand over or forward by registered post all those records to the relevant provincial director
