at any time during the previous 12 months indicated a blood lead level at or above

airborne concentrations of lead are at or above the action level.  
(c) As soon as possible after notification by an employee that the employee has  
developed signs or symptoms commonly associated with lead intoxication, that the  
employee desires medical advice concerning the effects of current or past exposure to  
lead on the employee’s ability to procreate a healthy child, or that the employee has  
demonstrated difficulty in breathing either during a respirator fitting test or during use of  
a respirator.  
(d) As medically appropriate for an employee who is either removed from exposure  
to lead due to a risk of sustaining material impairment to health or who is otherwise  
limited pursuant to a final medical determination.

Rule 43. (1) An employer shall remove an employee from work who has an  
exposure to lead at or above the action level on each occasion that a periodic blood  
sampling test and a follow-up blood sampling test conducted under these rules indicate  
that the employee’s blood lead level is at or above 30 µg/dL of whole blood.  
(2) An employer shall remove an employee from work if the employee has an  
exposure to lead at or above the action level on each occasion that the average of the last  
3 blood sampling tests conducted under these rules, or the average of all blood sampling  
tests conducted over the previous 6 months, whichever is longer, indicates that the  
employee‘s blood lead level is at or above 20 µg/dL of whole blood. However, an  
employee shall not be removed if the last blood sampling test indicates a blood lead level  
below 15 µg/dL of whole blood.

R 325.51945 Return of employee to former job status.  
Rule 45. (1) An employer shall return an employee to his or her former job status  
under any of the following circumstances:  
(a) For an employee removed due to a blood lead level at or above 30 µg/dL of  
whole blood or due to an average blood lead level at or above 20 µg/dL of blood, when 2  
consecutive blood sampling tests indicate that the employee’s blood lead level is below  
15 µg/dL of whole blood.  
(b) For an employee removed due to a final medical determination, when a  
subsequent final medical determination results in a medical finding, determination or  
opinion that the employee no longer has a detected medical condition which places the  
employee at an increased risk of material impairment to health from exposure to lead.  
(2) For purposes of this rule, the requirement that an employer return an employee to  
his or her former job status is not intended to expand upon or restrict any rights an  
employee has or would have had, absent temporary medical removal, to a specific job  
classification or position under the terms of a collective bargaining agreement.
