The occupational physician may prescribe any additional examinations necessary :
1° To determine the employee’s fitness for the job and, in particular, to screen for ailments which contraindicate the employee’s suitability for the job;
2° Screening for an occupational disease or disease of an occupational nature likely to result from the employee’s work;
3° Screening for conditions likely to expose the employee’s family and friends to the risk of contagion.
To this end, the occupational physician is informed by the head of the establishment, as soon as possible, of any change of assignment and may, on this occasion, take the initiative of re-examining the employee.
