The requirement
Article 6(1)(a) of Law No. 6331 lists assigning other health personnel in very hazardous workplaces with ten or more employees among the employer's duties.
The exemption
The third paragraph of the same article is explicit: where a full-time workplace physician is assigned, assigning other health personnel is not compulsory. The exemption applies only where the physician is full time.
What they do
They support the running of health surveillance: setting up the examination schedule, keeping records, contributing to first-aid arrangements and handling health data properly. They do not stand in for the physician and cannot take over the physician's assessment.
In Optifora
The personnel side keeps the assignment together with the certificate; it warns when the requirement arises and shows the exemption where a full-time physician is assigned.
