Technology & offices
The activity codes this sector covers, how they split across hazard classes, the SGK work accident figures, and the Optifora modules that carry the work.
What this view covers
Information technology, communication, finance, real estate and office-based professional and administrative activities. Most codes in this view are in the least hazardous class.
A sector view is not a partition: the same NACE code can appear in more than one sector, and sector figures are not added to one another.

Legal basis — Türkiye
| Obligation | Legal basis | How the page covers it |
|---|---|---|
| Workplace hazard classes are determined by a communiqué issued by the Ministry in line with the opinion of a commission chaired by the Director General of Occupational Health and Safety, taking account of the short-term insurance premium tariff. | Occupational Health and Safety Law No. 6331, Art. 9(1) | The hazard class column of the activity code table on the Technology and office page. |
| In determining the workplace hazard class the main activity carried on in that workplace is taken into account. | Occupational Health and Safety Law No. 6331, Art. 9(2) | The NACE code and activity columns of the table; a single row is picked for a workplace. |
| The hazard classes in which workplaces fall are set out in the Workplace Hazard Classes List in Annex 1 of the communiqué. | Communiqué on Workplace Hazard Classes, Art. 1 | The source line under the table naming Annex 1 of the communiqué; the page shows every code in that annex belonging to this sector without trimming. |
| Where there is doubt about the main activity, the purpose for which the workplace was established is considered; where more than one activity fits the definition, the one with the higher hazard class prevails. | Communiqué on Workplace Hazard Classes, Art. 2(1) and 2(3) | The low-hazard, hazardous and very hazardous filter above the table; a sector may hold more than one class. |
| Where the decision changes the hazard class, employers must carry out the work required by the new class within 90 days and notify the Directorate General of Occupational Health and Safety. | Communiqué on Workplace Hazard Classes, Art. 3(4) | The free tools block of the page; the duration calculator, the emergency team calculator and the penalty calculator all take the hazard class as an input. |
The list of activity codes and hazard classes on this page comes from Annex 1 of the Communiqué on Workplace Hazard Classes, which rests on Article 9 of Law No. 6331.
