| 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 and taking account of the short-term insurance premium tariff set under Article 83 of Law No. 5510. | Occupational Health and Safety Law No. 6331, Art. 9(1) | The binding-text caption at the foot of the page naming the Workplace Hazard Classes Communiqué. |
| The hazard classes in which workplaces fall for occupational health and safety purposes are set out in the Workplace Hazard Classes List in Annex 1 of the communiqué. | Communiqué on Workplace Hazard Classes, Art. 1 | The NACE code, activity and hazard class columns of the query table; the list carries every activity code together with its class. |
| The hazard class of the main activity carried on in the workplace is taken into account; where more than one activity fits the definition of a main activity, the one with the higher hazard class prevails. | Communiqué on Workplace Hazard Classes, Art. 2(1) and 2(3) | The filter under the search box: a single row is picked for a workplace and the class of that row is the result. |
| The employer shall notify a change in the main activity to the Ministry of Labour and Social Security within one month at the latest. | Communiqué on Workplace Hazard Classes, Art. 2(2) | How the query result is used: when the activity code changes the result changes too, and the deadline is one month. |
| The decision is served on the workplace; where it 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 other tools the query result feeds: the duration calculator, the emergency team calculator and the penalty calculator all take the class as an input. |
The hazard class is a Turkish institution tied to the NACE activity code: it is determined by a communiqué issued by the Ministry and the whole list sits in Annex 1 of that communiqué.
