How often is a risk assessment renewed?

Question

Accepted Answer

A risk assessment is renewed at most every two years in highly hazardous workplaces, every four in hazardous ones and every six in low hazard ones. Even before that, it is renewed wholly or partly when the site moves, technology or production method changes, or a work accident, occupational disease or near miss occurs. The calendar: two, four, six years Article 12/1 of the Occupational Health and Safety Risk Assessment Regulation is clear: a risk assessment already made is renewed at most every two, four and six years in highly hazardous, hazardous and low hazard workplaces respectively. Hazard class Maximum renewal interval Highly hazardous 2 years Hazardous 4 years Low hazard 6 years Situations that force an earlier renewal The second paragraph of the same article requires the assessment to be renewed wholly or partly, having regard to whether the new risks affect the whole workplace or part of it, in these situations: The workplace moves or the buildings are altered. The technology in use or the substances and equipment change. The production method changes. A work accident, occupational disease or near miss occurs. Legislation on limit values for the working environment changes. Workplace measurements or health surveillance results make it necessary. A new hazard arises outside the workplace that may affect it. The form of the document Renewal is not restamping the old document with a new date; the assessment itself is done again. Every page of the risk assessment document is initialled by the people who carried it out, the last page is signed, and it is kept at the workplace. The document may be prepared and archived electronically, so a wet-signed paper file is not the only route. Not missing the trigger In practice it is the events in the second paragraph, rather than the calendar, that get missed. If near misses, equipment changes or the relocation of a section are not recorded, the renewal trigger is never pulled. The 2025 social security data show 766,039 work accidents under the 4a scheme; each one is a renewal ground at the workplace concerned. If it is not done Failing to carry out or commission a risk assessment starts at TRY 66,725 in the 2026 administrative fine tables, rising with workplace size and hazard class. The tables carry a further item, applied monthly while the breach continues, starting at TRY 100,119. Failing to carry out the checks, measurements, examinations and research needed to identify risks starts at TRY 33,326.
