RIDDOR, which stands for the Reporting of Injuries, Diseases, and Dangerous Occurrences Regulations, is a regulation in the United Kingdom that mandates employers and people in control of work premises to report and keep records of specific incidents that occur in the workplace. Deaths, major injuries, occupational diseases, and other potentially hazardous occurrences are included.

RIDDOR's primary objective is to assist in monitoring the performance of occupational health and safety measures, identifying potential hazards, and preventing incidents in the future. Consequently, it guarantees that incidents are examined and dealt with in a timely manner. Understanding RIDDOR and acting in accordance with its requirements is essential for ensuring that workplace safety and legal compliance are maintained.
