RIDDOR stands for Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. It is a UK health and safety legislation that requires employers, the self-employed, and people in control of work premises to report and keep records of work-related accidents, diseases, and dangerous occurrences, including near misses, that take place at work or in connection with work. The law was revised in 2013 to simplify the reporting requirements and to create a record of incident numbers and types in order to form a picture of the risks involved in different industries and occupations. RIDDOR applies to all responsible persons, and if employers ignore RIDDOR and fail to report incidents, they are breaking the law. However, general employees do not have a legal responsibility to report incidents under RIDDOR, but they should report any incidents they witness or experience to an appropriate supervisor. The aim of RIDDOR is to keep workplaces safe, address risks, and minimize them, and to help regulators such as the Health and Safety Executive (HSE) advise organizations on how to avoid incidents.
