If you have ever been asked to report an accident at work and wondered, what is a RIDDOR, you are not alone. It is one of those terms that appears in health and safety training, risk assessments, and workplace policies, yet many people are not fully clear on what it actually means or when it applies. Getting it right matters because RIDDOR reporting is a legal duty in certain situations, not just an internal admin task.
RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. It is a UK law that requires certain workplace incidents to be formally reported to the relevant authority. In most cases, that authority is the Health and Safety Executive, although some sectors may report through local authority arrangements. The purpose is simple: serious incidents need to be recorded so patterns can be identified, risks can be reduced, and future harm can be prevented.
What is a RIDDOR in simple terms?
In everyday language, a RIDDOR report is an official notification that something serious has happened in connection with work. That might be a major injury, a work-related disease, a dangerous near miss, or even a death. Not every cut finger, minor bump, or ordinary sickness absence falls under RIDDOR. The law is focused on more serious cases.
This is where people often get confused. A workplace may have its own accident book, incident log, or internal reporting form. Those records are important, but they are not the same as a RIDDOR report. Internal reporting helps an employer track problems inside the business. RIDDOR is about reporting specific legally defined incidents to the enforcing authority.
Why RIDDOR matters
RIDDOR is not just paperwork for compliance teams. It plays a practical role in workplace safety. When serious incidents are reported properly, regulators can spot trends across industries, investigate where needed, and issue guidance or enforcement action. For employers, it also creates a clearer picture of what is going wrong and where training, supervision, or equipment may be falling short.
For workers, understanding RIDDOR can be empowering. If you work in construction, health and social care, education, catering, warehousing, or another compliance-heavy sector, it helps to know the difference between a minor incident and one that carries a legal reporting duty. That knowledge supports safer decisions and stronger professional awareness.
Which incidents must be reported under RIDDOR?
The law sets out categories of reportable incidents. The main ones are work-related deaths, specified injuries, over-seven-day injuries, occupational diseases, dangerous occurrences, and incidents involving members of the public.
A death must be reported if it results from a work-related accident. Specified injuries are serious injuries to workers, such as fractures other than to fingers, thumbs and toes, amputations, serious burns, crush injuries affecting internal organs, loss of consciousness caused by head injury or asphyxia, and injuries leading to resuscitation or hospital admission for more than 24 hours.
An over-seven-day injury is one where a worker is unable to carry out their normal duties for more than seven consecutive days after the accident. This must be work-related and excludes the day of the accident itself. This category catches incidents that may not look dramatic at first but still have a significant effect on someone’s ability to work.
Occupational diseases can also be reportable when a doctor has made a diagnosis and the disease is linked to work exposure. Examples include certain cases of carpal tunnel syndrome, severe cramp of the hand or forearm, occupational dermatitis, occupational asthma, tendonitis, and hand-arm vibration syndrome. In sectors with repeated physical tasks or hazardous exposure, this area is especially relevant.
Dangerous occurrences are specific near-miss events that did not necessarily cause injury but had clear potential to do so. These can include equipment failure, electrical short circuits causing fire, lifting equipment incidents, accidental releases of harmful substances, or structural collapse. In construction, manufacturing, and engineering settings, dangerous occurrences are a major part of RIDDOR awareness.
Members of the public may also be covered. If someone who is not at work is injured because of a work-related incident and is taken directly to hospital for treatment, that may need to be reported.
What does not count as a RIDDOR report?
This is where the detail matters. Not every accident at work is reportable. If someone trips over their own shoelaces in the office and suffers a very minor injury, it may still need to be recorded internally, but it would not normally be a RIDDOR matter unless it met the legal threshold and was work-related in the required sense.
Likewise, illnesses that are not caused or made worse by work usually do not fall under RIDDOR. A common cold, flu, or a non-work-related back problem would not usually be reportable. The same applies to minor injuries that do not fit the categories set by the regulations.
The key questions are whether the incident was work-related and whether it fits a reportable category. Both parts matter. A serious injury outside work is not reportable under RIDDOR. A workplace incident that is too minor for the legal threshold is also not reportable, even if it should still be recorded internally.
Who is responsible for reporting?
Usually, the duty sits with the employer, the person in control of the work premises, or the self-employed person. In some situations, the responsible person may be a manager, site controller, or another duty holder with health and safety responsibility.
Employees do not normally submit RIDDOR reports themselves unless they are the responsible person in a self-employed role. However, workers should report incidents internally as soon as possible so the organisation can assess whether formal reporting is required. In practice, this means staff need to know their workplace reporting procedure and managers need enough training to recognise reportable events.
This is one reason health and safety learning is so valuable. Knowing when an issue crosses from internal record-keeping into legal reporting can prevent delays, under-reporting, and avoidable compliance problems.
When must a RIDDOR report be made?
Timing depends on the incident. Fatalities and major incidents should be reported without delay. Other reportable injuries or occurrences must be reported within the time period required by the regulations. Over-seven-day injuries, for example, should be reported within 15 days of the accident.
The timing point matters because late reporting can create regulatory issues and may suggest weak internal systems. Good workplaces do not wait until paperwork piles up. They make reporting part of a wider safety process that includes immediate response, investigation, record-keeping, and action to reduce repeat incidents.
How is a RIDDOR report made?
Reports are generally submitted through the official reporting system used by the enforcing authority. The responsible person provides details about what happened, who was affected, when it happened, and why it is considered reportable.
Accuracy matters more than dramatic language. A useful report is factual, clear, and complete. It should reflect the actual circumstances rather than assumptions or blame. The report itself is only one part of the response. A proper follow-up may include reviewing risk assessments, checking training records, inspecting equipment, and identifying whether supervision or procedures need to change.
Common misunderstandings about RIDDOR
One of the biggest misconceptions is that RIDDOR is the same as an accident book entry. It is not. Another common mistake is assuming every injury at work must be reported externally. Again, that is not true. Only incidents that meet the legal criteria need a RIDDOR report.
There is also confusion around near misses. Some near misses are not reportable, but some dangerous occurrences are, even if no one was injured. That distinction is especially important in higher-risk workplaces.
A further issue is thinking RIDDOR only applies to obvious physical injuries. In fact, some diagnosed occupational diseases are covered too. If your work involves repeated movement, exposure to vibration, hazardous substances, or respiratory irritants, disease reporting may be just as relevant as accident reporting.
Why this matters for training and career development
If you are building skills for work in health and safety, care, education, catering, facilities, construction, or management, understanding RIDDOR is more than a box-ticking exercise. Employers value people who recognise legal duties, follow reporting procedures properly, and contribute to safer working environments.
For career changers and busy professionals, short online training can make these responsibilities far easier to understand. A clear course helps you move beyond memorising definitions and into practical judgement – what counts, what does not, and what to do next. That is often the difference between vague awareness and real workplace confidence.
At Skill Touch, this kind of learning fits around real life. Flexible online study gives you space to build recognised knowledge at your own pace, whether you are meeting a compliance need or strengthening your CV for the next opportunity.
The bottom line on what a RIDDOR is
A RIDDOR is not just a health and safety term you need to remember for a course or policy document. It is a legal reporting framework for serious work-related injuries, diseases, deaths, and dangerous occurrences. Knowing when it applies helps employers stay compliant, helps workers understand their responsibilities, and supports safer workplaces across every sector.
If you can tell the difference between an internal incident record and a reportable event, you are already in a stronger position than many people in the workplace. That kind of practical knowledge has real value – especially in roles where safety, duty of care, and compliance are part of everyday work.
