Most people only ask what is RIDDOR when something has already gone wrong at work. That is exactly why it matters. If you work in health and social care, construction, education, hospitality, warehousing, or any other regulated setting, knowing when an incident becomes legally reportable is part of keeping people safe and staying compliant.
RIDDOR is one of those terms that appears in workplace safety training, accident books, and policy documents, but it is often misunderstood. Some people assume every accident must be reported under RIDDOR. Others think it only applies to major injuries on construction sites. In reality, it is more specific than that, and getting it wrong can lead to missed legal duties, poor record-keeping, and avoidable risk.
What is RIDDOR?
RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013. It is a UK law that requires certain work-related incidents to be formally reported to the relevant enforcing authority.
In simple terms, RIDDOR is about notifying the authorities when serious workplace injuries, occupational diseases, deaths, or near-miss events happen. It helps regulators identify patterns, investigate serious failings, and improve health and safety standards across industries.
It does not mean every cut, bruise, or minor accident is reportable. Many incidents should still be recorded internally, but only certain types meet the threshold for a RIDDOR report.
Why RIDDOR matters in everyday workplaces
RIDDOR is not just a legal formality. It gives employers and responsible persons a structured way to flag serious incidents and act on them. If a member of staff develops a work-related disease, a resident in a care setting suffers a reportable injury, or unsafe equipment causes a dangerous occurrence, reporting creates accountability.
For learners and employers alike, understanding RIDDOR supports more than compliance. It strengthens workplace culture. Teams that know what must be reported are better placed to respond quickly, investigate properly, and reduce the chance of the same thing happening again.
This is especially relevant in sectors where health and safety responsibilities form part of day-to-day work. In care, education, food handling, facilities, and construction, staff are often expected to recognise hazards, follow reporting procedures, and maintain accurate records.
What incidents must be reported under RIDDOR?
The key point is that the incident must usually be work-related and fall into a reportable category. The main categories include deaths, specified injuries, injuries leading to over-seven-day absence, occupational diseases, dangerous occurrences, and certain gas incidents.
A work-related death must be reported if it results from a workplace accident. That applies to employees and, in some cases, non-workers affected by work activity.
Specified injuries are serious injuries defined by the regulations. These include fractures other than fingers, thumbs, and toes, amputations, injuries likely to cause permanent loss of sight or reduction in sight, crush injuries to the head or torso causing damage to internal organs, serious burns, scalping requiring hospital treatment, and loss of consciousness caused by head injury or asphyxia.
An over-seven-day injury is also reportable. If a worker is unable to perform their normal duties for more than seven consecutive days after a work-related accident, this must be reported. The day of the accident is not counted, but weekends and rest days are.
Occupational diseases can also fall under RIDDOR where a doctor has made a diagnosis and the disease is linked to work exposure. Examples can include carpal tunnel syndrome, severe cramp of the hand or forearm, occupational dermatitis, hand-arm vibration syndrome, asthma, and tendonitis in certain circumstances.
Dangerous occurrences are specific near-miss events with the potential to cause serious harm. These are listed in the regulations and often include equipment failure, electrical short circuits causing fire or explosion, collapse of lifting equipment, or accidental release of a hazardous substance. Not every near miss is reportable, but some clearly are.
When an incident is not reportable
This is where confusion often happens. If an employee trips over their own bag in the office and suffers a minor bruise, that may need to be recorded internally, but it is unlikely to be reportable under RIDDOR. If someone is absent for only a few days, it will not meet the over-seven-day threshold. If there is no work-related cause, it may not fall within the regulations at all.
There is also an important distinction between internal recording and external reporting. Employers should still keep accident records where required, even if the incident does not need to be reported under RIDDOR. A complete accident book and good internal procedures remain essential.
Who is responsible for reporting?
The responsibility usually falls on the employer, but it can also apply to self-employed people and the person in control of work premises. In practice, many organisations assign this task to a manager, health and safety lead, HR team member, or compliance officer.
That said, the legal duty sits with the responsible person, not simply the individual who witnessed the accident. If reporting is part of your job role, you need to know your organisation’s procedure, reporting timescales, and what information should be gathered straight away.
For businesses, this is one reason staff training matters. A reportable incident can be missed if frontline workers are unsure what counts, or if managers do not understand the threshold.
How quickly must a RIDDOR report be made?
Some incidents must be reported without delay. Fatalities and specified injuries should be reported as soon as possible. Over-seven-day injuries must be reported within 15 days of the accident. Cases of occupational disease should be reported once the diagnosis is confirmed and linked to work.
Speed matters, but accuracy matters too. Rushing a report without the right facts can create problems later. The best approach is to make sure the injured person receives appropriate support first, secure the scene if necessary, gather the evidence, and then submit the report within the legal timeframe.
What information is usually included in a report?
A RIDDOR report generally includes the date, time, and location of the incident, details of the injured person, what happened, the nature of the injury or occurrence, and why it is considered reportable. Clear records make investigations easier and help demonstrate that the organisation responded properly.
It is also good practice to keep supporting documentation such as witness statements, risk assessments, training records, maintenance logs, and photographs where relevant. These records are not all part of the report itself, but they may become important if questions are raised later.
Common examples by sector
In health and social care, a report may be required if a staff member sustains a specified injury while moving and handling, or if a work-related exposure leads to a diagnosed occupational illness. In construction, dangerous occurrences are especially relevant because equipment failure, structural collapse, and electrical incidents can fall within the regulations.
In schools and training environments, the position can be more nuanced. Not every pupil injury is reportable, and the same applies to visitors. Usually, there needs to be a clear connection to the way work was carried out, the condition of the premises, or unsafe equipment. In hospitality and food settings, severe burns, petrol-related events, and over-seven-day injuries can all become reportable depending on the circumstances.
This is why sector-specific health and safety training can make such a difference. The law is the same, but the practical examples vary from one workplace to another.
What happens if you fail to report?
Failure to report a reportable incident can lead to enforcement action. It may also suggest broader weaknesses in health and safety management. If an organisation misses a legal reporting duty, regulators may question its training, supervision, record-keeping, and risk control measures.
There is also the reputational impact. For employers, weak compliance can affect staff confidence, inspections, and trust. For workers, especially those building careers in regulated sectors, understanding reporting duties is part of professional competence.
How to stay compliant with RIDDOR
The strongest approach is to build RIDDOR into your wider health and safety system rather than treating it as a one-off admin task. That means having a clear accident reporting procedure, training staff on what to escalate, reviewing incidents properly, and keeping records organised.
It also helps to refresh knowledge regularly. Health and safety responsibilities can shift as people move into supervisory roles or join new sectors. A short course or refresher can close gaps quickly, especially for learners balancing work and development. For many adults studying flexibly, this kind of practical knowledge has immediate value because it supports both compliance and employability.
If you have been wondering what is RIDDOR, the simplest answer is this: it is the legal framework for reporting serious work-related health and safety incidents in the UK. Knowing the difference between an incident that should be recorded and one that must be reported is not just useful knowledge. It is part of protecting people, meeting your responsibilities, and building a safer place to work.
