Accident or Incident? The 5 Terms That Decide What You Report
Ask five people in an organisation to define an accident, a near miss and an incident and you will get five answers. Most of them will be reasonable, and the differences between them will be quietly deciding what gets recorded, what gets reported and what gets investigated.
That matters because reporting obligations attach to categories, not to how serious something felt. An event correctly classified goes into the right process. An event classified loosely goes into the accident book, or nowhere.
Five terms, what each means, and what each obliges you to do.
1. Incident: the broadest term
What it means: an unplanned event. It covers everything below.
Incident is the umbrella word, which is why it is the least useful on its own. An organisation whose system records everything as an "incident" and stops there has collected events without classifying them, and classification is what triggers the obligations.
What it obliges: nothing in itself. It is a container, and the work is deciding which of the categories below applies.
Practical point: if your incident form has no field forcing a category, your data cannot tell you what is reportable. That is the single most common design fault in incident systems.
2. Accident: an unplanned event that caused harm
What it means: in health and safety usage, an unplanned event that resulted in injury, ill health or damage. The distinguishing feature is that something actually happened to somebody or something.
What it obliges: recording, always. Reporting, only if it falls within a defined category.
Most accidents are not reportable. An accident causing a cut finger and a day off is recorded in the accident book and goes no further. It becomes reportable if it results in death, a specified injury, or incapacity for routine work for more than seven consecutive days.
Practical point: the word people argue about is "unplanned". A foreseeable consequence of a known hazard is still an accident. Whether it was foreseeable is a question for the investigation, not the classification.
3. Near miss: the same event without the harm

What it means: an unplanned event that had the potential to cause injury, ill health or damage, and did not.
What it obliges: nothing under the reporting regulations, unless it happens to be a dangerous occurrence. And it is the most valuable category you have.
The logic is straightforward. A near miss is a free lesson: the same circumstances that produced no harm this time can produce harm next time, and you have been told about it at no cost.
Our guide to near misses covers the concept in detail.
Practical point: an organisation recording plenty of accidents and almost no near misses does not have good luck. It has a reporting problem, because near misses outnumber accidents in any workplace. That is a diagnostic worth applying to your own data today.
4. Dangerous occurrence: a named near miss that is reportable
What it means: a specified event listed in the regulations, reportable even where nobody was hurt.
This is the category most people have never heard of, and it is the exception to the rule that near misses are not reportable.
Regulation 7 of the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 provides for reportable dangerous occurrences, which are set out in a schedule. Only listed events qualify.
The list is largely industrial, and several entries reach ordinary premises: the collapse or failure of load-bearing parts of lifts and lifting equipment, electrical short circuits or overloads causing fire or explosion, and certain accidental releases of substances.
What it obliges: notification without delay and a report, in the same way as a serious injury.
Practical point: a lift failure in an office building can be a dangerous occurrence. Most facilities teams would treat it as a maintenance matter and never consider reporting it.
5. Occupational disease: a different trigger entirely
What it means: a diagnosed condition, listed in the regulations, where the work is likely to have caused it or made it worse.
Regulation 8 covers reportable diseases, including carpal tunnel syndrome, severe cramp of the hand or forearm, occupational dermatitis, hand-arm vibration syndrome, occupational asthma, tendonitis of the hand or forearm, and cancers and diseases attributable to occupational exposure.
What it obliges: reporting, triggered by receiving a written diagnosis from a doctor, not by somebody reporting symptoms.
Practical point: this is the category office-based organisations miss most often, because it does not arrive as an event. It arrives as a piece of paper, often through HR or occupational health rather than through the safety process. Somebody needs to be watching for it.
The five, in short
| Term | What it is | What it triggers |
|---|---|---|
| Incident | Any unplanned event | Classification |
| Accident | Unplanned event that caused harm | Always record; report if in a category |
| Near miss | Potential harm, none caused | Record and learn; not reportable |
| Dangerous occurrence | A listed near miss | Notify and report |
| Occupational disease | Listed condition, work-related | Report on written diagnosis |
Rows four and five are where office-based organisations most often fail, because neither looks like the kind of event people expect to report.
Why the words matter more than they sound
Three consequences of getting this wrong.
Under-reporting by misclassification. An event logged as a near miss when somebody was actually off work for eight days is a missed reportable injury, and the deadline runs from the accident regardless.
Investigation that never happens. Many organisations investigate accidents and log near misses. That is the wrong way round if you want to prevent harm, because the near miss is the one you can learn from without a cost.
Data you cannot use. Where categories are applied loosely, trends cannot be seen. A pattern of the same near miss in the same place is a warning. A pile of undifferentiated "incidents" is not.
Our guides to the accident book and recording accidents at work cover the recording side, and HSE's RIDDOR pages set out the reporting requirements.
What to keep, and for how long
Regulation 12 requires the responsible person to keep a record of reportable incidents, and of over-three-day injuries, for at least three years.
Records should capture the date and method of reporting, the date, time and place of the event, personal details of those involved, and a brief description. Paper or electronic is fine, provided it can be produced on request.
Keep near miss records too. They are not legally required and they are the most useful safety data most organisations hold.
For international groups
Two considerations.
The categories differ by country. Several jurisdictions covered in this series include events that British definitions exclude. Kuwait and Israel both treat accidents on the journey to or from work as reportable. Bahrain makes vehicle accidents on the premises reportable in their own right, and uses a seven-day absence trigger with its own counting rule.
The trigger points differ too. Slovakia requires a written record within eight days with the injured person involved. Morocco requires a report to two inspectorates within fifteen days. Croatia requires a committee session within two working days of a fatality.
An incident form built around British categories will not capture what other entities must report. Building the categories in per entity is the fix, and holding them in one register is where health and safety consultants and software are worth more together than either alone. Periodic health and safety audits establish whether reportable events were actually reported.
Where Arinite fits
Arinite builds incident processes that classify events correctly at the point of entry, which is what makes everything downstream work. We support 1,500+ businesses across 50+ countries and protect 100,000+ employees, with 95%+ client retention over 15+ years.
Our health and safety consultants work extensively with legal, finance and banking and IT and software organisations, where incident management is mature in other domains and safety often sits outside it.
Where entities sit in several countries, our global health and safety consultants establish which categories and deadlines apply to each, and our international health and safety consultants keep that current.
If your incident log records plenty of accidents and almost no near misses, a free gap analysis is the right place to start.
