Near miss: definition, examples, and how to report one
A near miss is an unplanned event that could have caused injury, illness, or damage but didn’t – a close call where harm was avoided by luck, good timing, or quick action.
The UK’s Health and Safety Executive (HSE) describes a near miss as an event that, although it caused no harm, had the potential to cause injury or ill health.
Because no one was hurt and nothing was broken, near misses are easy to shrug off. But each one is a warning – a signal that a hazard exists and that next time, the outcome may not be so favourable. For health and safety teams, near misses are some of the most valuable data you can collect – they let you fix a problem before it becomes an accident.
In one line: A near miss is a “near hit” – an incident that almost caused harm. Spotting and reporting them is how proactive safety teams prevent serious accidents.
Near miss vs accident vs incident vs hazard
These four terms are often used interchangeably on the ground, but they mean different things, and getting them right matters for how you record, investigate, and report each event.
| Term | What it means | Was there harm? |
| Hazard | Something with the potential to cause harm (e.g., a trailing cable, a spill, a faulty machine). No event has happened yet | No, but it is a source of risk |
| Near miss | An unplanned event that could have caused harm but didn't | No, but it nearly did |
| Accident | An unplanned event that does result in injury, illness, or damage | Yes |
| Incident | The umbrella term covering all of the above - near misses, accidents, and dangerous occurrences | Sometimes |
The simplest way to remember it: a hazard is the source of danger, a near miss is the warning event, and an accident is the outcome you were trying to avoid. A near miss and an accident often share the exact same root cause.
Near miss examples in the workplace
Near misses look different in every industry, but the pattern is always the same – a hazard nearly caused harm and didn’t. Here are some examples across different scenarios.
| Sector | Near miss example |
| Construction | A scaffold pole falls from height but lands in an empty exclusion zone |
| Manufacturing | A machine guard is left open, but the operator notices before reaching in |
| Warehouse & logistics | A forklift and a pedestrian nearly collide at a blind corner |
| Transport | A delivery driver brakes hard to avoid a vehicle pulling out - no contact made |
| Healthcare | The wrong medication is drawn up but caught at the bedside check before it's given |
| Food & beverage | A worker slips on a wet floor near a fryer but grabs a rail and stays upright |
| Office | An employee trips on a trailing cable but doesn't fall |
Each of these is a learning opportunity. When properly logged and investigated, they tell you exactly where your controls are slipping, before they cost someone an injury.
Why do near misses matter?
Decades of safety research shows that serious accidents are almost never the first sign of trouble. They sit at the top of a much larger base of minor events and near misses.
Heinrich’s Triangle (1931): for every major injury, H.W. Heinrich observed roughly 29 minor injuries and 300 no-injury accidents (near misses).
Bird’s Triangle (1969): Frank Bird’s study of 1.7 million incidents found a ratio of 1 serious injury to 10 minor injuries, 30 property-damage events and 600 near misses.
HSE estimate: the Health and Safety Executive estimates there are, on average, around 90 near misses for every injury at work.
The lesson for safety leaders is consistent across all three – near misses are the widest, earliest and most frequent warning you’ll ever get. Capture them, and you can act on hundreds of warnings before the one accident that would otherwise have happened. Ignore them, and you’re choosing to learn only when someone gets hurt.
Near misses are a leading indicator – they tell you about risk before harm occurs. Injury and lost-time rates are lagging indicators – they only tell you once the damage is done. The whole point of near miss reporting is to manage safety with leading indicators, not just count the lagging ones.
Is it a legal requirement to report a near miss?
Under UK law (the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, or RIDDOR), an everyday near miss does not need to be reported to the HSE. However, a specific group of high-potential near misses, known as “dangerous occurrences” must be reported by law. RIDDOR lists 27 categories of dangerous occurrence in Schedule 2, including things like the collapse or failure of lifting equipment, plant or equipment contacting overhead power lines, and explosions or fires that stop work for more than 24 hours.
Generally, everyday near miss (e.g. a trip with no fall) do not need reporting to the HSE under RIDDOR, however you should still record and investigate these instances internally.
A near miss that’s a “dangerous occurrence” (one of the 27 Schedule 2 categories) must be reported to the HSE under RIDDOR, even though no one was hurt.
Beyond RIDDOR, employers have a broader duty of care under the Health and Safety at Work etc. Act 1974 to manage risk. Recording near misses is one of the clearest ways to demonstrate you’re doing that to your workforce, regulators, insurers, and clients.
If you’re unsure whether a specific event is RIDDOR-reportable, the HSE’s reportable incidents guidance is the definitive source.
Why do near misses go unreported?
Despite being the most valuable safety data available, near misses are also the most under-reported. The usual reasons are:
- Fear of blame – workers worry that reporting will get them or a colleague in trouble.
- “No harm, no foul” – if nothing happened, reporting can feel like a waste of time.
- Friction – paper forms and back-at-the-desk systems mean events are forgotten before they’re logged. This is where dedicated health and safety software helps.
- Normalisation of risk – when a near miss happens often enough, it stops feeling like a near miss at all.
- No visible follow-up – if nothing changes after an incident report is submitted, people stop bothering.
Every unreported near miss is a warning you never got to act on. The fix is cultural and practical – make reporting blame-free, make it take seconds, and visibly close the loop so people see their reports lead to change.
How to report a near miss
An effective near miss reporting process is fast, simple, and consistent. Here’s the standard sequence:
For frontline teams:
- Make the area safe. Before anything else, remove the immediate hazard or make the area safe so no one else is exposed to danger.
- Capture it in the moment. Record what happened as soon as possible, ideally on the spot, while the details are fresh. The longer the gap, the more information is lost.
- Describe what happened and what could have happened. Note the location, time, conditions, people present and the realistic worst-case outcome.
- Submit it to the right person. Route the report to whoever owns safety actions for that area so they can assess the risk.
For safety teams:
- Investigate the root cause. Look past the immediate trigger to why it happened i.e., the failed control, not just the event.
- Act and feed back. Assign corrective actions, track them to completion, and tell the workforce what changed. This is what keeps reports coming.
Reporting friction is one of the biggest barriers to capturing near misses. With a near miss reporting app, frontline workers can log a near miss from their phone – with a photo and GPS location – in under 60 seconds, online or offline.

What to include in a near miss report
A useful near miss report captures enough information to investigate the event and spot trends later. As a minimum:
- Date, time and exact location
- A clear description of what happened
- The realistic potential outcome (what could have happened)
- People involved or present, and any witnesses
- The work activity and conditions at the time
- Immediate action taken to make things safe
- Suggested corrective or preventive measures
Standardising these fields, for example, with pre-set hazard types and cause categories, makes your data far easier to analyse across sites and over time. It also makes it simpler for reporters who are submitting information.
How to build a near miss reporting culture
For health and safety leaders, the hard partis getting people to report near misses consistently. A few principles will help:
- Lead with learning, not blame. Reassure people that reporting improves safety and isn’t used to punish. Reporting should be a visible part of your wider safety culture.
- Remove every barrier. The easier it is to report, the more you’ll capture. Mobile, offline-capable reporting consistently beats paper and spreadsheets.
- Recognise the behaviour. Acknowledge good catches. Some organisations use positive safety observations and recognition schemes to reinforce reporting.
- Always close the loop. Show people that reports lead to action. Nothing kills reporting faster than silence.
When organisations make reporting frictionless, the numbers move fast. With Notify, Epta saw a 100% increase in near miss reports, Product Care Group saw a 5x rise, and Stadler Rail UK saw an 87% increase.
Turning near miss data into fewer accidents
Capturing near misses is only the first step. The value comes from what you do with the data. A connected reporting system lets you:
- Spot trends and patterns across sites, departments, and hazard types before they cause harm.
- Prioritise resource where the leading indicators say risk is concentrated.
- Prove the impact of your safety programme to the board and regulators with real numbers.
- Shift from reactive to proactive safety management – managing risk by the warnings you collect, not the injuries you suffer.
This is the core of a modern safety approach. Every near miss becomes actionable data, and that data drives a measurable reduction in accidents and lost-time injuries. Notify’s Incident Reporting Software and Safety Intelligence Dashboards are built to turn frontline reports into exactly that.

FAQs
A near miss is a close call – an unplanned event that could have caused injury, illness, or damage but didn’t. For example, a worker slips on a wet floor but catches themselves before falling. No one was hurt, but the hazard that nearly caused harm is still there.
The difference between a near miss and an accident is the outcome. A near miss could have caused harm but didn’t; an accident actually results in injury, illness, or damage. Both often share the same root cause – the thing separating them could have been luck or quick action. This is why near misses are treated as early warnings of accidents.
Most everyday near misses are not reportable under RIDDOR. However, near misses that fall into one of the 27 “dangerous occurrence” categories in Schedule 2 of RIDDOR – such as the failure of lifting equipment or contact with overhead power lines – must be reported to the HSE, even though no one was injured.
Common examples include a scaffold pole falling into an empty area, a forklift nearly hitting a pedestrian, the wrong medication being caught before it’s administered, or someone tripping on a cable without falling.
Each is an event that nearly caused harm.
Near misses are leading indicators of accidents. Research suggests there are dozens to hundreds of near misses for every serious injury. Reporting them lets you identify and fix hazards before they cause harm, rather than only learning lessons after an injury has already happened.
At a minimum, a near miss report should include: the date, time and location; a description of what happened and what could have happened; who was involved or present; the conditions at the time; the immediate action taken; and suggested measures to prevent it from recurring.
The more detail, the better for investigation.
