What is a Near Miss, and Why You Should Report It

A near miss is an unplanned event that did not result in injury or damage but had the potential to do so. In health and safety, near misses are early warnings: the same circumstances that caused a near miss today could cause a serious injury tomorrow. Recording and acting on near misses is one of the most effective and least expensive ways to prevent accidents, which is why a strong near miss culture matters so much.

What counts as a near miss

A near miss is any incident where harm was narrowly avoided, whether by good luck, quick reactions, or simply timing. Examples include a tool falling from height but landing where no one was standing, someone slipping on a wet floor but catching themselves, a vehicle nearly reversing into a pedestrian, or a faulty electrical socket spotted before it caused a fire. No one was hurt and nothing was damaged, but the potential was clearly there.

It is helpful to distinguish near misses from related terms. An accident results in injury or ill health. A dangerous occurrence is a specific category of serious near miss that is reportable under RIDDOR. A hazard is a condition with the potential to cause harm. A near miss is the event where that potential was almost realised.

Why near misses matter so much

Near misses matter because they reveal the weaknesses in your controls before anyone is hurt. Safety research has long pointed to the idea that serious injuries are preceded by far larger numbers of minor incidents and near misses arising from the same underlying causes. If you only react to injuries, you are managing safety by waiting for people to get hurt. If you capture and act on near misses, you can fix the underlying problem while the cost is still only a report, not an injury.

The value of a reporting culture

The biggest barrier to near miss reporting is culture. People often do not report near misses because they fear blame, think it is not worth the bother, or assume nothing will be done. The result is that valuable warnings are lost. A strong reporting culture turns this around by making it easy to report, responding constructively rather than looking for someone to blame, and visibly acting on what is reported so people see that it makes a difference.

• Make it easy: provide a quick, simple way to report, ideally from a phone, so reporting takes seconds.

• Stay blame free: focus on the circumstances and the fix, not on punishing the person who reports.

• Act and feed back: investigate, make changes, and tell people what was done, so reporting feels worthwhile.

• Lead by example: when managers report and act on their own near misses, others follow.

How to investigate a near miss

Investigating a near miss uses the same approach as investigating an accident, just without an injury to deal with. Establish what happened and the sequence of events, identify the immediate causes and, more importantly, the underlying root causes, and decide what needs to change to prevent a recurrence. The aim is not to find someone to blame but to understand why the controls failed or were missing, and to strengthen them. Recording the findings and the actions taken closes the loop.

Are near misses reportable?

Most near misses do not need to be reported to the HSE; they are recorded internally and used to improve safety. However, a specific category of serious near miss, known as a dangerous occurrence, is reportable under RIDDOR. Examples include the collapse of scaffolding, the failure of lifting equipment, or the accidental release of a dangerous substance. It is worth screening significant near misses against the RIDDOR dangerous occurrence list so you do not miss a reportable event.

Turning near miss data into prevention

The real value of near miss reporting comes from looking at the data over time, not just individual reports. Patterns often emerge: a particular location, task, time of day, or piece of equipment that generates repeated near misses. These patterns point to where your next serious accident is most likely to come from, and therefore where to focus your improvement effort. Reviewing near miss trends in your regular safety meetings turns scattered reports into targeted prevention.

Frequently asked questions

• What is a near miss in health and safety: An unplanned event that did not cause injury or damage but had the potential to do so.

• What is the difference between a near miss and an accident: An accident results in injury or ill health, while a near miss is an event where harm was narrowly avoided.

• Should near misses be reported: Yes, internally. Capturing and acting on near misses prevents future accidents. Certain serious near misses are also reportable to the HSE as dangerous occurrences.

• Why do people not report near misses: Usually fear of blame, thinking it is not worth it, or assuming nothing will be done. A blame free, responsive culture overcomes this.

• Are near misses reportable under RIDDOR: Most are not, but specific dangerous occurrences listed under RIDDOR must be reported to the HSE.
