The Definition of Near Miss

Definition of Near Miss

A near miss is an unplanned event that had the potential to cause injury, illness, property damage or environmental harm, but did not, whether because of chance, timing, distance or someone's quick reaction. Near misses are also called close calls, near hits or good catches. A near miss is a warning sign, not a non-event: the same conditions that produced it could easily cause an actual incident next time.

Near misses happen far more often than injuries. Classic safety research, such as Frank Bird's accident ratio studies, found that each serious injury is accompanied by many minor injuries and a much larger number of no-injury events. The exact ratios are debated, and not every near miss points to a fatal risk, but the core idea holds: near misses give organizations a chance to find and fix hazards before someone is hurt.

Despite their value, near misses are often underreported. Workers may not see the point of reporting something that caused no harm, may fear blame, or may find the reporting process too slow. Building a strong near miss program is one of the most effective ways to improve safety performance.

Examples of Near Misses

• A tool falls from a scaffold and lands next to a worker below.
• A forklift and a pedestrian nearly collide at a blind corner.
• A worker slips on an oil spill but catches themselves before falling.
• A gas detector alarms during confined space entry and workers evacuate safely.
• A trailer starts to move away from a loading dock while a forklift is inside, but stops before a gap opens.
• A machine starts up while a technician's hand is nearby because it was not locked out.

Some near misses involve high-potential events, sometimes called serious injury and fatality (SIF) precursors, where the outcome could easily have been fatal. These deserve the same depth of investigation as a serious injury.

Building an Effective Near Miss Program

Make reporting easy

Reports should take a minute or two to submit, from wherever the work happens. Mobile apps, QR codes, short paper cards and anonymous options all help. The fewer required fields, the more reports an organization usually receives.

Make reporting safe

Workers will not report if they expect to be blamed or disciplined. A just culture separates honest mistakes from reckless behavior, so people feel safe sharing what happened.

Capture useful information

A good report captures what happened, where and when, who was nearby, what conditions or actions contributed, and what could have happened if circumstances had been slightly different. Photos are especially helpful.

Investigate based on potential

Not every near miss needs a full investigation. Scale the response to the worst credible outcome. A slip with no fall potential may need a quick fix, while a near miss involving a suspended load or energized equipment deserves a full incident investigation.

Act and close the loop

Assign each finding a corrective action with an owner and due date, and tell the person who reported it what was done. Nothing builds reporting faster than visible action.

Track trends

Near miss reporting rates and closure times are useful leading indicators. A drop in reports does not always mean fewer hazards. It may mean workers have stopped reporting, which can be an early sign of normalization of deviance.

Example of Near Miss

At a distribution center, a worker reached for a falling toolbox from a high shelf and it landed inches from his foot. He reported it through the site's mobile app in under a minute, attaching a photo of the shelf. The supervisor found that heavy items were being stored above shoulder height because lower shelves were full of slow-moving stock.

The site reorganized the racking so heavy items stayed between knee and shoulder height, added lips to the upper shelves and shared the photo at the next toolbox talk. Two other workers then reported similar storage problems in another aisle, which were fixed the same week.

Frequently Asked Questions: Near Miss

What is the difference between a near miss and an incident?

An incident results in actual harm, such as an injury, illness, property damage or environmental impact. A near miss has the same potential for harm but, because of timing, distance or a quick reaction, no harm occurred. Both point to the same underlying hazard.

Why should employees report near misses if nobody got hurt?

Near misses are early warnings. Reporting them lets an organization fix the root cause before it produces an injury, rather than waiting for one to happen first.

What information should a near miss report include?

What happened, where and when it occurred, who was involved or nearby, what conditions or actions contributed, and what could have happened if circumstances had been slightly different.

How can a company encourage more near miss reporting?

Use non-punitive reporting, make it fast and easy to submit a report, including anonymously, recognize people who report and visibly act on what gets reported.

Are near misses required to be reported to OSHA?

No. OSHA recordkeeping under 29 CFR 1904 covers actual injuries and illnesses, not near misses. Some other countries do require certain dangerous events to be reported. See notifiable incident.
