Here is a safety number where a higher result can be good news. The near miss frequency rate counts the events that could have hurt someone but did not. A site that reports lots of them is usually a site where people are paying attention.
Enter your near misses and hours worked below to get your rate.
What is the near miss frequency rate?
The near miss frequency rate (NMFR) shows how many near misses were reported for every 1,000,000 hours worked. It is a leading measure, which means it looks at warning signs before injuries happen, not after.
The NMFR formula
NMFR = (Number of near misses x 1,000,000) / Total hours worked
Some companies use 200,000 hours as the base. Use the one your system requires and write it next to the number.
Worked example
A site reported 90 near misses in a year. The team worked 450,000 hours.
NMFR = (90 x 1,000,000) / 450,000 = 200
That is 200 near misses per million hours worked. If the next year the site reports 135 near misses over 460,000 hours, the NMFR is 293. In most cases that is a positive change, as long as the injury rate is not going up at the same time.
Why a higher number is often good
Most safety numbers work like golf: low is good. NMFR is different. Near misses happen on almost every site, whether or not they are reported. If your rate is very low, it is far more likely that people are not reporting than that nothing is happening.
A rising NMFR together with a falling injury rate is a classic sign of a healthy safety culture. People speak up, hazards are fixed, and fewer people get hurt.
What counts as a near miss?
A near miss is an event that could have caused injury or damage but did not, by luck or by quick reaction. Some examples are a load that slips and lands where no one is standing, a worker who trips but does not fall, or a vehicle that brakes just in time.
How to improve near miss reporting
- Make the form short, and allow reporting by phone or WhatsApp.
- Never punish a person for reporting.
- Reply to each report quickly and say what will be done.
- Share fixes at toolbox talks so people see that it works.
- Thank people who report, in a simple and honest way.
What to do with the reports
Reports are not a count to be admired. They are a list of hazards. Group them by type and place, find repeat events, and fix the most dangerous ones first. The risk matrix calculator can help you decide which ones come first. The accident pyramid calculator shows the link between near misses and serious injuries.
Common mistakes
- Setting a target for fewer near misses, which pushes people to hide them
- Counting only the ones that supervisors notice
- Not following up, so people stop reporting
- Judging the rate without looking at injury numbers
- Mixing bases between reports
Step by step
- Count the near misses reported in the period.
- Add up the total hours worked.
- Multiply the near misses by 1,000,000.
- Divide by the hours.
- Compare it with your injury rate for the same period.
Example: tracking it every month
A site reports 6 near misses in January over 38,000 hours, which is a rate of 158. In February it reports 11 over 36,000 hours, which is a rate of 306. That is nearly double. Rather than panic, the safety officer checks the injuries: none. The jump came from a new reporting card and a toolbox talk on what counts. Reporting went up, and the site became more aware.
Using the result in your safety meetings
Share a short list of the near misses reported each month, with what was done about each. People like to see that their report led to a change, such as a new guard, a repainted walkway or a changed schedule. That small loop of report, fix and feedback is what keeps the reporting rate healthy.
Frequently asked questions
What is a good near miss frequency rate?
There is no ideal number. A rising rate with falling injuries usually shows better reporting.
Is a high NMFR bad?
Not usually. It often means workers trust the system and report more.
What is the difference between a near miss and an incident?
A near miss has no injury or damage. An incident may include injury, damage or both.
Which base should I use?
Use 1,000,000 hours unless your client asks for another. Always state the base.
How can I get more reports?
Make it easy, protect people who report and show that action follows each report.
