Fast calculations for supervisors, auditors, and safety teams. Review exposure hours, reports, and incident frequency. Turn field observations into practical actions that reduce risk.
Use direct hours if you already know total exposure hours. Otherwise, the tool will calculate hours from workforce size, days worked, and daily hours.
Total Hours Worked = Workers × Days Worked × Hours per Day
If direct hours are entered, the calculator uses those hours instead.
Near Miss Rate = (Near Miss Count × Multiplier) ÷ Total Hours Worked
Recordable Rate = (Recordable Incidents × Multiplier) ÷ Total Hours Worked
First Aid Rate = (First Aid Cases × Multiplier) ÷ Total Hours Worked
The standard 200,000-hour multiplier is common for comparing incident frequency across projects. You can switch to another multiplier when company policy or client reporting rules require it.
| Period | Work Area | Near Misses | Hours Worked | Near Miss Rate |
|---|---|---|---|---|
| January 2026 | Foundation | 3 | 14,500 | 41.38 |
| February 2026 | Steel Works | 5 | 18,200 | 54.95 |
| March 2026 | MEP Install | 4 | 16,900 | 47.34 |
| April 2026 | Finishing | 6 | 21,300 | 56.34 |
Example rates above use a 200,000-hour multiplier for comparison.
A near miss rate measures how often near miss events are reported relative to hours worked. It helps teams compare reporting frequency across projects, shifts, contractors, or time periods.
Hours worked better reflect exposure. Two projects can have the same crew size but very different working time, overtime, or subcontractor presence. Exposure-based rates are more comparable.
Use the multiplier required by your company, client, or reporting framework. Many teams use 200,000 hours because it aligns with common incident rate reporting conventions.
Not always. A higher rate may indicate more hazards, but it can also show stronger reporting culture. Review inspections, corrective actions, and incident severity beside the rate.
Yes. If you already have payroll, timesheet, or project control totals, enter direct hours. The calculator will prioritize that value over the workforce-based estimate.
Include all hours that fall under the reporting boundary you are evaluating. For project-level safety reviews, that usually means employee and subcontractor exposure hours together.
Look for repeat work areas, task types, time-of-day patterns, and corrective action delays. Near miss data is most useful when it triggers prevention steps and follow-up verification.
Yes. After calculation, use the CSV and PDF buttons to save a shareable summary. Exports are useful for internal meetings, audits, toolbox talks, and monthly dashboards.
