Struggling to Calculate TRIR or DART? You’re Not Alone.

If you’ve ever had to manually calculate TRIR (Total Recordable Incident Rate) or DART (Days Away, Restricted, or Transferred) rates, you know it’s tedious. Between digging through spreadsheets and double-checking OSHA formulas, it’s easy to make mistakes—or delay reporting altogether.

That’s why we built the AEGIS Safety Metrics Calculator, a lightweight, web-based tool that makes tracking your safety performance simple and reliable.

What It Does

• Calculates TRIR and DART using official OSHA formulas

• Uses a clean, mobile-friendly interface

• Requires no downloads or spreadsheets

• Instantly generates your results with just a few inputs

Why It Matters

Safety professionals already juggle enough. Whether you’re preparing for a leadership meeting, filling out an OSHA log, or updating your safety dashboard, you need numbers you can trust—fast.

This tool ensures you’re using accurate math (no more confusion between TRIR and “TCRI”) and gives you OSHA-aligned results you can drop straight into your reports.

How to Use It

Just go to:
