Occupational safety tool
Enter the period’s figures and get the rates on the ADOSH-SF basis. The tool returns the rate and the basis it was computed on — it does not judge the result.
🧪 Example figures
Illustrative only — not typical values, not a recommendation. Replace with your own.
↳ Switch the basis to the US 200,000-hour option and the same performance reads five times lower - which is why a rate without its basis compares to nothing.
Employees only — see the counting rule below
Total days lost across those injuries — drives the severity rate
Actual hours worked by employees, including overtime
Recorded with the result. Two entities with identical performance can differ several-fold on this choice alone.
Reporting period (optional): Q1 2026
Lost-workday definition used: Calendar days — every day after the injury until return
Reporting basis: Per 1,000,000 hours — ADOSH-SF basis
Frequency rate (LTIFR)
1.38
per 1,000,000 hours
Severity rate (LTISR)
23.45
per 1,000,000 hours
Restated on the other basis
Per 200,000 hours — US basis (OSHA) — LTIFR 0.28 · LTISR 4.69
Formula
LTIFR = 2 × 1,000,000 ÷ 1,450,000 = 1.38
LTISR = 34 × 1,000,000 ÷ 1,450,000 = 23.45
Under Mechanism 6.0 of the ADOSH-SF framework, only employees’ injuries and lost workdays count toward the entity’s rate. Contractor and third-party injuries are reported but excluded from the rate calculation. Folding contractor injuries into the figure inflates your rate with no regulatory basis for doing so.
No UAE authority publishes an LTIFR qualification threshold, and a high rate is not in itself a breach of ADOSH-SF — failing to report is. Any tool that prints "compliant" or "qualified for tenders" against a number is asserting a rule that does not exist. Compare your rate against your own trend and your client’s stated contractual requirement.
