Occupational safety tool

Injury Frequency & Severity Rate (LTIFR / LTISR)

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.

Period figures

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.

Result

Enter the injuries and the hours worked to compute.

The counting rule most tools get wrong

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.

Why this tool gives you no pass/fail

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.
