LTIFR: What Counts and What Does Not — Three Errors That Make Your Rate Incomparable

LTIFR is simple in its formula and deceptive in its interpretation. Three things change it several-fold without your real performance changing at all: the reporting basis, the lost-day definition, and folding in contractor injuries. This guide separates what the framework states from what is merely assumed.

The formula and the basis

The framework''s Glossary of Terms defines the lost time injury frequency rate as:

injuries × 1,000,000 ÷ hours worked

The basis is one million hours. This is the first error: some systems use a 200,000-hour basis, on which the rate is five times smaller. A contractor quoting 0.4 on the US basis is 2.0 on the Abu Dhabi basis. Comparing the two without normalising the basis reverses the conclusion entirely.

The second error: who counts

Mechanism 6.0 of the framework, section 2(e), states that 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 — common, and usually done in good faith — inflates your rate with no regulatory basis and makes it incomparable to rates computed correctly.

The third error: what a "lost day" is

Calendar days count every day after the injury until return. Scheduled workdays count only rostered shifts missed. The gap is large: an injury followed by two weeks away can be 14 days, or 10, or 6, depending on the definition and the shift pattern.

So a figure without its definition is comparable to nothing — not even to the same entity''s earlier periods if the definition changed between them. Record the definition used with every period.

What the framework does not state

No UAE authority publishes a qualification threshold for LTIFR. A high rate is not in itself a breach of the framework — failing to report is. Reporting is quarterly on Form E/E2 under Mechanism 6.0.

Any tool or table that prints "compliant", "non-compliant" or "qualified for tenders" against a number is adding a rule that is not there. Compare your rate against your own trend and against your client''s written contractual requirement — both are real references, unlike an assumed threshold.

The severity rate

Computed on the same basis: lost workdays × 1,000,000 ÷ hours worked. Read alongside the frequency rate it separates an entity with many minor injuries from one with few severe ones — a distinction the frequency rate alone conceals.

Frequently Asked Questions

Do I count a subcontractor''s injury in my rate?

No, per Mechanism 6.0 s2(e) — it is reported but excluded from the entity''s rate.

A contractor shows 0.4 and mine is 1.8. Is their performance better?

You cannot tell until you know their basis. If 0.4 is on a 200,000-hour basis it is 2.0 on the million-hour basis — higher than yours. Ask for the basis first.

What rate is acceptable?

No UAE authority publishes a threshold. The two real references are your own trend across periods and the written requirement in your client''s contract.
