Which base should I use in the UAE?

  • 200,000 hours — OSHA convention; the most common format for ADOSH-SF (formerly OSHAD) reporting and international benchmarking.
  • 1,000,000 hours — widely used by UAE main contractors and joint ventures when reporting to boards or clients; produces larger-magnitude numbers.
  • Always state your base alongside the rate — a TRIR of 1.5 at 200k is not the same as 1.5 at 1M.

Frequently asked questions

What is the difference between the 200,000 and 1,000,000 man-hour base?

The 200,000-hour base is the OSHA / ADOSH-SF standard used for TRIR and LTIFR. Many UAE main contractors report on a 1,000,000-hour base for LTIFR benchmarking. The calculator lets you toggle between the two without re-entering data.

What counts as a recordable incident?

Any work-related injury or illness resulting in death, days away from work, restricted work, transfer to another job, medical treatment beyond first aid, loss of consciousness, or a significant diagnosed condition. First aid alone is not recordable.

How do I calculate man-hours for the period?

Add the total hours worked by all employees and contractors on site during the reporting period. Include overtime; exclude leave, sickness and public holidays.

Is the calculator data stored anywhere?
