The frequency rate shall be calculated both for
lost time injury and reportable lost time injury as follows:
FA= Number of lost time injury x 1 000 000/Man-hours worked
FB =Number of reportable lost time injury x 1 000 000/ Man-hours worked
NOTE 1 - If the injury does not cause loss of time in the period in which it occurs
but in a subsequent period, the injury should be included in the frequency rate of the
period in which the loss of time begins.
NOTE 2 - If an injury causes intermittent loss of time, it should only be included
in the frequency rate once, that is, when the first loss of time occurs.
NOTE 3 - Since frequency rate & is based on the lost time injuriestreportable to
the statutory authorities, it may be used for official purposes only. In all other cases,
frequency rate FA should be used for comparison purposes.

The severity rate shall be calculated from mandays
lost both of lost time injury and reportable lost time injury as
follows:
SA = Man-days lost due to lost time injury x 1 000 000/Man-hours worked
SB = Man-days lost due to reportable lost time injury x 1 000 000/ Man-hours worked
NOTE - Since severity rate &j is based on the lost time injuries reportable to the
statutory authorities, it should be used for official purposes only. In all other cases
severity rate SA should be used for comparison purposes.

Dear Mr. Ahammad
Please go through the Appendix A of IS 3786-1983. It's clearly mentioning the answer to your query... Fatality is not treated as LTI... But in many situation 6000 man days lost is considered for the calculation LTI as same as in the case of fatality...
