1/1

A lost time injury or disease (LTI):

Is a work-related injury or disease that has caused a worker to be absent from his or her regular work following the day that the injury or awareness of the disease occurred.

To calculate the lost time Injury Frequency (LTIF):

1. Sum all the lost time accidents cases that you have during that period you want to calculate the LTIF if the you are preparing a monthly report you have to get the total man hours worked for that month(exposure hours) & if you are preparing 1 year report ( through out 2011 for example) the man hours will be the total of LTI through that year & the total man hours through that year for example if your = 6 LTI cases in March 2011 & your man hours is 765,462 man hours

2. use this formula:

LTI Freq. Rate = Total LTI X 1,000,000 / Total Man hours

LTI Freq. Rate = Total LTI (6) X 1,000,000 / Total Man hours (765,462) = 7.8

( LTIF)

3. TRCF :Total Recordable Cases Frequency

TRCF = Number of LTI + MTC + RWC X 1,000,000 / Man hours for the month

(LTI) Lost Time Injuries

(MTC) Medical Treatment Cases

(RWC) Restricted Work Cases
