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
