Lost Time Injury Frequency Rate

on . Posted in Safety Engineering

Lost time injury frequency rate, abbreviated as LTIFR, is the number of lost time injuries that have occured within a given accounting period, relative to the total number of hours worked in that period.


Lost Time Injury Frequency Rate formula

\(\large{ LTIFR =  \frac{ TNLTI \; 200,000}{ TNE }  }\)   


\(\large{ LTIFR }\) = lost time injury frequency rate

\(\large{ TNLTI }\) = total number of lost time incidents

\(\large{ TNE }\) = total number of employees
