Number of lost time incidents X 200,000.
Number of man hours worked.
calculation of lost time injury
Hi LTIR = No. of LTIs x 200000 --------------------------- Total manhours
Lost Time Injury Frequency Rate (LTIFR):A measure commonly used to report workplace safety performance which is calculated by dividing the number of LTIs by the total hours worked, multiplied by one million
periodic time is the reciprocal of frequency , so if the frequency is 4 then the periodic time is 1/4
injury time
Certainly medical treatment for an injury can be connected with an injury that involves lost time from work, but it depends on the nature of the injury and the kind of medical treatment that is required.
To calculate frequency from a wave diagram, count the number of complete cycles of the wave that occur within a period of time. Then, divide the number of cycles by the time period to determine the frequency in hertz (Hz). The formula for calculating frequency is: frequency = number of cycles / time period.
Number of lost time incidents X 200,000. Number of man hours worked.
Death $4,459,000Incapacitating injury $225,100Nonincapacitating evident injury $57,400Possible injury $27,200No injury $2,400
Count the number of events occurring during a time period. Then frequency = number of events/length of time period.
A lost time injury is one that results in your being unable to report to work the next day that would otherwise be a workday for you, or and injury that results in your being restricted in what you can do for a time, so you cannot perform all the regular aspects of your job.
