To calculate and benchmark your performance, use the lost time injury frequency rate (LTIFR). The LTIFR is the average number of lost-time injuries in each industry in Australia each year.
Lost time injury frequency rate (LTIFR)
The LTIFR measures the number of lost-time injuries per million hours worked during a single financial year.
It doesn’t matter how serious the injury was, as long as it involved some time off work.
The number of lost-time injuries per hour worked is always a very small number.
What you need to know to calculate your LTIFR
To calculate your LTIFR, you will need to know:
- the relevant industry for your organisation according to the Australian and New Zealand Standard Industrial Classification (ANZSIC), 2006
- the number of lost time injuries that occurred in your organisation during a single financial year
- the total number of hours worked by all employees of your organisation during the same period.
A lost time injury is any injury that results in a fatality, permanent disability or time lost from work.
It could be as little as one day or shift.
You should not include pre-existing conditions that weren’t sustained during the reporting period.
Calculating your LTIFR
The formula to calculate an LTIFR is:
( Number of lost time injuries in accounting period ) ------------------------------------------------------- × 1,000,000 ( Total hours worked in accounting period )
In 2011, a building construction company had 2 people injured at work. One went to hospital for one week and the other was away for one full day.
The company employs 375 staff, some of whom work part-time hours. The total hours worked in 2011 for all employees was 700,500.
To calculate the company’s LTIFR:
- there are 2 people who have lost time from work for one shift or more
- they worked 700,500 hours over the period
- use the formula: (2 / 700,500) x 1,000,000
- this equals a rate of 2.86, which is lower than the building construction industry rate of 5.6.
Number of lost time injuries during the year: 2
Hours worked during the year: 700,500
LTIFR = 2.86
Industry: Building construction (ANZSIC level 1.2)
Industry LTIFR = 5.6
