This page helps you calculate and compare work health and safety performance in your organisation with the broader industry
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.
To make it easy to interpret, LTIFRs are reported as the number of lost-time injuries per million hours worked.
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
