How to Calculate LTIFR and Other Health and Safety Indicators

Knowing how to calculate LTIFR and different security indicators is a vital ability to have in case you work within the well being and security subject. Despite the truth that these indicators do not reveal an excessive amount of helpful info managers love them and will insist on figuring out what they’re. They will use them to measure inside well being and security efficiency and to evaluate you are firm’s efficiency with different firms. These should not troublesome to calculate and this may be made even simpler in case you use an expansion sheet.

Health and Safety Indicators

Broadly talking, widespread well being and security indicators will be divided into two – frequency charges and incidence charges. So what is the distinction?

A frequency charge is an expression of what number of occasions occurred over a given time frame by a standardised variety of hours labored. An incidence charge is the variety of occasions that occurred over a given interval time by a standardised variety of staff (normally decrease than the standardised variety of hours). For instance, an LTIFR which stands for Lost Time Injury Frequency Rate, is the variety of Lost Time Injuries (LTI) that occurred over a interval time per 1 000 000 or 100 000 or another variety of hours labored in that interval. This may very well be over a month or 1 / 4 or a yr relying on the reporting necessities of what you are promoting. To convert this to an incidence charge simply substitute the variety of staff for the variety of hours.

Loads of issues are introduced on this method. As effectively as misplaced time accidents there are Medical Treatment Injuries (MTI) one other is critical accidents which are sometimes categorized as LTIs plus MTIs. A slight variation is the severity charge which is normally a measure of the period of time misplaced due to work associated harm by some standardised determine that’s used to point out the severity of accidents.

Calculating Frequency Rates

The system to calculate these indicators is absolutely quite simple. Let’s say we wish the variety of misplaced time accidents per 1 000 000 hours labored for the final yr. You want to get two items of data – the variety of LTIs that occurred within the final yr and the variety of hours labored within the final yr. You might most likely get the variety of LTIs out of your staff compensation claims supervisor or insurance coverage firm and your payroll part ought to have the ability to let you know the variety of hours labored over the interval.

Multiply the variety of LTIs by 1 000 000 and divide the outcome by the variety of hours labored and there you’ve gotten it – the LTIFR. To present it utilizing numbers. Say there have been 7 LTIs prior to now yr and 2 451 679 hours labored. So, 7 X 1 000 000 = 7 000 000. Divide that by 2 451 679 and you get 2.86 – go on, seize your calculator and strive for your self.

What does that imply? It implies that this enterprise skilled 2.86 LTIs for each 1 000 000 hours labored over the previous yr.

Calculating Incidence Rates

Now, to calculate the LTIIR (Lost Time Injury Incidence Rate) which is the variety of LTIs per 100 (or no matter determine you need) staff we simply substitute the variety of staff for the variety of hours and multiply the variety of LTIs by the standardizing issue which is 100.

So say this legendary enterprise had 791 staff, we get 7 X 100 = 700. Divide this by the variety of staff – 791 – and we get 0.88. So for each 100 staff this agency skilled 0.88 LTIs.

Calculating Severity Rates

Finally the severity charge. Depending on how that is expressed you’ll need a minimum of the data from above and the variety of work days misplaced over the yr. Say its 73. Most typically the severity charge is expressed as a mean by merely dividing the variety of days misplaced by the variety of LTIs. So, utilizing the figures we’ve got we get 73 divided by 7 which supplies 10.43. That is, on common every LTI will end in 10.5 days off work. It will be transformed to a frequency or incidence charge by multiplying the outcome by a standardizing issue. This, in fact will enhance the outcome which is why you do not see it fairly often – who needs a severity charge of 104 days off per 100 LTIs?

So there you’ve gotten it. Not very exhausting and if you realize even somewhat bit about spreadsheets you may simply insert the formulation into particular cells to calculate these indicators robotically.
