Calculating An Injury Frequency Rate

Hello everyone, I believe I have this down but wanted confirmation from the experts. Seems simple enough.

Basically, I want to calculate the "Total Recordable Injury Frequency Rate (TRIFR)" of a company per 200,000 work hours.

Assuming 1 employee= 2000 hours worked

What would be the TRIFR per 200,000 work hours if the company had the following.

2016: 2422 employees; 40 accidents
2015: 2316 employees; 40 accidents
2014: 2197 employees; 29 Accidents

Thank you all

rate per 200000 hours, when 1 employee works 2000 hours, is equivalent to rate per 100 employees.

So divide the number of employees by 100 to get the number of 200 khrs and just read off the number of accidents for that period.

For example in 2016

2422 employees is equivalent to 242.2 200 khrs.

So we have 40 accidents per 242.2 200 khrs = 40/242.2 = 0.165 accidents per 200 khr.

I'm sure you can complete the other years.

Thanks for the quick reply


Wouldn't 2422 employees be equivalent to 24.2 not 244.2?

2422 /100.

Or do we divide by 10 and not 100?

It's ok, I appreciate the help. It's the same figure I got, only I did it way longer jajaja. Thank you once again.
