Hi,
I have been asked to calculate the incidence rate for 2005 and 2006 for our company and I'm not sure what I'm doing! So far I have used the calculation;
incidence rate = number of accidents x 1000 / number of people employed
Please could someone give me some advice on whether this is correct or not and if I need to do another calculation. We are a medium sized company with approx 300 employees and we had 45 accidents in 2005 and 30 in 2006.
Any help would be appreciated!
Thanks,
K

That is a correct formula for accidents per 1000 personnel. We use it here in the MOD.
Good luck

Thanks very much.
This might sounds like a silly question, but do I use this calculation for 300 employees?
Thanks again,
K

My advice is to return to your customer & seek advice on exactly what equation or incidence rates they require.
Here are two other commonly used rates:
Incident rate = (number of accidents * 100,000) / man-hours worked
This is commonly used in the UK. Whereas American based companies prefer to use:
Incident rate = (number of accidents * 200,000) / man-hours worked.
The results of these differ by a factor of 2 !!
Also you need to ensure that you are clear in your definition of a accident - this could be "RIDDOR reportable cases", "OSHA reportable cases" (USA) or "days away from work cases", or "days away from work" - each will give you different figures and may help to show how good. or bad you are (there are lies, damned lies & statistics).
It seems that you can show a marked improvement on a year by year basis - so that is good, but if you choose the wrong rates and you are competing against a sister plant or another business based competitor, then it is crucial that you all play to the same rules.
All the best

Your calculation is correct. However, what are you trying to benchmark against? If you are just calculating the incident rate (IR) for internal comparison you could use any suitable calculation.
My organisation uses IR per 100 employees for external reporting because this is the IR used by the rest of our industry. This allows us to benchmark our performance against similar operations. National stats are calculated as IR per 100,000 workers.
Internally, we use an incident rate based on the number of hours worked. This allows us to monitor the IR across years, regardless of how much overtime and additional work is carried out in the year.
I also calculate the IR for each employee group. i.e. office workers, engineering. This can be useful to identify work areas that may need additional training or supervision. In this example the office staff had 6 accidents but have 50 in the employee group, this gives a group incident rate of 12 per 100 employees (6*100/50). The engineering department had 3 accidents with a staff of 6. IR 50 per 100 employees (3*100/6).
These are just examples, you can create incident rates against almost any criteria you want. A simple spreadsheet will do the job for you.
What ever you decide to benchmark against make sure that the figures generated are actually useful and help you identify areas to be targeted.
E-mail me direct if you would like an .xls example of the calculations.

Hi again,
I now need to calculate the incidence rate in "rate per million hours" - does anyone out there know how to do this?
Many thanks,
Kerri

We calculate the rate per million hours as:
(No. of incidents in period x 1,000,000)/no. of hours worked.
The hours worked is the number of employees in the period x the hours per worker per day x the number of days worked in the period.
These figures will vary over the period. An alternative to adding up every hour worked by every worker is to use averages.
