Could some one clarify the formula for calculating accident frequency rates

number of accidents / hours worked x 100,000


Does the hours worked mean for each employee added together or the number of working hours the company operates annually?

Also can anyone tell me where i may find statistics of accident frequency rates for the care industry which i can benchmark my calculations against.

Kind regards

Its a total of man hours worked therefore a sum of total employee hours. As for the benchmarking info, im looking myself. As it seems are other people on this forum.

Hi Guys
Quite a lot of the bigger [multinationals] companies include that sort of info in their annual reports especially in the pharmaceitucal industry, other that that how about the Chamber of Commerce, British Safety Council, ROSPA, TUC?

Accident rate is calculated by the following

Number of injuries X 1000
Average number of employees during the period.

Frequency rate is calculated by the following:-

Number of injuries X 1000
Total number of employed during the period.

Frequency rate is calculated by the following:-

1 x 1000 = 55.55
18

Accident rate is calculated by the following

Number of injuries X 1000
Average umber of employees during the period.

1 x 1000 = 55
18

For most industries we have always used the following rates:

No. of Accidents x 100,000/ Average hours worked for the period.

This is the Frequency Rate and the resulting figure is how many accidents an employee can expect in a working lifetime (that is what the 100,000 represents).

No. of Accidents x 1000/ Average number of people employed.

This is the Incident Rate and the resulting figure shows how many people per one thousand (if you did employ a thousand) would be injured).

But as usual different clients have their own systems for whatever reason - ask them to explain the meaning behind the calculation. As long as you can explain yours you should be ok.

My pet hate.
The dreaded accident rate, incident rate, Lost time accident rate, frequency rate etc. etc.
Our company operate these Stats world wide and they mean nothing. They can all be fiddled and are.
Take 2 companies employing the same number of persons. Each have one accident resulting in the same accident rate. One accident resulted in a fatality, the other a 3-day absence.
What do the stats tell you. Naff all.
The only one that comes close is the severity rate, as this consideres time lost.
I'll get off my soap box now.
Prevent the accidents, that's the way.

Barry,

how many days do you count for a fatality ?

And a number of multi-national companies use the OSHA rate which is LTI per 200 000 exposure hours. I like it because it comes out very close to a percentage - If you have an OSHA rate of 1 you are injuring roughly 1% of your employees.
