50 employees x 40 hours per week x 50 weeks a year.

It's related to the size of the organisation. Some use 100,000 some use 1,000,000 depending on the number of hours worked. To be honest it could be any figure at all because it is just a way of comparing data.
What it does is make the final figure easier to visualise. Otherwise you would finish up with accident frequency rates of something like 0.0000001 whereas 10 or 100 looks better.

It is a mulitplier used so that the accident rates are a number that you can comprehend and you're not detailing with rates of 0.000001 or 0.000017 etc etc.

You can use any number as the multiplier if you want but the most commonly used one is 100,000.

For example if you use 1000 you have calculated the rate per 1000 hours, if you use 1,000,000 you have calculated the rate per 1,000,000 hours. Depends on the size of the business really and what multiplier makes the stats easier.

Grumpy,

I seem to remember being told, when I did my ROSPA course in the late 80's, that it represented roughly the total number of working hours in a lifetime 40hours*50weeks*50years. But then I could never explain why the USA used 200,000
