How are these worked out? Is it accident/hours worked X 10'000.

Thanks

Sorry AFR's should be x 100,000 not 10k

I suggest it's much easier for a non-specialist to understand if you quote rates per 100 persons per year. Most people know what 100 people look like, but havn't a clue about hours.

HSE quote national rates per 100,000 people, which is also far too large a group for anyone to visualise - but you'll note that the resulting rates are ~500-5000 ish, i.e. divide by 1000 and you get the number of injuries per year per 100 people as 0.5-5, which all can visualise (and decide whether it seems acceptable, or not).

Incidentally, 100 people work about 200,000 hours per year (but few organisations record actual hours worked in today's world) and the US AFR rate is per 200,000 not the 100,000 traditionally used in UK; many global organisations use the US calculation. All this is FAR too involved for the average line manager to think about - so some of us in IOSH have been working for a while to get the "per 100 people per year" approach used more widely. What is the point of OSH professionals generating results data that means nothing to the average punter? - it just confirms to him/her that we don't live in the real world!

I like the reasoning Ian, it has caused me problems in the past too.

We have discussed it and similar before, see this thread, which I still refer too:
