Hello
I work for a large manufacturing company and part of my remit is to provide accident statistics on a monthly basis.
The type of stats that I provide are along these lines


Total incidents ( including near misses and plant damage)
These are split into body part affected and injury type

BODY PART AFFECTED
Total near misses
total head injuries
total eye injuries
total torso injuries
total back injuries
total arm injuries
total hand injuries
total leg injuries
total foot injuries

INJURY TYPE
Total fractures
total bruises / strains and sprains
total cuts / puncture wounds
total burns (including chemical)
total loss of consciousness
total foreign bodies
total electric shocks
total gassing / poisoning
total other eg dermatitus

Most of these can be displayed graphically eg pie charts etc

In addition I report the Incident Frequency Rate (IFR) which is derived from the folowing formula

IFR = Total accidents X 1000000 / Total hours worked

Also reported is the Severity Rate (SR) which is derived from the following formula

SR = Total days lost due to accidents X 1000 / total hours worked.

Connected to the severity rate is the number of RIDDORs

Quite a lot to trawl through but I hope you found it useful

It's the total hours of all employees. The formula is a standard one used across many industries and is used to give an idea of how you would compare to other similar companies. I have no idea why 1000000 is used as opposed to some other figure though

That's an interesting link, i've put it on my favourites list for now.

The million hours rate is legally required for injury rate reporting in most european countries.

200 000 hours rates are required under US osha rules and, as the article says, are closely equivalent to a percentage of employees being injured (an OSHA recordable rate of 1 indicates that 1% of employees have had a "recordable" injury.

Because of different working times across europe, the "million hour" rate is not so easy to visualise but, roughly, 1 LTI per million hours means 1 injury to about 600 man-years.

Some unfortunates I have encountered have to keep three sets of stats : european, UK and US, and according to three definitions of "injuries"

I have never heard of anyone using 2 000 000 hours for safety statistics. one million is hard enough to justify.
