Posted By Peter Longworth 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

Posted By Peter Longworth 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

Posted By Merv Newman 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"

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