LTI severity rating Hi Jan, personally I think Safeguard should ban conversations that promote the use of LTIs, TRIFR etc :-)
Seriously though, I don't think your approach is the right thing to do. Rather than focusing on the little and often injuries you should focus on the potentially major but infrequent events. Little and often is mostly within an organization's risk tolerance level, while major and infrequent isn't. The approach you suggest held us back for years until we finally convinced the higher-ups otherwise. Yes we did reduce many of our lesser injuries which is of course a good thing - you don't ignore these - but it did noting for our serious incidents which seriously hurt or were fatal.
A focus on critical risks, as Alex says, is essential.
