Those who've been around safety (and particularly safety differently) long enough, know that LTI (Lost Time Injuries) is a lousy safety measure. LTI, after all, was once instituted as a productivity measure, not a safety measure. But LTI is actually quite a silly measure too. This blog shows just how silly it gets, and how foolish (or statistically meaningless) any claims about LTI reduction really are.
