Leach International Corporation safety composite

Leach International Corporation scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 0%), blended into one 0-100 breakdown against same-industry peers.

This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
