Onamac Industries Inc safety composite

Onamac Industries Inc scores strongest on total case rate (tcr) (safer than 58% of same-industry peers) and weakest on dart rate (safer than 22%), 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).
