The verdict

St Clair Plant runs at 41% of its industry's injury rate - far safer than the typical industry workplace, earning a grade A.

St Clair Plant: 2.2 TCR = 41% of industry BLS 5.4 · 6y Form 300A (see methodology below)

St Clair Plant safety composite

St Clair Plant scores strongest on dart rate (safer than 87% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
