The verdict

Ironstone runs at 176% of its industry's injury rate - more dangerous than the typical Wines manufacturing workplace, earning a grade D.

Ironstone: 5.8 TCR = 176% of Wines manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Ironstone safety composite

Ironstone scores strongest on dart rate (safer than 82% of same-industry peers) and weakest on total case rate (tcr) (safer than 38%), 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).
