The verdict

Corporate runs at 584% of its industry's injury rate - far more dangerous than the typical Clay construction materials (except refractory) merchant wholesalers workplace, earning a grade F.

Corporate: 12.8 TCR = 584% of Clay construction materials (except refractory) merchant wholesalers BLS 2.2 · 2y Form 300A (see methodology below)

Corporate safety composite

Corporate scores strongest on dart rate (safer than 74% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).
