The verdict

Superior runs at 223% of its industry's injury rate - far more dangerous than the typical Dump trailer manufacturing workplace, earning a grade F.

Superior: 7.4 TCR = 223% of Dump trailer manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Superior safety composite

Superior scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 25%), 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).
