The verdict

S Diamond Steel runs at 134% of its industry's injury rate - more dangerous than the typical Structural steel, fabricated, manufacturing workplace, earning a grade D.

S Diamond Steel: 4.4 TCR = 134% of Structural steel, fabricated, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

S Diamond Steel safety composite

S Diamond Steel scores strongest on total case rate (tcr) (safer than 51% of same-industry peers) and weakest on dart rate (safer than 41%), 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).
