The verdict

RockSol runs at 102% of its industry's injury rate - about level with the typical Engineering services workplace, earning a grade C.

RockSol: 0.5 TCR = 102% of Engineering services BLS 0.5 · 2y Form 300A (see methodology below)

RockSol safety composite

RockSol scores strongest on total case rate (tcr) (safer than 67% of same-industry peers) and weakest on dart rate (safer than 28%), 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).
