The verdict

Mitchell Materials runs at 69% of its industry's injury rate - safer than the typical Highway construction workplace, earning a grade B.

Mitchell Materials: 1.9 TCR = 69% of Highway construction BLS 2.8 · 2y Form 300A (see methodology below)

Mitchell Materials safety composite

Mitchell Materials scores strongest on total case rate (tcr) (safer than 67% of same-industry peers) and weakest on dart rate (safer than 21%), 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).
