The verdict

Michigan Office runs at 19% of its industry's injury rate - far safer than the typical Wiring harness and ignition sets for internal combustion engines manufacturing workplace, earning a grade A.

Michigan Office: 1.0 TCR = 19% of Wiring harness and ignition sets for internal combustion engines manufacturing BLS 5.4 · 9y Form 300A (see methodology below)

Michigan Office safety composite

Michigan Office scores strongest on dart rate (safer than 84% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
