The verdict

Building 4 runs at 246% of its industry's injury rate - far more dangerous than the typical Research and Development in the Physical~ Engineering and Life Sciences workplace, earning a grade F.

Building 4: 1.2 TCR = 246% of Research and Development in the Physical~ Engineering and Life Sciences BLS 0.5 · 2y Form 300A (see methodology below)

Building 4 safety composite

Building 4 scores strongest on dart rate (safer than 68% of same-industry peers) and weakest on total case rate (tcr) (safer than 40%), 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).

Grade F

More dangerous than peersSafer than peers

Narrower to Michigan alone (the establishments it most directly competes with for workers and contracts): ranked #3 safest of 4 Research and Development in th employers in Michigan.

Building 4 (137 employees, TCR 1.2) among 23 same-industry peers, split at the industry median of 232 employees and a TCR of 0.9

Building 4 has fewer employees than the Research and Development in the Physical median and a higher injury rate than the industry's median TCR of 0.9. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
