The verdict

M-8 runs at 158% of its industry's injury rate - more dangerous than the typical Bridge, tunnel, and highway operations workplace, earning a grade D.

M-8: 7.1 TCR = 158% of Bridge, tunnel, and highway operations BLS 4.5 · 5y Form 300A (see methodology below)

M-8 safety composite

M-8 scores strongest on dart rate (safer than 82% of same-industry peers) and weakest on total case rate (tcr) (safer than 26%), 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).

M-8 has fewer employees than the Bridge, tunnel, and highway operations median and a higher injury rate than the industry's median TCR of 4.4. 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.
