The verdict

M.S Aerospace runs at 172% of its industry's injury rate - more dangerous than the typical Bolts, metal, manufacturing workplace, earning a grade D.

M.S Aerospace: 5.7 TCR = 172% of Bolts, metal, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

M.S Aerospace safety composite

M.S Aerospace scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 24%), 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).
