The verdict

Main runs at 104% of its industry's injury rate - about level with the typical Machine shops workplace, earning a grade C.

Main: 3.4 TCR = 104% of Machine shops BLS 3.3 · 7y Form 300A (see methodology below)

Main safety composite

Main scores strongest on total case rate (tcr) (safer than 51% of same-industry peers) and weakest on dart rate (safer than 19%), 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).
