The verdict

Main Plant runs at 70% of its industry's injury rate - safer than the typical Machine shops workplace, earning a grade B.

Main Plant: 2.3 TCR = 70% of Machine shops BLS 3.3 · 3y Form 300A (see methodology below)

Main Plant safety composite

Main Plant scores strongest on dart rate (safer than 75% 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).
