The verdict

Mertz runs at 250% of its industry's injury rate - far more dangerous than the typical Machine shops workplace, earning a grade F.

Mertz: 8.2 TCR = 250% of Machine shops BLS 3.3 · 7y Form 300A (see methodology below)

Mertz safety composite

Mertz scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 11%), 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).
