The verdict

Natoli Engineering runs at 68% of its industry's injury rate - safer than the typical Machine shops workplace, earning a grade B.

Natoli Engineering: 2.2 TCR = 68% of Machine shops BLS 3.3 · 2y Form 300A (see methodology below)

Natoli Engineering safety composite

Natoli Engineering scores strongest on total case rate (tcr) (safer than 69% of same-industry peers) and weakest on dart rate (safer than 43%), 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).
