The verdict

Hygrade Precision Technologies runs at 361% of its industry's injury rate - far more dangerous than the typical Machine shops workplace, earning a grade F.

Hygrade Precision Technologies: 11.9 TCR = 361% of Machine shops BLS 3.3 · 5y Form 300A (see methodology below)

Hygrade Precision Technologies safety composite

Hygrade Precision Technologies scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

Hygrade Precision Technologies has fewer employees than the Machine shops median and a higher injury rate than the industry's median TCR of 3.5. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
