The verdict

Hi-Tech Machining & Engineering, L.L.C. runs at 716% of its industry's injury rate - far more dangerous than the typical Mechanical engineering services workplace, earning a grade F.

Hi-Tech Machining & Engineering, L.L.C.: 3.6 TCR = 716% of Mechanical engineering services BLS 0.5 · 2y Form 300A (see methodology below)

Hi-Tech Machining & Engineering, L.L.C. safety composite

Hi-Tech Machining & Engineering, L.L.C. scores strongest on dart rate (safer than 70% of same-industry peers) and weakest on total case rate (tcr) (safer than 15%), 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).
