The verdict

Mack Engineering Corp runs at 62% of its industry's injury rate - safer than the typical Precision turned product manufacturing workplace, earning a grade B.

Mack Engineering Corp: 2.0 TCR = 62% of Precision turned product manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Mack Engineering Corp safety composite

Mack Engineering Corp scores strongest on total case rate (tcr) (safer than 79% of same-industry peers) and weakest on dart rate (safer than 7%), 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).

Mack Engineering Corp (24 employees, TCR 2.0) among 29 same-industry peers, split at the industry median of 61 employees and a TCR of 3.6

Mack Engineering Corp has fewer employees than the Precision turned product manufacturing median and a lower injury rate than the industry's median TCR of 3.6.
