The verdict

M&K Engineering Inc. runs at 110% of its industry's injury rate - about level with the typical Precision turned product manufacturing workplace, earning a grade C.

M&K Engineering Inc.: 3.6 TCR = 110% of Precision turned product manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

M&K Engineering Inc. safety composite

M&K Engineering Inc. scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 19%), 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).
