The verdict

Mar-K runs at 68% of its industry's injury rate - safer than the typical Automobile hardware, metal, manufacturing workplace, earning a grade B.

Mar-K: 2.2 TCR = 68% of Automobile hardware, metal, manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

Mar-K safety composite

Mar-K scores strongest on dart rate (safer than 84% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
