The verdict

Maren Engineering runs at 198% of its industry's injury rate - more dangerous than the typical Pipe, fabricated metal plate, manufacturing workplace, earning a grade D.

Maren Engineering: 6.5 TCR = 198% of Pipe, fabricated metal plate, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Maren Engineering safety composite

Maren Engineering scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 28%), 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).
