The verdict

Mueller runs at 124% of its industry's injury rate - more dangerous than the typical Iron foundries workplace, earning a grade D.

Mueller: 4.1 TCR = 124% of Iron foundries BLS 3.3 · 2y Form 300A (see methodology below)

Mueller safety composite

Mueller scores strongest on total case rate (tcr) (safer than 76% of same-industry peers) and weakest on fatalities (safer than 52%), 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).
