The verdict

Wenzlau Engineering runs at 269% of its industry's injury rate - far more dangerous than the typical Motor generator sets (except automotive, turbine generator sets) manufacturing workplace, earning a grade F.

Wenzlau Engineering: 8.9 TCR = 269% of Motor generator sets (except automotive, turbine generator sets) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Wenzlau Engineering safety composite

Wenzlau Engineering scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 1%), 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).
