The verdict

Miller Bros runs at 9% of its industry's injury rate - far safer than the typical Transmission and distribution line construction workplace, earning a grade A.

Miller Bros: 0.3 TCR = 9% of Transmission and distribution line construction BLS 2.8 · 3y Form 300A (see methodology below)

Miller Bros safety composite

Miller Bros scores strongest on total case rate (tcr) (safer than 95% of same-industry peers) and weakest on dart rate (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).
