The verdict

Holmberg Mechanical runs at 65% of its industry's injury rate - safer than the typical Mechanical contractors workplace, earning a grade B.

Holmberg Mechanical: 1.8 TCR = 65% of Mechanical contractors BLS 2.8 · 3y Form 300A (see methodology below)

Holmberg Mechanical safety composite

Holmberg Mechanical scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
