The verdict

Main Office runs at 70% of its industry's injury rate - safer than the typical Excavating, earthmoving, or land clearing contractors workplace, earning a grade B.

Main Office: 2.0 TCR = 70% of Excavating, earthmoving, or land clearing contractors BLS 2.8 · 8y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on dart rate (safer than 77% 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).
