The verdict

Main Office runs at 66% of its industry's injury rate - safer than the typical Electric contracting workplace, earning a grade B.

Main Office: 1.9 TCR = 66% of Electric contracting BLS 2.8 · 7y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on total case rate (tcr) (safer than 61% of same-industry peers) and weakest on dart rate (safer than 45%), 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).
