The verdict

Main Office runs at 281% of its industry's injury rate - far more dangerous than the typical Janitorial Services workplace, earning a grade F.

Main Office: 12.7 TCR = 281% of Janitorial Services BLS 4.5 · 3y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 2%), 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).
