The verdict

Main Office runs at 61% of its industry's injury rate - safer than the typical Ceramic tile installation workplace, earning a grade B.

Main Office: 1.7 TCR = 61% of Ceramic tile installation BLS 2.8 · 3y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on total case rate (tcr) (safer than 78% of same-industry peers) and weakest on dart rate (safer than 38%), 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).
