The verdict

Corporate runs at 75% of its industry's injury rate - safer than the typical Grading construction sites workplace, earning a grade B.

Corporate: 2.1 TCR = 75% of Grading construction sites BLS 2.8 · 5y Form 300A (see methodology below)

Corporate safety composite

Corporate scores strongest on total case rate (tcr) (safer than 57% of same-industry peers) and weakest on dart rate (safer than 44%), 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).
