The verdict

Corporate Office runs at 2% of its industry's injury rate - far safer than the typical Nickel refining, primary workplace, earning a grade A.

Corporate Office: 0.1 TCR = 2% of Nickel refining, primary BLS 3.3 · 4y Form 300A (see methodology below)

Corporate Office safety composite

Corporate Office scores strongest on total case rate (tcr) (safer than 98% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
