The verdict

Core-Mark ADC runs at 119% of its industry's injury rate - about level with the typical industry workplace, earning a grade C.

Core-Mark ADC: 2.6 TCR = 119% of industry BLS 2.2 · 2y Form 300A (see methodology below)

Core-Mark ADC safety composite

Core-Mark ADC scores strongest on total case rate (tcr) (safer than 82% 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).
