The verdict

American Gypsum runs at 35% of its industry's injury rate - far safer than the typical Wallboard, gypsum, manufacturing workplace, earning a grade A.

American Gypsum: 1.1 TCR = 35% of Wallboard, gypsum, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

American Gypsum safety composite

American Gypsum scores strongest on total case rate (tcr) (safer than 89% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
