The verdict

Grover Corporation runs at 40% of its industry's injury rate - far safer than the typical Gasoline engine parts, mechanical, automotive and truck, manufacturing workplace, earning a grade A.

Grover Corporation: 2.2 TCR = 40% of Gasoline engine parts, mechanical, automotive and truck, manufacturing BLS 5.4 · 3y Form 300A (see methodology below)

Grover Corporation safety composite

Grover Corporation scores strongest on total case rate (tcr) (safer than 66% of same-industry peers) and weakest on dart rate (safer than 15%), 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).
