The verdict

Entegris runs at 56% of its industry's injury rate - safer than the typical Accelerators (i.e., basic synthetic chemical) manufacturing workplace, earning a grade B.

Entegris: 1.8 TCR = 56% of Accelerators (i.e., basic synthetic chemical) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Entegris safety composite

Entegris scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on total case rate (tcr) (safer than 42%), 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).
