The verdict

Coorstek runs at 34% of its industry's injury rate - far safer than the typical Advanced/technical ceramic product manufacturing workplace, earning a grade A.

Coorstek: 1.1 TCR = 34% of Advanced/technical ceramic product manufacturing BLS 3.3 · 6y Form 300A (see methodology below)

Coorstek safety composite

Coorstek scores strongest on total case rate (tcr) (safer than 88% 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).
