The verdict

Memc Soi runs at 23% of its industry's injury rate - far safer than the typical Silicon wafers, chemically doped, manufacturing workplace, earning a grade A.

Memc Soi: 0.8 TCR = 23% of Silicon wafers, chemically doped, manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Memc Soi safety composite

Memc Soi scores strongest on total case rate (tcr) (safer than 61% of same-industry peers) and weakest on dart rate (safer than 37%), 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).
