The verdict

Ssl Soi runs at 30% of its industry's injury rate - far safer than the typical Silicon wafers, chemically doped, manufacturing workplace, earning a grade A.

Ssl Soi: 1.0 TCR = 30% of Silicon wafers, chemically doped, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Ssl Soi safety composite

Ssl Soi scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 40%), 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).
