The verdict

QualiTau, Inc, runs at 17% of its industry's injury rate - far safer than the typical Semiconductor test equipment manufacturing workplace, earning a grade A.

QualiTau, Inc,: 0.6 TCR = 17% of Semiconductor test equipment manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

QualiTau, Inc, safety composite

QualiTau, Inc, scores strongest on total case rate (tcr) (safer than 72% of same-industry peers) and weakest on dart rate (safer than 19%), 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).
