Isolatek-Houston: 4.0 TCR = 120% of Vermiculite, exfoliated, manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Isolatek-Houston safety composite

Isolatek-Houston scores strongest on dart rate (safer than 76% of same-industry peers) and weakest on total case rate (tcr) (safer than 21%), 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).
