Heritage Lab: 2.0 TCR = 60% of Dental laboratories BLS 3.3 · 6y Form 300A (see methodology below)

Heritage Lab safety composite

Heritage Lab scores strongest on dart rate (safer than 72% 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).
