The verdict

NDX H and O runs at 218% of its industry's injury rate - far more dangerous than the typical Dental Laboratories workplace, earning a grade F.

NDX H and O: 7.2 TCR = 218% of Dental Laboratories BLS 3.3 · 3y Form 300A (see methodology below)

NDX H and O safety composite

NDX H and O scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).
