The verdict

Natrol Industries LLC runs at 21% of its industry's injury rate - far safer than the typical Vitamin preparations manufacturing workplace, earning a grade A.

Natrol Industries LLC: 0.7 TCR = 21% of Vitamin preparations manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Natrol Industries LLC safety composite

Natrol Industries LLC scores strongest on total case rate (tcr) (safer than 80% of same-industry peers) and weakest on dart rate (safer than 42%), 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).
