The verdict

Ab Sciex LLC runs at 32% of its industry's injury rate - far safer than the typical Mass spectroscopy instrumentation manufacturing workplace, earning a grade A.

Ab Sciex LLC: 1.1 TCR = 32% of Mass spectroscopy instrumentation manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Ab Sciex LLC safety composite

Ab Sciex LLC scores strongest on total case rate (tcr) (safer than 53% of same-industry peers) and weakest on dart rate (safer than 43%), 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).
