The verdict

Promega Biosciences LLC runs at 32% of its industry's injury rate - far safer than the typical In-vitro diagnostic substances manufacturing workplace, earning a grade A.

Promega Biosciences LLC: 1.0 TCR = 32% of In-vitro diagnostic substances manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Promega Biosciences LLC safety composite

Promega Biosciences LLC scores strongest on total case rate (tcr) (safer than 66% of same-industry peers) and weakest on dart rate (safer than 32%), 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).

Promega Biosciences LLC has fewer employees than the In-vitro diagnostic substances manufactu median and a lower injury rate than the industry's median TCR of 1.4. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
