Sekisui Diagnostics runs at 49% of its industry's injury rate - far safer than the typical Blood derivative in-vitro diagnostic substances manufacturing workplace, earning a grade A.

Sekisui Diagnostics: 1.6 TCR = 49% of Blood derivative in-vitro diagnostic substances manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Sekisui Diagnostics safety composite

Sekisui Diagnostics scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 30%), 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).
