Semco: 5.4 TCR = 164% of Tanks, storage, plastics or fiberglass, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Semco safety composite

Semco scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 21%), 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).
