The verdict

Space-Lok runs at 19% of its industry's injury rate - far safer than the typical Bolts, metal, manufacturing workplace, earning a grade A.

Space-Lok: 0.6 TCR = 19% of Bolts, metal, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Space-Lok safety composite

Space-Lok scores strongest on total case rate (tcr) (safer than 96% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
