The verdict

Shur-Lok Co. runs at 34% of its industry's injury rate - far safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade A.

Shur-Lok Co.: 1.1 TCR = 34% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Shur-Lok Co. safety composite

Shur-Lok Co. scores strongest on total case rate (tcr) (safer than 69% 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).
