The verdict

Lamsco runs at 233% of its industry's injury rate - far more dangerous than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade F.

Lamsco: 7.7 TCR = 233% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Lamsco safety composite

Lamsco scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

Lamsco has more employees than the Aircraft assemblies, subassemblies, and median and a higher injury rate than the industry's median TCR of 1.9. 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.
