The verdict

Designed Metal Connections runs at 24% of its industry's injury rate - far safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade A.

Designed Metal Connections: 0.8 TCR = 24% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Designed Metal Connections safety composite

Designed Metal Connections scores strongest on total case rate (tcr) (safer than 77% of same-industry peers) and weakest on dart rate (safer than 43%), 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).

Grade A

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #21 safest of 104 Aircraft assemblies, subassemb employers in California.

Designed Metal Connections (396 employees, TCR 0.8) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Designed Metal Connections has more employees than the Aircraft assemblies, subassemblies, and median and a lower 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.
