The verdict

Transparency Division runs at 87% of its industry's injury rate - about level with the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade C.

Transparency Division: 2.9 TCR = 87% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Transparency Division safety composite

Transparency Division scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 31%), 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 C

More dangerous than peersSafer than peers

Narrower to Oklahoma alone (the establishments it most directly competes with for workers and contracts): ranked #28 safest of 31 Aircraft assemblies, subassemb employers in Oklahoma.

Transparency Division (175 employees, TCR 2.9) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Transparency Division 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.
