The verdict

Circor Aerospace & Defense runs at 14% of its industry's injury rate - far safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade A.

Circor Aerospace & Defense: 0.5 TCR = 14% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 6y Form 300A (see methodology below)

Circor Aerospace & Defense safety composite

Circor Aerospace & Defense scores strongest on total case rate (tcr) (safer than 88% 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).

Circor Aerospace & Defense (237 employees, TCR 0.5) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Circor Aerospace & Defense 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.
