The verdict

Warmelin Precision Products runs at 294% 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.

Warmelin Precision Products safety composite

Warmelin Precision Products scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 1%), 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).

Where Warmelin Precision Products falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 1% of graded establishments in this industry, whose median TCR is 1.9.

Grade F

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #101 safest of 104 Aircraft assemblies, subassemb employers in California.

Warmelin Precision Products (85 employees, TCR 9.7) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Warmelin Precision Products has fewer 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.
