The verdict

RSA Engineered Products CA runs at 144% of its industry's injury rate - more dangerous than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade D.

RSA Engineered Products CA: 4.8 TCR = 144% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

RSA Engineered Products CA safety composite

RSA Engineered Products CA scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 8%), 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 RSA Engineered Products CA falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 14% of graded establishments in this industry, whose median TCR is 1.9.

Grade D

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #84 safest of 104 Aircraft assemblies, subassemb employers in California.

RSA Engineered Products CA (83 employees, TCR 4.8) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

RSA Engineered Products CA 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.
