The verdict

GKN Aerospace Chem-tronics runs at 109% of its industry's injury rate - about level with the typical Aircraft turbines manufacturing workplace, earning a grade C.

GKN Aerospace Chem-tronics: 3.6 TCR = 109% of Aircraft turbines manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

GKN Aerospace Chem-tronics safety composite

GKN Aerospace Chem-tronics scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 16%), 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 GKN Aerospace Chem-tronics falls in its industry

366 Aircraft turbines manufacturin establishments

Safer than 18% of graded establishments in this industry, whose median TCR is 1.6.

Grade C

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #9 safest of 13 Aircraft turbines manufacturin employers in California.

GKN Aerospace Chem-tronics (1,059 employees, TCR 3.6) among 29 same-industry peers, split at the industry median of 155 employees and a TCR of 1.6

GKN Aerospace Chem-tronics has more employees than the Aircraft turbines manufacturing median and a higher injury rate than the industry's median TCR of 1.6. 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.
