The verdict

Centennial - ARA runs at 11% of its industry's injury rate - far safer than the typical Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing workplace, earning a grade A.

Centennial - ARA: 0.4 TCR = 11% of Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Centennial - ARA safety composite

Centennial - ARA scores strongest on dart rate (safer than 75% 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).
