The verdict

AET runs at 681% of its industry's injury rate - far more dangerous than the typical Machine bases, metal, manufacturing workplace, earning a grade F.

AET: 22.5 TCR = 681% of Machine bases, metal, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

AET safety composite

AET scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 0%), 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).

AET (45 employees, TCR 22.5) among 29 same-industry peers, split at the industry median of 67 employees and a TCR of 4.5

AET has fewer employees than the Machine bases, metal, manufacturing median and a higher injury rate than the industry's median TCR of 4.5. 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.
