The verdict

Am-Ex 709 runs at 162% of its industry's injury rate - more dangerous than the typical Heat exchangers manufacturing workplace, earning a grade D.

Am-Ex 709: 5.3 TCR = 162% of Heat exchangers manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Am-Ex 709 safety composite

Am-Ex 709 scores strongest on dart rate (safer than 79% of same-industry peers) and weakest on total case rate (tcr) (safer than 28%), 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).
