The verdict

HyAxiom Inc runs at 66% of its industry's injury rate - safer than the typical Electrochemical generators (i.e., fuel cells) manufacturing workplace, earning a grade B.

HyAxiom Inc: 2.2 TCR = 66% of Electrochemical generators (i.e., fuel cells) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

HyAxiom Inc safety composite

HyAxiom Inc scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 24%), 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).
