The verdict

L3Harris KEO runs at 11% of its industry's injury rate - far safer than the typical Search and detection systems and instruments manufacturing workplace, earning a grade A.

L3Harris KEO: 0.3 TCR = 11% of Search and detection systems and instruments manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

L3Harris KEO safety composite

L3Harris KEO scores strongest on total case rate (tcr) (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).
