The verdict

L3Harris runs at 28% of its industry's injury rate - far safer than the typical Night vision optical device manufacturing workplace, earning a grade A.

L3Harris: 0.9 TCR = 28% of Night vision optical device manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

L3Harris safety composite

L3Harris scores strongest on total case rate (tcr) (safer than 74% of same-industry peers) and weakest on dart rate (safer than 42%), 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).
