The verdict

L3Harris runs at 11% of its industry's injury rate - far safer than the typical Flight recorders (i.e., black boxes) manufacturing workplace, earning a grade A.

L3Harris: 0.4 TCR = 11% of Flight recorders (i.e., black boxes) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

L3Harris safety composite

L3Harris scores strongest on dart rate (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).

L3Harris has more employees than the Flight recorders (i.e., black boxes) man median and a lower injury rate than the industry's median TCR of 0.7. 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.
