The verdict

L3 Technologies Inc. runs at 12% of its industry's injury rate - far safer than the typical Navigational instruments manufacturing workplace, earning a grade A.

L3 Technologies Inc.: 0.4 TCR = 12% of Navigational instruments manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

L3 Technologies Inc. safety composite

L3 Technologies Inc. scores strongest on total case rate (tcr) (safer than 70% of same-industry peers) and weakest on dart rate (safer than 19%), 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).
