The verdict

Northern runs at 155% of its industry's injury rate - more dangerous than the typical industry workplace, earning a grade D.

Northern: 5.9 TCR = 155% of industry BLS 3.8 · 2y Form 300A (see methodology below)

Northern safety composite

Northern scores strongest on dart rate (safer than 70% 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).
