The verdict

NER runs at 80% of its industry's injury rate - safer than the typical Retaining wall, masonry (i.e., block, brick, stone), construction workplace, earning a grade B.

NER: 2.2 TCR = 80% of Retaining wall, masonry (i.e., block, brick, stone), construction BLS 2.8 · 3y Form 300A (see methodology below)

NER safety composite

NER scores strongest on total case rate (tcr) (safer than 73% of same-industry peers) and weakest on dart rate (safer than 44%), 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).
