The verdict

Smith NMNH Atrium runs at 44% of its industry's injury rate - far safer than the typical industry workplace, earning a grade A.

Smith NMNH Atrium: 1.3 TCR = 44% of industry BLS 3.0 · 2y Form 300A (see methodology below)

Smith NMNH Atrium safety composite

Smith NMNH Atrium scores strongest on total case rate (tcr) (safer than 87% of same-industry peers) and weakest on dart rate (safer than 31%), 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).
