The verdict

NEMSI-Installation runs at 71% of its industry's injury rate - safer than the typical Plumbing, Heating and Air-Conditioning workplace, earning a grade B.

NEMSI-Installation: 2.0 TCR = 71% of Plumbing, Heating and Air-Conditioning BLS 2.8 · 2y Form 300A (see methodology below)

NEMSI-Installation safety composite

NEMSI-Installation scores strongest on total case rate (tcr) (safer than 69% of same-industry peers) and weakest on dart rate (safer than 33%), 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).
