NEMSI-New London safety composite

NEMSI-New London scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on fatalities (safer than 51%), 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).

Narrower to Connecticut alone (the establishments it most directly competes with for workers and contracts): ranked #6 safest of 54 Plumbing, Heating and Air-Cond employers in Connecticut.

NEMSI-New London (34 employees, TCR 1.5) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

NEMSI-New London has fewer employees than the Plumbing, Heating and Air-Conditioning median and a lower injury rate than the industry's median TCR of 3.3.
