Alliance Mechanical Concord safety composite

Alliance Mechanical Concord scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 2%), 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 New Hampshire alone (the establishments it most directly competes with for workers and contracts): ranked #28 safest of 31 Plumbing, heating, and air-Con employers in New Hampshire.

Alliance Mechanical Concord (14 employees, TCR 11.2) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

Alliance Mechanical Concord has fewer employees than the Plumbing, heating, and air-Conditioning median and a higher injury rate than the industry's median TCR of 3.3.
